National Priority List: rr-NPL-bb
Sites on the United States Environmental Protection Agency (EPA)'s National Priorities List of the most serious uncontrolled or abandoned hazardous waste sites identified for possible long-term remedial action under the Superfund program. The NPL, which EPA is required to update at least once a year, is based primarily on the score a site receives from EPA's Hazard Ranking System. A site must be on the NPL to receive money from the Superfund Trust Fund for remedial action. Sites are represented by boundaries where available in the EPA Superfund Site Boundaries maintained by the Shared Enterprise Geodata and Services (SEGS). Site boundaries represent the footprint of a whole site, the sum of all of the Operable Units and the current understanding of the full extent of contamination; for Federal Facility sites, the total site polygon may be the Facility boundary. Where there is no polygon boundary data available for a given site, the site is represented as a point.

EPA Report on the Status of Open Dumps on Indian Lands: rr-IODI-bb Public Law 103-399, The Indian Lands Open Dump Cleanup Act of 1994, enacted October 22, 1994, identified congressional concerns that solid waste open dump sites located on American Indian or Alaska Native (AI/AN) lands threaten the health and safety of residents of those lands and contiguous areas. The purpose of the Act is to identify the location of open dumps on Indian lands, assess the relative health and environment hazards posed by those sites, and provide financial and technical assistance to Indian tribal governments to close such dumps in compliance with Federal standards and regulations or standards promulgated by Indian Tribal governments or Alaska Native entities.
Government Publication Date: Dec 31, 1998
CERCLIS - No Further Remedial Action Planned: rr-CERCLIS NFRAP-bb An archived site is one at which EPA has determined that assessment has been completed and no further remedial action is planned under the Superfund program at this time. The Archive designation means that, to the best of EPA's knowledge, assessment at a site has been completed and that EPA has determined no further steps will be taken to list this site on the National Priorities List (NPL). This decision does not necessarily mean that there is no hazard associated with a given site; it only means that, based upon available information, the location is not judged to be a potential NPL site.

This Per- and Poly-Fluoroalkyl Substances (PFAS) Spills dataset is made available via the U.S. Environmental Protection Agency's (EPA) PFAS Analytic Tools. The National Response Center (NRC), operated by the U.S. Coast Guard, is the designated federal point of contact for reporting all oil, chemical, and other discharges into the environment, for the United States and its territories. This dataset contains NRC spill information from 1990 to the present that is restricted to records associated with PFAS and PFAS-containing materials. Incidents are filtered to include only records with a "Material Involved" or "Incident Description" related to Aqueous Film Forming Foam (AFFF). The keywords used to filter the data included "AFFF," "Fire Fighting Foam," "Aqueous Film Forming Foam," "Fire Suppressant Foam, "PFAS," "PERFL," "PFOA," "PFOS," and "Genx." Limitations: The data from the NRC website contains initial incident data that has not been validated or investigated by a federal/state response agency. Keyword searches may misidentify some incident reports that do not contain PFAS. This dataset should also not be considered to be exhaustive of all PFAS spills/release incidents.

PFAS Waste Transfers from RCRA e-Manifest : rr-PFAS E-MANIFEST-bb This Per- and Poly-Fluoroalkyl Substances (PFAS) Waste Transfers dataset is made available via the U.S. Environmental Protection Agency's (EPA) PFAS Analytic Tools. Every shipment of hazardous waste in the U.S. must be accompanied by a shipment manifest, which is a critical component of the cradle-to-grave tracking of wastes mandated by the Resource Conservation and Recovery Act (RCRA). According to the EPA, currently no Federal Waste Code exists for any PFAS compounds. To work around the lack of PFAS waste codes in the RCRA database, EPA developed the PFAS Transfers dataset by mining e-Manifest records containing at least one of these common PFAS keywords: • PFAS • PFOA • PFOS • PERFL • AFFF • GENX • GEN-X (plus the Vermont state-specific waste codes). Limitations: Amount or concentration of PFAS being transferred cannot be determined from the manifest information. Keyword searches may misidentify some manifest records that do not contain PFAS. This dataset should also not be considered to be exhaustive of all PFAS waste transfers.

This Per- and Poly-Fluoroalkyl Substances (PFAS) Industry Sectors dataset is made available via the U.S. Environmental Protection Agency's (EPA) PFAS Analytic Tools. The EPA developed the dataset from various sources that show which industries may be handling PFAS including: EPA's Enforcement and Compliance History Online (ECHO) records restricted to potential PFAS-handling industry sectors; ECHO records for Fire Training Sites identified where fire-fighting foam may have been used in training exercises; and 14 CFR Part 139 Airports compiled from historic and current records from the FAA Airport Data and Information Portal. Since July 2006, all certificated Part 139 Airports are required to have fire-fighting foam onsite that meet certain military specifications, which to date have been fluorinated (Aqueous Film Forming Foam). Limitations: Inclusion in this dataset does not indicate that PFAS are being manufactured, processed, used, or released by the facility. Listed facilities potentially handle PFAS based on their industrial profile, but are unconfirmed by the EPA. Keyword searches in ECHO for Fire Training sites may misidentify some facilities and should not be considered to be an exhaustive list of fire training facilities in the U.S.

This information was taken from report DRXTH-AS-IA-83A016 (Historical Overview of the Nike Missile System, 12/1984) which was performed by Environmental Science and Engineering, Inc. for the U.S. Army Toxic and Hazardous Materials Agency Assessment Division. The Nike system was deployed between 1954 and the mid-1970's. Among the substances used or stored on Nike sites were liquid missile fuel (JP-4); starter fluids (UDKH, aniline, and furfuryl alcohol); oxidizer (IRFNA); hydrocarbons (motor oil, hydraulic fluid, diesel fuel, gasoline, heating oil); solvents (carbon tetrachloride, trichloroethylene, trichloroethane, stoddard solvent); and battery electrolyte. The quantities of material a disposed of and procedures for disposal are not documented in published reports. Virtually all information concerning the potential for contamination at Nike sites is confined to personnel who were assigned to Nike sites. During deactivation most hardware was shipped to depot-level supply points. There were reportedly instances where excess materials were disposed of on or near the site itself at closure. There was reportedly no routine site decontamination.

RE: DATA GAP INVESTIGATION AND REQUEST FOR SITE CLOSURE 6756 AND 6792 CENTRAL AVENUE
NEWARK, CALIFORNIA
FARALLON PN: 1071-105
Dear Ava Lazor:
Farallon Consulting, L.L.C. (Farallon) has prepared this letter report on behalf of 6756-6792 Central Ave Newark CA LLC (aka Prologis) to present findings from the data gap investigation performed by Farallon and to request case closure for the property at 6756 and 6792 Central Avenue in Newark, California (herein referred to as the Site) (Figure 1). Industrial constituents were identified in soil and groundwater beneath the Site during environmental due diligence activities, as summarized in the Phase I Environmental Site Assessment Report dated June 12, 2019 (2019 Phase I Report).1 6756-6792 Central Ave Newark CA LLC became the Site owner in July 2019 and intends to further evaluate Site conditions to determine what actions, if any, are required to remedy the identified industrial impact. The Site was originally entered into the Leaking Underground Storage Tank program under Alameda County Water District (ACWD) oversight, but at the request of ACWD was transferred to the Site Cleanup Program.
This letter report provides a brief background of the Site; a current conceptual site model (CSM); a summary of the scope of work and the results from the temporary groundwater monitoring well installation and groundwater monitoring event conducted on March 2, 2023 in accordance with the ACWD-approved Data Gap Investigation Work Plan2 prepared by Farallon and the Sampling and Analysis Plan presented as Table 1; Farallon’s conclusions 1 Farallon. 2019.

including a comparison of Site conditions with the Assessment Tool for Closure3 criteria; and Farallon’s recommendations, which include a recommendation for No Further Action status and regulatory case closure for the Site.
SITE BACKGROUND
The Site consists of Alameda County Assessor’s Parcel Nos. 92A-2165-14 (2.03 acres), 92A-2165-15 (8.18 acres), 92A-2165-16 (2.79 acres), and 92A-2165-17 (4.23 acres), which total approximately 17.23 acres of land. At the time of the 2019 Phase I Report, the Site was developed with five buildings (a large building consisting of conjoined structures, a large industrial building along Central Avenue, a medium-sized building, and two smaller buildings) constructed in phases between 1946 and 1968 and occupied by industrial tenants. Between 2019 and 2022, all Site buildings except the large industrial building along Central Avenue were demolished in preparation for Site redevelopment with an industrial logistics building. Access to the Site is gained from Central Avenue, west of the Site. Former Site operations included use of two 1,000-gallon underground storage tanks containing bunker fuel and gasoline, and a 20,000-gallon diesel fuel aboveground storage tank and associated fuel islands and piping, all of which were removed from the Site between 1991 and 1993. Evidence of a release was not detected during the removal of the underground storage tanks. A release from the aboveground storage tank was detected and remediated via removal of approximately 311 tons of impacted soil and 2,300 gallons of impacted groundwater. Confirmation samples collected following excavation and dewatering did not contain detectable concentrations of petroleum constituents.
As summarized in the 2019 Phase I Report, Farallon performed an environmental investigation at the Site in phases in April and May 2019, which consisted of collecting soil and reconnaissance groundwater samples for laboratory analysis. The results from the investigation suggested that a release of total petroleum hydrocarbons (TPH) as diesel-range organics (DRO) and as oil-range organics (ORO) from historical operations occurred at the Site. Volatile constituents were not detected in groundwater samples at concentrations exceeding San Francisco Bay Regional Water Quality Control Board (Water Board) vapor intrusion human health risk Environmental Screening Levels (ESLs) for commercial/industrial properties.

After the completion of the 2019 Phase I Report, eight groundwater monitoring wells (MW-1 through MW-8) were installed at the Site, as documented in the letter regarding Groundwater Monitoring Well Installation and Sampling dated April 20, 2020.4 DRO was detected at a concentration of 3,400 milligrams per kilogram (mg/kg) in the soil sample collected from boring MW-8 at a depth of 3 feet below ground surface (bgs), which exceeds the commercial/industrial ESL of 1,200 mg/kg. ORO and naphthalene were detected at concentrations of 9,700 and 2.7 mg/kg, respectively, in the soil sample collected from boring MW-8 at a depth of 3 feet bgs, which is less than the commercial/industrial ESLs of 180,000 and 17 mg/kg, respectively. The lithology beneath the Site consists of sand and gravel from the surface to depths of approximately 2 to 4 feet bgs, followed by clay and silt to depths of approximately 7.5 to 11 feet bgs, and by silt and sand to depths of approximately 13 to 14 feet bgs, where first-encountered groundwater was observed. This shallow water-bearing zone consists of silty sand and sand, and extends to depths of 19 to 22 feet bgs. Beneath the shallow water-bearing zone, an aquitard of silt and clay corresponding to the Newark Aquiclude was identified, extending to the total depth explored of 25 feet bgs. Monitoring well locations are shown on Figure 2.
Groundwater monitoring data were obtained during four groundwater monitoring events, with the findings summarized in the letter regarding First and Second Quarter 2021 Groundwater Monitoring and Request for Site Closure dated March 24, 2022.5 Groundwater data collected using low-flow sampling procedures at the Site in 2020 and 2021 indicated that Site groundwater has not been adversely impacted by DRO or polycyclic aromatic hydrocarbons (PAHs) at concentrations exceeding the maximum contaminant level (MCL), with the exception of the results from groundwater samples collected from monitoring wells MW-5 and MW-8 on January 13 and April 6, 2021, which indicated that groundwater impacts appeared to be low threat and limited in areal extent. Data suggest that the DRO impact in groundwater may be from natural organic compounds (NOCs) or hydrocarbon oxidation products (HOPs) at concentrations less than the MCL for HOPs. Data suggest the potential for releases from surrounding properties to have contributed to groundwater impacts at the Site. According to data obtained during five groundwater monitoring events conducted in 2020, 2021, and 2023, the groundwater flow direction at the Site is southwest, with a gradient of 0.001 to 0.004 foot per foot.

and flow direction are shown on Figure 3. Historical laboratory analytical results, monitoring well construction details, and groundwater elevation measurements are presented in Tables 2 through 13. Based on the findings of the previous investigations and groundwater monitoring, Farallon requested case closure under the Water Board Low-Threat Closure Policy.
In the letter regarding Denial of Low-Threat Underground Storage Tank Case Closure Request dated May 20, 2022,6 ACWD identified four criteria where additional data are required to qualify for case closure:
1) Update the CSM to include a description of the Newark Aquifer, the shallowest regional aquifer in the Site vicinity and a source of drinking water, and describe the potential impacts to the Newark Aquifer from releases at the Site; 2) Conduct additional sampling to delineate the down-gradient extent of the contaminant plume exceeding water quality objectives, and evaluate whether petroleum hydrocarbons detected in groundwater are hydrocarbon oxidation products;
3) Update the vapor intrusion to indoor air risk assessment; and 4) Update the CSM to address the potential discharge of impacted groundwater from the Site to the nearby aquatic habitats of the San Francisco Bay and/or salt ponds.
To fulfill ACWD’s four criteria, Farallon prepared the Data Gap Investigation Work Plan, which was revised via email to Ava Lazor of ACWD on October 28, 2022.7 In addition, because the evidence of a release at the Site originated primarily from the former 10,000-gallon aboveground storage tank, the case was transferred to the Site Cleanup Program, and ACWD stated that suitability for closure of the Site should be evaluated using the Assessment Tool for Closure. Although the criteria outlined in the Assessment Tool for Closure are intended for chlorinated solvent impacted properties, they are applicable to other contaminated properties such as the Site.

Newark, California identified as Alameda County Assessor’s Parcel Nos. 537-0751-007-01, 537-0751-008, and 0920253-002-01. Prologis entered into an access agreement with Cargill to advance borings F-26, F-27, and F-28 at the Cargill property. Cargill provided to Prologis a Soil Removal and Closure Report8 that documented the removal of soil and groundwater impacted by a release of bunker fuel from three aboveground storage tanks formerly located at the Cargill property. The three former bunker fuel aboveground storage tanks were removed from the Cargill property by approximately 1959. A 1959 aerial photograph reportedly showed an area of dark stained soil around the positions of the former bunker fuel aboveground storage tanks. In the 1960s, a single-story building identified as the Cargill admin building (Figure 2) was built on top of the location of one of the former bunker fuel aboveground storage tanks. Approximately 2,900 tons of soil and 2,000 gallons of water were removed from two remedial excavations proximate to the north and east of the Cargill admin building. Excavation of impacted soil was limited by the presence of the Cargill admin building. Residual bunker fuel impacts left in-place beneath the Cargill admin building were demonstrated by concentrations of TPH in soil samples collected from locations adjoining the Cargill admin building. TPH were detected in sidewall soil samples CSEX1-#1, CSEX1-#7, CSEX2-#1, and CSEX2-#2 at concentrations of 2,200, 3,000, 6,400, and 6,400 mg/kg, respectively, at a depth of approximately 7.5 feet bgs.
There is not an ESL established for bunker fuel. Samples CSEX1-#1 and CSEX1-#7 were located north of the Cargill admin building, and samples CSEX2-#1 and CSEX2-#2 were located east of the Cargill admin building.

A CSM is presented in Table 14. The CSM presents a set of working hypotheses regarding all aspects of the contaminant release at the Site, including regional and Site geology and hydrogeology; a review of sensitive receptors; constituents of concern (COCs); the release source; a review of contamination identified in soil and groundwater; source removal activities; and a risk evaluation. The CSM presented in Table 14 has been updated to discuss the Newark Aquifer and the nearby aquatic habitats of the salt ponds and San Francisco Bay.

The following sections provide a summary of the scope of work and results for the implementation of the temporary groundwater monitoring well installation and groundwater monitoring event presented in the Data Gap Investigation Work Plan.
Permitting
Prior to commencing drilling activities, Farallon obtained ACWD Drilling Permit No. 2023-023 from ACWD. The approved permit is provided in Attachment A.
Health and Safety Plan
Per Section 3203 of Title 8 of the California Code of Regulations (8 CCR 3203), a Health and Safety Plan (HASP) is required for all field activities, due to the potential for exposure to hazardous substances. Farallon prepared a HASP prior to commencement of any field activities. The HASP complied with the requirements of the Occupational Safety and Health Act of 1970 and 8 CCR 3203.
March 2, 2023 Temporary Groundwater Monitoring Well Installation and Destruction On March 2, 2023, three temporary groundwater monitoring wells (F-26 , F-27, and F-28) were installed for the collection of groundwater samples at the property south-adjacent and down-gradient of the Site. Boring locations for installation of temporary groundwater monitoring wells are shown on Figure 2.
The borings for installation of temporary monitoring wells were advanced by Cascade Drilling, L.P., a California-licensed C-57 contractor, using a hand auger to depths ranging from 6 to 8 feet bgs. A Farallon Scientist observed subsurface conditions during drilling and recorded Unified Soil Classification System descriptions, soil moisture, occurrence of groundwater, physical indications of potential contamination (e.g., odor, staining), and fieldscreening results obtained using a photoionization detector on Farallon’s Log of Boring, presented in Attachment B. Soil cuttings generated during the drilling for installation of temporary monitoring wells were containerized pending characterization for off-Site disposal.

Temporary groundwater monitoring wells F-26, F-27, and F-28 were constructed using prepacked 3/4-inch polyvinyl chloride with 5 feet of 0.010-inch slotted screen and 20/40 sand contained within a steel mesh. Farallon collected groundwater level measurements and groundwater samples as described below. After sampling, the temporary groundwater monitoring wells F-26 through F-28 were destroyed by removing the pre-packed well casing and sand, and backfilling the boring with neat cement in accordance with ACWD permit requirements.
March 2, 2023 Groundwater Monitoring
Groundwater samples were collected from temporary groundwater monitoring wells F-26 through F-28 and existing monitoring wells MW-3 through MW-8. Groundwater samples were collected from temporary groundwater monitoring wells F-26 through F-28 to evaluate potential impacts to shallow groundwater down-gradient of the Site. Groundwater samples were collected from existing monitoring wells MW-3, MW-4, MW-6, and MW-7 to evaluate background concentrations; MW-5 to evaluate DRO and PAHs, which were detected in historical groundwater samples at concentrations greater than their respective commercial/industrial ESLs; and MW-8 to evaluate PAHs, which were detected in historical groundwater samples at concentrations greater than commercial/industrial ESLs.
Groundwater-level measurements and groundwater samples were collected using low-flow groundwater sampling procedures on March 2, 2023. Groundwater sampling was conducted in accordance with Farallon’s standard operating procedures, provided in Attachment C.
Groundwater samples were submitted to McCampbell Analytical Inc. of Pittsburg, California, accredited under the California State Environmental Laboratory Accreditation Program for analysis in accordance with the Data Gap Investigation Work Plan and the Sampling and Analysis Plan provided in Table 1.
March 2, 2023 Groundwater Monitoring Results
Groundwater monitoring well construction information is summarized in Table 7; current and historical groundwater elevations are summarized in Table 8. Current and historical groundwater analytical results for TPH including HOPs, VOCs, PAHs, metals, and total dissolved solids (TDS) are summarized in Tables 9 through 13, respectively. The analytical results were compared with Tier 1 ESLs, MCLs, and other commercial/industrial values.
Field forms used for the groundwater monitoring events are provided in Attachment D. The laboratory analytical reports are provided in Attachment E. The measured groundwater elevations and calculated groundwater flow direction for the March 2, 2023 groundwater monitoring event are shown on Figure 3.

The depth to water varied between 2.70 and 5.25 feet below the ground surface or top of the monitoring well casing (Table 1). The water-level elevation was calculated to be between
14.40 and 17.12 feet above mean sea level (Table 8). The groundwater flow direction was calculated to be southwest at a gradient of approximately 0.004 foot per foot, as illustrated on Figure 3.
DRO analyzed without and with silica gel cleanup was detected at concentrations of 200 and 130 micrograms per liter (µg/l), respectively, in reconnaissance groundwater sample F-26, which exceed the Tier 1 ESL of 100 µg/l but are equal to or less than the MCL of 200 µg/l. In the laboratory report, the fuel pattern for reconnaissance groundwater sample F-26 was qualified as “diesel range compounds are detected; no recognizable pattern.” However, the analytical laboratory stated via email (May 12, 2023 email)9 that reconnaissance groundwater sample F-26 showed a “…possible degraded bunker [fuel] oil pattern. It’s missing the characteristic alkane peaks but does show pattern across [the] entire [bunker fuel oil] BO range” in the DRO analyses without and with silica gel cleanup. The potential exists for residual bunker fuel impacts left in-place beneath the Cargill admin building to have contributed to impact identified in the sample from F-26. DRO analyzed without silica gel cleanup was detected at a concentration of 120 µg/l in reconnaissance sample F-27, which is greater than the Tier 1 ESL of 100 µg/l but less than the MCL of 200 µg/l. The analytical laboratory stated via the May 12, 2023 email that DRO detected without silica gel cleanup in reconnaissance groundwater sample F-27 did not match diesel or bunker fuel patterns. DRO analyzed with silica gel cleanup was not detected at a concentration exceeding laboratory reporting limit in reconnaissance groundwater sample F-27. Detections of DRO in sample F-27 likely represent HOPs, as discussed below. DRO analyzed without or with silica gel cleanup was not detected at a concentration exceeding laboratory reporting limits in reconnaissance groundwater sample F-28. DRO analyzed with or without silica gel cleanup was not detected at a concentration exceeding laboratory reporting limits in the groundwater samples collected from monitoring wells MW-3 through MW-8. Concentrations of DRO analyzed with or without silica gel cleanup were less than the saltwater ECOTOX ESLs in reconnaissance groundwater samples F-26, F-27, and F-28, and groundwater samples collected from monitoring wells MW-3 through MW-8.

The following formula provided in the ESL User’s Guide10 was used to calculate HOPs present in reconnaissance samples F-26, F-27, and F-28 and samples collected from monitoring wells MW-3 through MW-8 during the March 2, 2023 groundwater monitoring event.
[HOPS] = [Total Organics] – [PHCs] – [NOCs]
Where:
[] = Concentration
[Total Organics] = Plume sample analyzed for DRO C10-C28 without silica gel cleanup [PHCs] = Petroleum hydrocarbons; the same plume sample analyzed for DRO C10-C28 with silica gel cleanup
[NOCs] = Natural organic compounds; a sample from an unimpacted (background) area with similar vegetative and hydrogeologic characteristics as plume sample analyzed for DRO C10-C28 without silica gel cleanup
For the calculation of HOPs, the NOCs value was determined to be zero based on non-detect values for DRO C10-C28 without silica gel cleanup in groundwater samples collected from up-gradient monitoring wells MW-3 and MW-4. In addition, the HOPs calculations conservatively used zero for the PHCs value when concentrations of DRO C10-C28 with silica gel cleanup were less than the laboratory detection limit of 100 µg/l. Concentrations of HOPs were calculated to be 170 and 140 µg/l in reconnaissance groundwater samples F-26 and F-27, respectively, which exceed the Tier 1 ESL of 100 µg/l but are less than the MCL of 410 µg/l. HOPs were not detected in the reconnaissance groundwater sample F-28 or the samples collected from groundwater monitoring wells MW-3 through MW-8.
Calculated HOPs concentrations were less than the saltwater ECOTOX ESL of 510 µg/l in reconnaissance samples F-26, F-27, and F-28 and samples collected from monitoring wells MW-3 through MW-8. The calculation of HOPs for sample MW-5 resulted in a negative value.
The analytical laboratory stated via email11 that both the MW-5 analysis without and with silica gel cleanup were performed on the same gas chromatograph and calibration run. No carryover for samples treated with silica gel was found as the samples were analyzed after the method blank. The analytical laboratory had disposed of sample MW-5 by the time this was discovered and was not able to re-extract the sample for further investigation of the issue. The issue was found to not be significant due to the relatively low concentration of 10 Water Board. 2019. User’s Guide: Derivation and Application of ESLs (ESL User’s Guide). 11 McCampbell. 2023.

DRO C10-C28 with silica gel cleanup detected in the sample collected from monitoring well MW-5.
ORO analyzed without and with silica gel cleanup was detected at concentrations of 860 and 430 µg/l, respectively, in reconnaissance groundwater sample F-26. ORO analyzed without or with silica gel cleanup was not detected at a concentration exceeding laboratory reporting limits in the reconnaissance groundwater samples F-27 and F-28 or in groundwater samples collected from monitoring wells MW-3 through MW-8. ESLs have not been established for ORO.
Several PAHs were detected at concentrations exceeding laboratory detection limits in the groundwater samples. PAHs were not detected at concentrations exceeding Tier 1 ESLs in reconnaissance groundwater samples collected from temporary monitoring wells F-26, F-27, and F-28 or groundwater samples collected from monitoring wells MW-3, MW-4, MW-6, and MW-7. Benzo(a)pyrene, benzo(b)fluoranthene, chrysene, and indeno(1,2,3-cd)pyrene were detected at concentrations exceeding Tier 1 ESLs but less than the MCLs in groundwater samples from monitoring well MW-5. Benzo(a)pyrene was detected at a concentration exceeding the Tier 1 ESL but less than the MCL in groundwater samples from monitoring well MW-8. Concentrations of benzo(a)anthracene and naphthalene, the only PAHs with established vapor intrusion human health risk level ESLs for commercial/industrial properties, were either not detected or detected at concentrations significantly less than the vapor intrusion ESLs in groundwater samples collected during the March 2023 sampling event. Concentrations of PAHs were less than the saltwater ECOTOX ESL of 510 µg/l in reconnaissance samples F-26, F-27, and F-28 and samples collected from monitoring wells MW-3 through MW-8.
TDS were detected at a maximum concentration of 11,300 mg/l in the reconnaissance groundwater sample F-27. However, the laboratory noted that the reconnaissance groundwater samples F-26, F-27, and F-28 were aqueous solutions containing greater than approximately 1 percent sediment by volume, which likely contributed to the high TDS concentrations. TDS in groundwater monitoring wells at the Site were detected at a maximum concentration of 1,960 mg/l in the groundwater sample collected from monitoring well MW-8. The Secondary MCL range for TDS is 500 mg/l (recommended) to 1,000 mg/l (upper).12 Detected TDS concentrations in groundwater monitoring wells installed in shallow 12 California State Water Resources Control Board. 2018.

water-bearing zones at the Site are indicative of brackish water. Shallow groundwater at the Site is contained in shallow water-bearing zones of the Newark Aquiclude, which are not expected to have beneficial use, and the presence of the Newark Aquiclude prevents significant downward migration of impacted groundwater from shallow water-bearing zones to the Newark Aquifer.
Waste Disposal
Disposable sampling and health and safety supplies and equipment were disposed of in an appropriate waste dumpster. Soil cuttings, excess groundwater, and decontamination water were stored in 55-gallon drums pending receipt of laboratory analytical results. Drums were stored on the Site in coordination with the Site owner. Laboratory analytical results from a sample collected from the drum of soil cuttings and groundwater monitoring results from this data gap investigation were used to profile the waste and identify appropriate disposal options. Contents of the drums were classified as nonhazardous and the drums were removed from the Site by Belshire Environmental Services, Inc. for disposal on May 8, 2023.
Waste manifests are provided in Appendix F.
3) UPDATE THE VAPOR INTRUSION TO INDOOR AIR RISK ASSESSMENT The vapor intrusion to indoor air risk assessment has been updated to include the most recent data collected during implementation of the Data Gap Investigation Work Plan. The cumulative vapor intrusion exposure risk and hazard were calculated by entering maximum concentrations of volatile COCs detected in groundwater samples collected from monitoring wells into the Water Board ESL Tier 2 – Site-Specific Cumulative Risk and Hazard Calculator,13 presented in Attachment G. Only COCs that contribute to vapor intrusion exposure risk and hazard were included in the risk assessment calculations. For example, DRO was detected in groundwater, but because it does not have a commercial/industrial vapor intrusion human health risk level ESL, it does not contribute to the calculation for cumulative vapor intrusion exposure risk and hazard, and was not included in the calculation of vapor intrusion exposure risk and hazard. A review of historical data collected at the Site found detections of four COCs that contribute to the calculation for cumulative vapor intrusion exposure risk and hazard: methyl ethyl ketone, methyl tertiary-butyl ether, benzo(a)anthracene, and naphthalene. The maximum detected concentration in groundwater monitoring well samples for each of the four COCs was entered into the calculation presented in Appendix F. Cumulative cancer risk and noncancer hazard due to 13 Water Board. 2019. Environmental Screening Levels, Table T2-2: Tier 2 – Site-Specific Cumulative Risk and Hazard Calculator. Rev. 2.

vapor intrusion were 6.3E-09 and 1.5E-04, respectively, which are less than the cancer risk and the noncancer hazard thresholds of 1.0E-6 and 1.0, respectively. Although no soil gas samples have been collected at the Site, the plethora of soil and groundwater samples with concentrations of all COCs less than commercial/industrial vapor intrusion human health risk level ESLs, and the cumulative cancer risk and noncancer hazard less than thresholds illustrate that subsurface conditions do not expose commercial workers to unacceptable health risks under continued commercial use.
CONCLUSIONS
The groundwater flow direction at the Site was calculated to be southwest at a gradient of approximately 0.004 foot per foot during the March 2, 2023 groundwater monitoring event, which is consistent with previous results.
Analytical results indicate that concentrations of COCs in groundwater at the Site are less than MCLs. The concentrations of DRO and PAHs detected in groundwater at the Site have decreased from slightly greater than the MCLs to less than the MCLs in the most recent groundwater monitoring event. COCs were not detected at concentrations exceeding the MCLs in the reconnaissance groundwater samples F-26, F-27, and F-28, and the contaminant plume exceeding water quality goals has been delineated in the down-gradient direction. The concentrations of volatile COCs detected in groundwater samples collected from on-Site monitoring wells MW-3 through MW-8 on March 2, 2023 were less than the commercial/industrial ESL for vapor intrusion human health risk level. The concentrations of COCs detected in reconnaissance samples F-26, F-27, and F-28 and samples collected from monitoring wells MW-3 through MW-8 were less than saltwater ECOTOX ESLs.
The Site is in the Niles Cone Groundwater Basin, where groundwater is considered to have beneficial use, per the Basin Plan.14 However, groundwater quality within the Newark Aquifer near the San Francisco Bay has been degraded by saltwater intrusion. Detected TDS concentrations in groundwater monitoring wells installed in shallow water-bearing zones at the Site are indicative of brackish water, which is expected given the proximity of the Site to the San Francisco Bay and salt ponds. Shallow groundwater at the Site is contained in shallow water-bearing zones of the Newark Aquiclude, which are not expected to have beneficial use, and the presence of the Newark Aquiclude prevents significant downward 14 Water Board. 2019.

migration of impacted groundwater from shallow water-bearing zones to the Newark Aquifer.
The down-gradient salt ponds and the San Francisco Bay were identified approximately 100 feet southwest and 2.5 miles southwest of the Site, respectively, and it is highly unlikely that they have been impacted by historical releases at the Site because COCs were not detected at concentrations exceeding aquatic habitat ESLs in the down-gradient groundwater samples F-26, F-27, and F-28. The nearest down-gradient water-supply well is approximately 1,600 feet southwest of the Site. Based on the distance to the water-supply well from the Site and the low concentrations of COCs detected in groundwater at the Site, it is highly unlikely that historical releases at the Site have impacted water-supply wells or have the potential to impact water-supply wells in the future.
Based on the findings of this data gap investigation, the CSM is complete, with no remaining data gaps. Pollutant sources have been remediated to the extent feasible. Residual chemical impact beneath the Site does not pose an unacceptable risk to human health, ecological health, or sensitive receptors, considering current and identifiable future land and water uses. Residual chemical impact does not pose an unacceptable threat to groundwater and surface water resources, considering current and identifiable future beneficial uses.
Detections of COCs in the groundwater plume have decreased from slightly exceeding the MCLs to less than the MCLs in the most recent groundwater monitoring event performed on March 2, 2023, and cleanup standards have been met. Based on a review of Site conditions compared with the Assessment Tool for Closure, as summarized in Table 15, it is Farallon’s opinion that the closure criteria have been met.
RECOMMENDATIONS
It is Farallon’s opinion that the Site qualifies for closure under the Assessment Tool for Closure. Farallon recommends that the Site be granted No Further Action status and regulatory case closure. Upon receipt of concurrence from ACWD, Farallon will arrange for destruction of the Site monitoring wells.

Description
Geology and
Hydrogeology Regional
The Site is in Newark, California along the southeastern coast of the San Francisco Bay, the main water body in Newark. The Site is characterized by Quaternary alluvium and marine deposits, which are composed of sequences of interbedded silts, sands, and clays to depths greater than 200 feet below ground surface (bgs). Alluvial deposits range in age from Pliocene to Holocene. The Site is in the Niles Cone Groundwater Basin, and groundwater flow beneath the region is predominantly to the west-southwest.
As described in the Urban Water Management Plan,1 the shallowest aquifer of the Niles Cone Groundwater Basin is the Newark Aquifer, which consists of gravel and sand between depths of approximately 40 and 140 feet bgs. The Newark Aquifer is overlain in most of the basin by the Newark Aquiclude, consisting of silt and clay. Layers of sand and silt within the Newark Aquiclude can act as non-regional shallow water-bearing zones. Beneath the Newark Aquifer is a clay aquitard that separates the Newark Aquifer from the Centerville Aquifer, Fremont Aquifer, and the Deep Aquifer. The Newark Aquifer is generally confined except in the area immediately west of the Hayward fault, where the overlying aquitard is absent in the forebay area.
Groundwater in the Niles Cone Groundwater Basin has beneficial use per the Basin Plan.2 The Newark Aquifer is a source of drinking water among other beneficial uses. However, groundwater quality within the Newark Aquifer near the San Francisco Bay has been degraded by saltwater intrusion. Aquifer reclamation wells up-gradient of the Site prevent further saltwater intrusion to protect drinking water as a beneficial use. As a result of the Site’s location relative to the San Francisco Bay and up-gradient aquifer reclamation wells, groundwater within the Newark Aquifer beneath the Site is expected to be brackish and is not expected to be used for drinking water. Shallow water-bearing zones within the Newark Aquiclude are also expected to be brackish and are not expected to have beneficial use. The presence of the Newark Aquiclude prevents significant downward migration of impacted groundwater from shallow water-bearing zones within the Newark Aquiclude to the Newark Aquifer.
Geology and
Hydrogeology Site
According to investigations conducted by Farallon Consulting, L.L.C. (Farallon), the lithology beneath the Site consists of sand and gravel from the surface to depths of approximately 2 to 4 feet bgs, followed by clay and silt to depths of approximately 7.5 to 11 feet bgs, and by silt and sand to depths of approximately 13 to 14 feet bgs, where firstencountered groundwater was observed. This shallow water-bearing zone consists of silty sand and sand, and extends to depths of 19 to 22 feet bgs. Beneath the shallow water-bearing zone, an aquitard of silt and clay corresponding to the Newark Aquiclude was identified, extending to the total depth explored of 25 feet bgs. According to data obtained during five groundwater monitoring events conducted in 2020, 2021, and 2023, the groundwater flow direction at the Site is southwest, with a gradient of 0.001 to 0.004 foot per foot. 1 Alameda County Water District. 2021.

Water
Bodies
The federally designated wetlands nearest the Site are salt ponds that were identified approximately 100 feet southwest of the Site on the southwest-adjacent Cargill Salt property at 7220 Central Avenue. The water body nearest the Site was identified as the San Francisco Bay, approximately 2.5 miles southwest of the Site.
Sensitive
Receptors Nearby Wells
Water-supply wells within a 1-mile radius of the Site were identified in the California State Water Resources Control Board Groundwater Ambient Monitoring and Assessment Program database. Two wells were identified approximately 3,168 and 4,800 feet northeast and up-gradient of the Site. Five wells were identified approximately 1,600 to 4,200 feet southwest and down-gradient of the Site. Based on the distance of these wells from the Site and/or the direction of groundwater flow, it is highly unlikely that historical releases at the Site have impacted these water-supply wells or have the potential to impact water-supply wells in the future.
Constituents
of Concern
Historical industrial use of the Site indicated the need for investigations at the Site. Previous investigations included laboratory analysis for: total petroleum hydrocarbons (TPH) as diesel-range organics (DRO), as oil-range organics (ORO), and as gasoline-range organics (GRO); polycyclic aromatic hydrocarbons (PAHs); polychlorinated biphenyls; metals; and volatile organic compounds (VOCs). The constituents of concern (COCs) for the Site are compounds that have been detected at concentrations exceeding Tier 1 Environmental Screening Levels (ESLs), which were identified during investigations as DRO, ORO, VOCs, PAHs, and select metals. Groundwater monitoring well sampling results confirmed that historical reconnaissance groundwater sample analytical results are not representative of groundwater conditions at the Site.
Release
Source
Two 1,000-gallon underground storage tanks (USTs) containing bunker fuel and gasoline, and a 20,000-gallon diesel fuel aboveground storage tank (AST) and associated fuel islands and piping were removed from the Site between 1991 and 1993. Visual inspection and soil sampling at the time of removal indicated that a release had not occurred from the two USTs. Although visual inspection of the AST, associated fuel islands, and piping did not indicate that a release had occurred, DRO was detected at a maximum concentration of 2,800 milligrams per kilogram (mg/kg) in soil samples collected. A soil and groundwater investigation was conducted in September 1999 to determine the extent of petroleum hydrocarbon contamination from the AST. Based on the results from the investigation, an excavation was conducted north of the former location of the AST in June 2000, and approximately 311 tons of soil and 2,300 gallons of groundwater were removed from the Site. Confirmation samples collected following excavation did not contain detectable concentrations of TPH. Historical industrial operations at the Site may have been a potential source of impacts to soil and groundwater. Data obtained during five groundwater monitoring events using low-flow sampling procedures at the Site in 2020, 2021, and 2023 indicated that Site groundwater has not been adversely impacted by DRO or PAHs at concentrations exceeding the maximum contaminant level (MCL), with the exception of the results from groundwater samples collected from monitoring wells MW-5 and MW-8 on January 13 and April 6, 2021, which indicated that groundwater impacts appeared to be low threat and limited in areal extent. The March 2, 2023 groundwater monitoring event found that detections of DRO and PAHs in samples collected from off-Site down-gradient Table 14

Description
temporary groundwater monitoring wells F-26, F-27, and F-28 and Site monitoring wells MW-3 through MW-8 were less than MCLs. Groundwater impacts at the Site have been characterized and are low threat. Data suggest the potential for releases from surrounding properties to have contributed to groundwater impacts at the Site.

in Soil
COC detections in soil samples collected by Farallon are summarized below:
• DRO was not detected at a concentration exceeding Tier 1 ESLs, with the exception of a detection of DRO in the sample collected from boring MW-8, which also exceeded the commercial/industrial ESL. • ORO was not detected at a concentration exceeding Tier 1 ESLs, with the exception of a detection of ORO in the sample collected from boring MW-8, which was less than the commercial/industrial ESL. • VOCs were not detected at a concentration exceeding Tier 1 ESLs, with the exception of naphthalene, which was detected at concentrations less than the commercial/industrial ESL in samples collected from borings F-4, F-20, and MW-8.
• PAHs were not detected at a concentration exceeding Tier 1 ESLs, with the exception of two compounds detected at concentrations less than the commercial/industrial ESL in a sample collected from boring F-13. • Arsenic, barium, nickel, and vanadium were the only metals detected at concentrations exceeding Tier 1 ESLs; all concentrations were less than commercial/industrial ESLs. Arsenic is known to occur naturally at concentrations exceeding the commercial/industrial ESL in California soil. The San Francisco Bay Regional Water Quality Control Board has identified 11 mg/kg of arsenic as an acceptable background concentration in soil. The arsenic concentrations detected at the Site were less than this background concentration, with the exception of a detection of 12 mg/kg in a sample collected from boring F-12.

Description
Constituents
of Concern in
Groundwater
COC detections in groundwater samples collected by Farallon are summarized below:
• DRO was detected in two samples collected from monitoring well MW-5, with the maximum concentration of 220 micrograms per liter (µg/l) in the sample collected on April 6, 2021 slightly exceeding the MCL of 200 µg/l. DRO was not detected at a concentration exceeding the laboratory reporting limit in the sample collected from monitoring well MW-5 and analyzed for DRO with silica gel cleanup, which is indicative of the presence of natural organic compounds or hydrocarbon oxidation products (HOPs) in groundwater. Subsequent results of groundwater monitoring at monitoring well MW-5 found DRO without or with silica gel cleanup was not detected exceeding the laboratory reporting limit. DRO without and with silica gel cleanup was detected in off-Site reconnaissance groundwater sample F-26 collected on March 2, 2023, at concentrations equal or less than the MCL, respectively. The chromatograph pattern of the DRO detected in sample F-26 matched a degraded bunker fuel pattern, rather than diesel, which is consistent with residual bunker fuel impacts remaining beneath the Cargill admin building south of the Site. The concentration of HOPs calculated for sample F-26 was less than the MCL. DRO without silica gel cleanup was detected in off-Site reconnaissance groundwater sample F-27 at a concentration less than the MCL. The concentration of HOPs calculated for sample F-27 was less than the MCL. • ORO was detected in the sample collected on January 13, 2021 from monitoring well MW-5. ORO was detected in reconnaissance groundwater sample F-26 collected on March 2, 2023. An ESL has not been established for ORO.
• VOCs were not detected at a concentration exceeding Tier 1 ESLs or MCLs. • Historically, select PAHs were detected at concentrations exceeding Tier 1 ESLs and benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene and dibenzo(a,h)anthracene were detected at maximum concentrations of
0.096, 0.28, 0.36, and 0.049 µg/l, respectively, which slightly exceeded the MCLs of 0.017, 0.2, 0.25 and 0.025 µg/l, respectively. During the most recent groundwater monitoring event on March 2, 2023, PAHs were not detected at concentrations exceeding the MCLs.
Source
Removal
Activities
USTs formerly present at the Site consisted of two 1,000-gallon USTs containing bunker fuel and gasoline, and a 20,000-gallon diesel fuel AST. The former USTs, AST, and associated fuel islands and piping were removed from the Site between 1991 and 1993, stopping any releases that may have occurred. An excavation was conducted north of the former location of the AST in June 2000, and approximately 311 tons of soil and 2,300 gallons of groundwater were removed from the Site. Confirmation samples collected following excavation did not contain detectable concentrations of petroleum hydrocarbons.

Evaluation
Potential
Receptors
The Site is used for commercial/industrial purposes, with no changes in Site use planned for the future. Potential receptors are commercial/industrial workers and construction workers. Potential exposure pathways evaluated were incidental ingestion, dermal contact, dust inhalation, and vapor inhalation. An assessment of whether an exposure pathway is potentially complete, incomplete, or insignificant follows.
For direct contact with contaminated soil, the exposure pathways for incidental ingestion, dermal contact, and dust inhalation for commercial/industrial workers are considered complete. However, shallow soil throughout the Site has been sampled and analyzed, demonstrating concentrations of COCs less than commercial/industrial ESLs, which reflect the intended use of the Site. The only exceptions were a detection of arsenic that slightly exceeded the acceptable background concentration, and a detection of DRO that exceeded the commercial/industrial ESL.
For direct contact with contaminated groundwater, the ingestion and dermal pathways for groundwater are considered incomplete. Shallow groundwater from permanent groundwater monitoring wells across the Site was sampled and analyzed during five sampling events conducted from March 2020 to March 2023. Free-product was not encountered during the five sampling events. Concentrations of COCs detected in groundwater samples were less than the direct exposure human health risk level ESLs, with the exceptions of a concentration of DRO detected in a groundwater sample collected from monitoring well MW-5 on April 6, 2021, and concentrations of select PAHs detected in samples collected from monitoring wells MW-5 and MW-8 on March 5, 2020 and January 13 and April 6, 2021. DRO was not detected at a concentration exceeding the laboratory reporting limit in the groundwater sample collected concurrently from monitoring well MW-5 on April 6, 2021 and analyzed by U.S. Environmental Protection Agency Method 8015 with silica gel cleanup, which is indicative of the presence of natural organic compounds or HOPs in groundwater.
Subsequent groundwater monitoring performed on March 2, 2023 found concentrations of DRO without and with silica gel cleanup were not detected exceeding laboratory reporting limits in samples collected from monitoring wells MW-3 through MW-8 at the Site. Calculated HOPs concentrations were not detected in samples collected from monitoring wells MW-3 through MW-8 at the Site. The detected concentrations of DRO and PAHs historically detected in samples collected from monitoring wells MW-5 and MW-8 appear to be decreasing. Down-gradient and off-Site reconnaissance groundwater samples collected from temporary monitoring wells F-26, F-27, and F-28 have delineated the downgradient extent of the contaminant plume.
The Site is in the Niles Cone Groundwater Basin, proximate to the San Francisco Bay and the large system of salt ponds present along the San Francisco Bay’s margin. Groundwater in the Niles Cone Groundwater Basin is known to experience saltwater intrusion, especially closer to the San Francisco Bay. Groundwater in the Niles Cone Groundwater Basin, including the Newark Aquifer, is considered to have beneficial use per the Basin Plan, regardless of total dissolved solids (TDS) concentrations. Concentrations of TDS detected in shallow groundwater at the Site have historically been as high as 3,160 milligrams per liter (mg/l) and generally exceed the Secondary MCL range for TDS of 500 mg/l (recommended) to 1,000 mg/l (upper). According to the Basin Plan, groundwater that contains TDS at a concentration exceeding 3,000 mg/l is not reasonably expected to supply a public water system. It is not anticipated that shallow groundwater beneath the Site would be used as a source of drinking water as part of a public water system. Shallow groundwater at the Site is contained in silt and sand zones within the Newark Aquiclude, which prevents significant migration of shallow groundwater into the Newark Aquifer below. Groundwater in the Newark aquifer is identified for beneficial uses including drinking water, but because of the presence of the Newark Aquiclude, Table 14

Description
impacts to shallow groundwater are unlikely to migrate to the Newark Aquifer. The down-gradient salt ponds and San Francisco Bay were identified approximately 100 feet southwest and 2.5 miles southwest of the Site, respectively, and it is unlikely that they have been impacted by historical releases at the Site because COCs were not detected at concentrations exceeding aquatic habitat ESLs in the down-gradient groundwater samples F-26, F-27, and F-28. The down-gradient water-supply well nearest the Site was identified approximately 1,600 feet southwest of the Site. Based on the distance to this well from the Site and the low concentrations of COCs detected in groundwater at the Site, it is highly unlikely that historical releases at the Site have impacted water-supply wells or have the potential to impact water-supply wells in the future.
For volatilization from soil or groundwater to indoor and outdoor air, the vapor inhalation pathway is considered incomplete. The concentrations of volatile COCs detected in shallow soil and groundwater at the Site were less than the commercial/industrial vapor intrusion human health risk level ESLs. In addition, cumulative vapor intrusion exposure risk and hazard were calculated by entering maximum concentrations of volatile COCs detected in samples collected from groundwater monitoring wells into the Tier 2 – Site-Specific Cumulative Risk and Hazard Calculator.3 Only COCs that contribute to vapor intrusion exposure risk and hazard were included in the risk assessment calculations. For example, DRO was detected in groundwater, but because it does not have a commercial/industrial vapor intrusion human health risk level ESL, it does not contribute to the calculation for cumulative vapor intrusion exposure risk and hazard, and was not included in the calculation of vapor intrusion exposure risk and hazard. A review of historical data collected at the Site found detections of four COCs that contribute to the calculation for cumulative vapor intrusion exposure risk and hazard: methyl ethyl ketone, methyl tertiary-butyl ether, benzo(a)anthracene, and naphthalene. The maximum detected concentration in groundwater monitoring well samples for each of the four COCs was entered into the calculation presented in Appendix F. Cumulative cancer risk and cumulative noncancer hazard due to vapor intrusion were 6.3E-09 and 1.5E-04, respectively, which are less than the cancer risk and noncancer hazard thresholds of 1.0E-6 and 1.0, respectively. Although no soil gas samples have been collected at the Site, the plethora of soil and groundwater samples with concentrations of volatile COCs less than commercial/industrial vapor intrusion human health risk level ESLs, and the cumulative cancer risk and noncancer hazard less than thresholds illustrate that subsurface conditions do not expose commercial workers to unacceptable health risks under continued commercial use.

1a) Pollutant sources are
identified and evaluated.
Former underground storage tanks (USTs) at the Site consisted of two 1,000-gallon USTs containing bunker fuel and gasoline and a 20,000-gallon diesel fuel aboveground storage tank (AST). The USTs, AST, and associated fuel islands and piping were removed from the Site between 1991 and 1993, stopping any releases that may have occurred. Visual inspection and soil sampling at the time of removal indicated that a release had not occurred from the two USTs. Soil and groundwater sampling at the time of the removal of the AST and associated fuel islands and piping indicated that a release had occurred.
1b) The Site is adequately
characterized.
The constituents of concern (COCs) at the Site in soil are total petroleum hydrocarbons (TPH) as diesel-range organics (DRO), TPH as oil-range organics (ORO), naphthalene, polycyclic aromatic hydrocarbons (PAHs), and metals. Only a single detection of arsenic that slightly exceeded the acceptable background concentration, and a detection of DRO that exceeded the San Francisco Bay Regional Water Quality Control Board (Water Board) commercial/industrial Environmental Screening Level (ESL) were reported in soil samples. The COCs at the Site in groundwater are: DRO, ORO, and PAHs. During the most recent groundwater monitoring event performed on March 2, 2023, detections of COCs in groundwater were less than the maximum contaminant levels (MCLs).

2b) Unacceptable risks to
human health, ecological
health, and sensitive
receptors, considering
current and future land
and water uses, are
mitigated.
A risk evaluation for potential receptors was conducted, and it was demonstrated that human health and the environment is protected:
• For direct contact with contaminated soil, the exposure pathways for incidental ingestion, dermal contact, and dust inhalation for commercial/industrial workers are considered complete; however, concentrations of COCs were less than commercial/industrial ESLs, with the exceptions of a single detection of arsenic that slightly exceeded the acceptable background concentration, and a single detection of DRO that exceeded the commercial/industrial ESL, which are considered low threat.
• Groundwater monitoring results from the most recent event on March 2, 2023 showed that COCs in groundwater samples collected from the Site are less than the MCLs, with concentrations decreasing from historical levels. The downgradient extent of the contaminant plume has been delineated by the off-Site down-gradient reconnaissance groundwater samples F-26, F-27, and F-28.
Groundwater in the Newark Aquifer is identified for beneficial uses including drinking water, but because of the presence of the Newark Aquiclude, impacts to shallow groundwater are unlikely to migrate to the Newark Aquifer. Down-gradient surface waters are highly unlikely to have been impacted because concentrations of COCs were not detected at concentrations exceeding aquatic habitat ESLs in the down-gradient groundwater samples F-26, F-27, and F-28. Due to the distance from the Site, groundwater supply wells are unlikely to have been impacted.
• For volatilization from soil or groundwater to indoor and outdoor air, the vapor inhalation pathway is considered incomplete; the concentrations of volatile COCs detected in shallow soil and groundwater at the Site were less than the commercial/industrial vapor intrusion human health risk level ESLs; and cumulative cancer risk and cumulative noncancer hazard due to vapor intrusion were 6.3E-09 and 1.5E-04, respectively, which are less than the cancer risk and noncancer hazard thresholds of 1.0E-6 and 1.0, respectively. 2c) Unacceptable threats
to groundwater and
surface water resources,
considering existing and
potential beneficial uses,
are mitigated.
Unacceptable threats to groundwater and surface water resources due to the release at the Site have been evaluated and found to be highly unlikely because detections of COCs in groundwater are less than the MCLs and aquatic habitat ESLs as of the most recent groundwater monitoring event performed on March 2, 2023.

PHOTOIONIZATION DETECTOR CALIBRATION AND OPERATION
PURPOSE AND APPLICATION
The purpose of this standard operating procedure (SOP) is to provide field personnel with the information needed to properly use, operate, and handle MiniRAE Photoionization Detector (PID) Models 2000 and 3000. The PID is used as a field-screening instrument for measurement of total volatile organic (TVO) concentrations in air. Typical uses include air monitoring of the breathing zone for health and safety purposes, screening of groundwater and soil for TVO emissions, and monitoring of the headspace of a monitoring well. The PID is a highly sensitive instrument.
MiniRAE Models 2000 and 3000 have a potential operating range of 0.1 to 15,000 parts per million (ppm) isobutylene equivalents, depending on the lamp used. The detection limit is 0.1 ppm hexane or isobutylene, with a response time of less than 3 seconds.
Operation and maintenance manuals specific to this equipment should be referenced as necessary.
Two user manuals are kept in Farallon’s PID case: the MiniRAE 3000 Pocket Reference; and the MiniRAE 3000 User’s Guide. These manuals should always be stored in the PID case so they are available for reference.
The step-by-step guidelines provided in this SOP are to be followed by the field crew when monitoring concentrations of TVO compounds in the breathing zone, a soil sample, a water sample, or the headspace of a monitoring well.
EQUIPMENT
The following equipment is necessary to calibrate and operate the PID:
• The PID instrument;
• A calibration gas regulator and silicon tubing;
• Calibration gas containing approximately 100 ppm isobutylene; and • A 110-volt battery charger.
PID CALIBRATION CHECK
PID calibration should be checked at the beginning of the day, and as needed if drift occurs (see “PID Drift or Other Change” section below). The instructions below are to be followed to check PID calibration (refer to pages 17 and 18 of the MiniRAE 3000 User’s Guide for information regarding the connection between buttons and control functions):
• Turn on the PID by pressing [MODE]. Wait for the PID to proceed to the default display, and allow the instrument to warm up for 10 minutes in accordance with the manufacturer’s instruction. The initial reading should be 0 or 0.1 part per million volume (ppmv). • Connect the regulator to the gas cylinder, and connect the tubing to the regulator.

2 G:\Manuals_Charts_Policies\Field Work SOPs\EQ_Equipment\EQ-02 PID Calibr and Operation 2018-05-10.docx Your Challenges. Our Priority. | farallonconsulting.com • Start the gas flow by pushing in the regulator knob and turning 90 degrees. Some gas will begin to escape.
• Connect the tubing from the regulator to the PID sensor tip. The PID reading should climb to 99 to 101 ppmv.
• When the PID reading reaches the maximum level displayed, turn off the regulator and disconnect the sensor tip. The reading should return to zero. • If any of the readings predicted above do not occur, re-calibrate the PID or arrange for repair.
PID CALIBRATION
The instructions below are to be followed to perform a zero (fresh air) calibration and a span calibration on the PID (refer to pages 35 through 46 of the MiniRAE 3000 User’s Guide for information regarding calibrations):
Zero Calibration (a zero calibration always should be performed prior to a span calibration):
• Turn the unit on by pressing [MODE] for approximately 1 second. • Press and hold [MODE] and [N/-] simultaneously until you see the Password Screen. • Input the password:
o The default password is 0000.
o Use the [Y/+] to increase the number value from 0 through 9. o Use the [N/-] to move the cursor to a different number slot. o Press [MODE] once you have input the password.
• Select “Calibration” by using [Y/+].
• Select “Zero Calib” by using [Y/+].
• Apply a fresh air source to the unit. Clean ambient air without detectable contaminants may be used as a fresh air source.
• Press [Y/+] to start the zero calibration. The zero calibration will take approximately 30 seconds to complete.
• The display screen will return to the Calibration menu when the zero calibration is complete.
• Record the values read by the PID in a calibration book or in the Log Field Book.
Once the zero calibration is complete, the unit automatically returns to the Calibration menu.
If the PID does not read 0.0 ppmv following the zero calibration, repeat the zero calibration procedure. If the PID fails both attempts to zero calibrate, move on to span calibration.

SPAN CALIBRATION
• Press [N/-] to scroll down to “Span Calib.”
• Press [Y/+] to select “Span Calib.”
• Select the proper calibration gas. Ensure that the calibration gas and the span value on the unit’s display screen have the same TVO concentration.
• Connect the regulator to the gas cylinder, and connect the tubing to the regulator. • Press [Y/+] to begin the span calibration.
• Immediately apply the correct calibration gas to the unit’s probe by turning the regulator knob 90º in either direction. The span calibration will take approximately 30 seconds. • The calibrated value should be +/- 2 percent of the concentration indicated on the calibration gas canister. Once the span calibration is complete, the unit will automatically return to the calibration menu.
• If the calibrated value is 2 percent greater than the concentration indicated on the calibration gas canister, repeat the span calibration procedure. • Press [MODE] twice to navigate back to the main display. • When calibrating the PID with isobutylene, record values read by the PID in a calibration book or in the Log Field Book.
• If the PID did not initially calibrate using the zero calibration mode, re-attempt to calibrate the PID using fresh air.
If the PID does not calibrate using the span calibration gas, call and update the Project Manager on the status.
PID DRIFT OR OTHER CHANGE
PID drift commonly is a failure of the instrument to return to zero after TVO concentrations dissipate. A failure to return to zero usually reflects inaccuracy at the upper end of the instrument’s detection range. Several situations can cause drift, including soil or water in the tip of the probe, soil or water in the sensor filter, or a change such as tightening or loosening the probe tip assembly since the instrument was last calibrated. The degree of drift from the initial daily calibration can be checked by exposing the PID to the calibration gas (see the “PID Calibration” section above).
Re-calibration serves little purpose until the cause of the drift is determined.
If you determine that PID drift is occurring, complete the following actions:
• Unscrew the probe from the PID unit;
• Inspect the probe and the top of the unit for soil or moisture; • Carefully remove any soil or moisture from the probe and/or unit by air drying; SOP EQ-02

4 G:\Manuals_Charts_Policies\Field Work SOPs\EQ_Equipment\EQ-02 PID Calibr and Operation 2018-05-10.docx Your Challenges. Our Priority. | farallonconsulting.com • Replace the sensor filter on the probe with a new, unused sensor filter; • Screw the probe back on the unit; and
• Apply Span Calibration gas to test the accuracy of the PID unit.
PID OPERATION
The instructions below are to be followed for PID use to screen soil and groundwater for TVO concentrations, to monitor the breathing zone for health and safety purposes, and to monitor monitoring well headspace:
• Connect the PID sample probe with filter to the PID hand-held air monitor. • Turn on the PID by pressing [MODE]. Wait for the PID to proceed to the default display, and allow the instrument to warm up for 10 minutes in accordance with the manufacturer’s instructions.
• CAUTION! Do not seal the soil in a plastic bag for longer than 5 minutes when conducting soil screening to avoid false readings due to moisture build-up (in wet situations, use the filter on the end of the sensor tip). Pierce the plastic bag with a clean tool, and immediately insert the sensor tip, quickly establishing a tight seal. The meter should react rapidly.
Record the maximum value displayed within 30 seconds.
• To monitor groundwater and soil for TVO emissions, place the probe inlet near the groundwater or soil surface, and read the meter display showing detected concentrations.
Do not allow water or soil to be sucked into the instrument. • To monitor the breathing zone for health and safety purposes, allow the PID to monitor air quality at the breathing zone, chest, or face level, and read the meter display showing detected concentrations.
• Monitor the headspace of a monitoring well directly after the well has been opened. Place the probe inlet directly above the polyvinyl chloride well casing or tubing that is associated with a dedicated pump in the well. Read the meter display showing detected concentrations. • Ensure that the PID is kept dry while in use. Humidity or moisture from rain can cause large fluctuations in PID readings, and can damage the instrument. • If the PID displays erratic readings, it is possible that either moisture or dirt is in the probe, or dirt has collected in the filter. If this occurs, clean and dry the sample probe (possibly by placing it near a running heater in a vehicle), and replace the filter if necessary.
DOCUMENTATION
Document the PID measurements for all monitoring events on field forms and in a detailed field notebook, and record observations of varying weather conditions such as temperature and humidity fluctuations.

GROUNDWATER LEVEL MEASUREMENT IN MONITORING WELLS
PURPOSE AND APPLICATION
The purpose of this standard operating procedure (SOP) is to provide field personnel with the methodology for measuring and documenting the depth to groundwater in monitoring wells. The step-by-step guidelines provided in this SOP are to be followed by the field crew to ensure consistent and representative measurements of depth to groundwater in monitoring wells. When multiple wells are present at a site, all water-level measurements typically are taken as quickly as possible to aid in the creation of potentiometric surface maps that are representative of a “single” point in time.
EQUIPMENT AND SUPPLIES/REAGENTS
The following equipment is necessary to properly measure the depth to groundwater in monitoring wells:
• Monitoring well key, hand drill, socket set, Allen wrench, speed handle, padlock key, or other monitoring well-access equipment specific to the monitoring well monument cover plate.
• Electronic water-level meter (Solinst or equivalent) narrow enough to fit in the monitoring well, calibrated to 0.01 foot, with sufficient line to reach the bottom of the monitoring well. • Oil-water interface probe, if light nonaqueous-phase liquid (LNAPL) is known or suspected to be present.
• Disposable bailer if LNAPL is known or suspected to be present, and the Project Manager requests that LNAPL be bailed from the well.
• Tape measure.
• Materials necessary to provide required documentation, including Groundwater Level Measurement Summary Forms and Field Report forms.
• Personal protective equipment as described in the site-specific Health and Safety Plan. • Decontamination equipment as specified in Farallon SOP EQ-01, Equipment Decontamination Procedures.
DECONTAMINATION
Before arrival at the site, upon relocation at the site, and upon demobilization from the site, decontaminate equipment that will come into contact with groundwater, in accordance with Farallon SOP EQ-01, Equipment Decontamination Procedures.

PROCEDURES
Follow the instructions below for measuring water levels at each monitoring well:
• Don appropriate personal protective equipment as described in the site-specific Health and Safety Plan.
• Check the operation of the water-level meter by turning on the indicator switch and pressing the test button.
• Remove soil or vegetation from the monitoring well site. • Open the monitoring well-head enclosure, and use a bilge pump or cup to remove standing water inside the monitoring well monument before opening the monitoring well cap.
Dispose of standing water to the ground surface.
• Open the monitoring well cap.
• Monitor air quality at the monitoring well-head if volatile contaminants are suspected to be present, or if it is unknown whether volatile contaminants are present. • Repeat above procedure until all monitoring wells are open. • Allow the water level to equilibrate with ambient atmospheric pressure for approximately 15 minutes before measuring.
• Before taking any measurements, carefully measure the length of the sonde to the nearest
0.01 foot. The additional 2 to 3 inches from the zero point of the sonde to the tip of the sonde must be discounted for all total depth measurements. • Measure and record the depth to water using a water-level meter that has been decontaminated in accordance with Farallon SOP EQ-01, Equipment Decontamination Procedures. With the water-level meter turned on to a medium level of sensitivity, slowly lower the meter into the monitoring well casing until it reaches the groundwater table. The probe will beep when it reaches the interface of the groundwater table (when the electronic circuit is first completed). Stop lowering the probe, hold the graduated water-level cable to the notch or mark on the northern side of the top of the monitoring well casing, and note the length measurement. Repeat this process to collect a second water-level measurement.
If the two readings differ by more than 0.01 foot, repeat the measurements until the readings stabilize. Repeat the process until three consecutive stabilized readings have been measured. Record the water-level measurement only in relation to the probe being lowered into the monitoring well, not as it is raised out of the monitoring well. If you cannot see the top of the monitoring well casing when the water level beeps, grasp the tape with your thumb and index finger exactly at the measuring point corresponding with the notch or mark at the top of the monitoring well casing. Slowly pull the cable out of the monitoring well and read the measurement. Repeat until readings stabilize. • Remove the cable from the monitoring well, and record the stabilized depth-to-water measurement on the Groundwater Level Measurement Summary Form to the nearest 0.01 foot.

Our Priority. | farallonconsulting.com • Measure the total monitoring well depth. NOTE: If groundwater samples are to be collected, measure the total monitoring well depth after all groundwater samples have been collected, to avoid resuspension of settled solids in the monitoring well, impacting the samples. If the monitoring well does not have a dedicated pump, lower the water-level indicator probe to the bottom of the monitoring well to measure the total depth of the monitoring well. Gently bounce the probe on the monitoring well bottom, and pull the slack in the cord to read the total monitoring well depth. Repeat three times to ensure that the monitoring well depth measurement is reproducible, and is representative of the true depth.
Note on the Groundwater Level Measurement Summary Form whether the bottom of the monitoring well is hard or soft.
• Remove the cable from the monitoring well, and record the monitoring well depth measurement on the Groundwater Level Measurement Summary Form to the nearest
0.01 foot.
• Decontaminate the water-level meter in accordance with Farallon SOP EQ-01, Equipment Decontamination Procedures.
• If the presence of LNAPL is suspected or if site conditions are unknown, check for the presence of LNAPL by one of two methods:
o Use of a bailer: Use a new 3-foot-long disposable bailer attached to a nylon rope.
Slowly lower the bailer until the bottom of the bailer is approximately 2 feet below the water surface. Slowly retrieve the bailer, and measure the product thickness using a tape measure. Record the information on the Groundwater Level Measurement Summary Form. Dispose of the bailer and product or wastewater in accordance with Farallon SOP WM-01, Field Handling of Investigation-Derived Waste.
o Use of an oil-water interface probe: Decontaminate the oil-water interface probe in accordance with Farallon SOP EQ-01, Equipment Decontamination Procedures.
With the oil-water interface probe meter turned on to a medium level of sensitivity, slowly lower the probe into the monitoring well casing until it reaches the top of the LNAPL. The probe will have a steady beep when it reaches the interface of the LNAPL (when the electronic circuit is first completed). Stop lowering the probe, hold the graduated oil-water interface cable to the notch or mark on the northern side of the top of the monitoring well casing, and note the length measurement.
Repeat this process to collect a second LNAPL measurement. If the two readings differ by more than 0.01 foot, repeat the measurements until the readings stabilize.
Repeat the process until three consecutive stabilized readings have been measured.
Record the depth to LNAPL measurement only in relation to the probe being lowered into the monitoring well, not as it is raised out of the monitoring well. If you cannot see the top of the monitoring well casing when the oil-water interface probe beeps, grasp the tape with your thumb and index finger exactly at the measuring point corresponding with the notch or mark at the top of the monitoring well casing.

LOW-FLOW GROUNDWATER SAMPLING PROCEDURES
PURPOSE AND APPLICATION
The purpose of this standard operating procedure (SOP) is to provide field personnel with the methodology for collecting and documenting groundwater samples from monitoring wells using U.S. Environmental Protection Agency (EPA) low-flow groundwater sampling procedures (EPA 1996, 2017) for chemical analysis to ensure consistent and representative sampling. The step-bystep guidelines provided in this SOP are to be followed by the field crew conducting groundwater sampling.
EQUIPMENT AND SUPPLIES/REAGENTS
The following equipment is necessary to properly purge and sample a monitoring well:
• Monitoring well key, hand drill, socket set, padlock key, or other monitoring well-access equipment.
• Electronic water-level meter long enough to reach the bottom of the monitoring well, calibrated to 0.01 foot. Alternatively, to measure for light nonaqueous-phase liquid thickness in addition to groundwater, use an oil-water interface probe. • Monitoring well purging and sampling equipment:
o Submersible pump (bladder or Grundfos): the pump, control box, and power source (typically a portable generator or a 12-volt battery); or o Peristaltic pump: the pump with pump head, silicone tubing, tubing connectors (as needed), and power source (typically a 12-volt battery). • Sample tubing of project- and site-specific type and length. • Bailer, if a pump is not used, or if light nonaqueous-phase liquid requires removal. • Sufficient number of 55-gallon drums, including lids, gaskets, and fasteners, to contain all purge water, unless other water-handling arrangements have been made. • Flow-through water-quality meter(s) to measure temperature, pH, specific conductivity, dissolved oxygen, oxidation-reduction potential (ORP), and turbidity. • Air-space monitoring equipment if required (photoionization detector or multi-gas meter). • Decontamination equipment and supplies (e.g., buckets, scrub brushes, deionized or distilled water, potable water, Liquinox detergent).
• Materials necessary to provide required documentation, (e.g., sample labels, Field Report forms, Low-Flow Well Purging and Sampling Data form, Chain of Custody form, Waste Inventory Tracking Sheet).

Our Priority. | farallonconsulting.com • Sample containers with the chemical preservatives appropriate for the samples, as described in project-specific plans, or as required by the analytical laboratory at a minimum.
• Personal protective equipment as described in the site-specific Health and Safety Plan (HASP).
• Sampling-support equipment (e.g., sample coolers, ice, bubble wrap, clear tape, duct tape, resealable plastic bags, garbage bags, paper towels, distilled water, nitrile gloves, shipping supplies).
• U.S. Department of Transportation-approved drum(s) for purge water, unless other water-handling arrangements have been made. Separate drums are needed for liquid and solid wastes (Refer to Farallon SOP WM-01, Field Handling of Investigation-Derived Waste). Liquid wastes should not be added to drums containing solid wastes.
DECONTAMINATION
Before arrival at the site, upon relocation at the site, and upon demobilization from the site, decontaminate reusable equipment that will come into contact with the monitoring well(s) and/or be used to acquire samples, in accordance with Farallon SOP EQ-01, Equipment Decontamination Procedures.
PROCEDURES FOR LOW-FLOW GROUNDWATER SAMPLING
Low-flow groundwater sampling procedures have been developed for monitoring wells with a dedicated pump (dedicated monitoring wells) and for monitoring wells without a dedicated pump (non-dedicated monitoring wells). Setup, purging, sample collection, and post-sampling procedures for dedicated and non-dedicated monitoring wells are presented below.
Setup
Setup procedures differ slightly for dedicated versus non-dedicated monitoring wells. Follow the instructions below for the monitoring wells as indicated:
• Calibrate the water-quality meter for the field parameters specified in the project-specific plans. At a minimum, collect temperature, pH, and specific conductivity during purging and prior to sampling. Record on the Field Report form the equipment calibration and maintenance performed. Decontaminate the water-quality meter between monitoring wells by rinsing with distilled or deionized water. Manage the rinsate water used in collecting these measurements in the same manner as for purge water, as defined in project-specific plans, and in accordance with Farallon SOP WM-01, Field Handling of InvestigationDerived Waste. • Don appropriate personal protective equipment as described in the site-specific HASP, including nitrile gloves for activities that might involve contact with groundwater or equipment. Change gloves between each monitoring well at a minimum, or when SOP GW-04

• Brush away soil and/or vegetation, and pump standing water away from the monitoring well opening. If necessary, place a plastic drop cloth around the monitoring well-head to prevent sampling equipment from contacting the ground surface. • Inspect the condition of the monitoring well (e.g., locked monitoring well cap, tightness of monitoring well cap, well-marked measuring point on casing, disturbance of surface casing, straightness of monitoring well casing, condition of concrete pad). Indicate the monitoring well condition on the Low-Flow Well Purging and Sampling Data form. • Open the monitoring well cap. If the site-specific HASP identifies organic compounds as potential contaminants of concern, screen the monitoring well headspace and the breathing zone headspace (if specified in the HASP) for organic vapors using the appropriate field monitoring instrument (e.g., photoionization detector, multi-gas meter). • Measure and record the depth to water using a decontaminated water-level meter in accordance with Farallon SOP GW-03, Groundwater Level Measurements in Monitoring Wells.
• If light nonaqueous-phase liquid may be present (see site-specific plans), obtain a sample from the monitoring well using a bailer (if a dedicated pump is not in use), as specified in Farallon SOP GW-03, Groundwater Level Measurements in Monitoring Wells.
Alternatively, measure free-floating product thickness using an oil-water interface probe. • Calculate the monitoring well casing volume as follows:
Monitoring well casing volume in gallons = (π*r2
)*h(7.48 gallons/cubic foot)
Where:
r = radius of the inside of the monitoring well casing in feet h = length of the water column in the monitoring well casing (i.e., the depth to the bottom of the monitoring well minus the depth to water, both measured from the mark at the top of the monitoring well casing), in feet • For monitoring wells with dedicated pumps and tubing: Set up a flow-through cell in preparation for purging. Connect dedicated tubing from the monitoring well to the flow-through cell. Set tubing and/or pump to the correct water depth in accordance with the constituents being sampled for, as described in project-specific plans. DO NOT IMMERSE water-quality probes or meters in purge water containing nonaqueous-phase liquids, which could damage the probes. Turn the pump controller to its lowest setting, set the memory in the flow-through cell to record readings every 3 minutes, and turn on the pump. Begin purging slowly (i.e., less than 500 milliliters per minute [ml/min]) to prevent drawing down the water table.

Revision: May 2018
4 G:\Manuals_Charts_Policies\Field Work SOPs\GW_Groundwater\GW-04 Low-Flow Groundwater Sampling 2018-05.docx Your Challenges. Our Priority. | farallonconsulting.com • For monitoring wells with non-dedicated pumps: Connect dedicated silicon tubing to the peristaltic pump. Place the tubing intake at the midpoint of the screen, or at the depth pre-determined in the project-specific plans. If using a bladder pump, insert the bladder pump and attach the dedicated polyethylene tubing so the pump intake is at the approximate midpoint of the screened interval, or set the pump intake to the depth pre-determined in the project-specific plans.
Purging Procedures
The purging instructions below are to be followed for dedicated and non-dedicated monitoring wells:
• Begin purging, and initiate water-quality testing for temperature, pH, specific conductivity, dissolved oxygen, ORP, and turbidity. Purge monitoring wells using a peristaltic or bladder pump, and dedicated polyethylene and silicon tubing. Record water-quality parameters every 3 minutes.
• Record water levels every 3 minutes, as possible. It is imperative that the water level not drop by more than 0.33 foot during the low-flow purging process. If the water level drops more than 0.33 foot during purging, reduce the flow rate on the pump. Recommended purge rates generally are less than 500 ml/min. Actual purge rates will vary based on aquifer material and monitoring well construction. If the water level continues to drop by more than 0.33 foot during the low-flow purging at a rate less than 100 ml/min, notify and consult with the Project Manager on how to proceed.
• Record flow rates every 3 minutes. Ensure that the flow rate does not exceed 500 ml/min during the low-flow purging process.
Purging Requirements
Continue purging at a constant rate until the water-quality parameters have stabilized for three successive measurements according to the stability criteria provided in the table below. Before samples can be collected from each monitoring well, the groundwater must stabilize according to following criteria:
• Drawdown is no greater than 0.33 foot for low-flow sampling, and • The water-quality parameters should stabilize according to the criteria specified below:
SOP GW-04
Revision: May 2018
5 G:\Manuals_Charts_Policies\Field Work SOPs\GW_Groundwater\GW-04 Low-Flow Groundwater Sampling 2018-05.docx Your Challenges. Our Priority. | farallonconsulting.com Water-Quality Parameter Stability Criterion
Turbidity (if required) 10% for values greater than 5 NTU or three consecutive values < 5 NTU
Dissolved oxygen 10% for values greater than 0.5 mg/l, or three consecutive values <0.5 mg/l
Specific conductivity 3%
Oxidation-reduction potential +/- 10 millivolts
pH +/- 0.1 unit
Temperature 3%
Notes:
mg/l = milligrams per liter
NTU = nephelometric turbidity unit
Although under some circumstances, a monitoring well may not stabilize according to the above criteria, the monitoring well can still be sampled if the monitoring well does not meet stability criteria due to the instrument accuracy, or the water level drops below the minimum value using low-flow sampling procedures. For example, a fluctuation in ORP greater than 10 millivolts does not meet the stability criterion. However, because the accuracy range of the ORP instrument is ±20 millivolt, the stability criterion would be considered satisfied and within the range of instrument accuracy. Consult the manual for the instrument to determine the accuracy range.
Also, if the water level drops below the minimum value using low-flow sampling procedures (i.e., the pump intake, or the top of the screen if the aquifer is confined) during purging and one monitoring well volume of groundwater has been removed from the monitoring well, or the monitoring well runs dry during the purging procedure, sample the monitoring well as soon as the water level has recovered sufficiently to allow collection of the volume of groundwater necessary for all samples. Use the following equation to determine the minimum volume of groundwater to remove before sampling:
Minimum purge volume = 2*[500 milliliters + M*(length of tubing in feet)] Where: M = volume (in milliliters) contained in a 1-foot length of tubing The value of M is provided below for the inner diameters of tubing listed:
Inner Diameter (inches) M (milliliters)
0.125 2.4
0.25 9.7
0.5 39
Record on the Field Report form and the Low-Flow Well Purging and Sampling Data form if any monitoring well did not meet the drawdown and stability criteria and explain the rationale for sampling the monitoring well at the time it was sampled. If stability criteria have not been achieved following completion of all entries in the Low-Flow Well Purging and Sampling Data form, notify SOP GW-04

Our Priority. | farallonconsulting.com and consult with the Project Manager whether to continue purging until stability criteria have been achieved or begin sample collection.
Sample Collection
During low-flow sampling, do not stop pumping once the purging requirements have been met.
Turn down the flow rate on the pump so the water flow is minimal, but maintain sufficient pressure in the system to prevent water from the tubing or flow-through cell from flowing back into the monitoring well. Disconnect the pump discharge hose from the flow-through cell, or cut the tubing just before the connection to the flow-through cell. It is imperative not to lower the water table or disturb the water column. Fill pre-cleaned laboratory-supplied sample containers directly from the pump discharge tube into the proper sample container, and fill to capacity. Place a bucket beneath the sampling tube to catch any unsampled water between filling the sample jars. When collecting groundwater samples for multiple analyses, collect the samples in the order listed below per the EPA (1992) groundwater sampling technical guidance:
• Volatile organic compounds (VOCs);
• Dissolved gases and total organic carbon;
• Semivolatile organic compounds;
• Metals and cyanide;
• Major water quality cations and anions;
• Radionuclides; and
• Dissolved (filtered) inorganics (if required).
When collecting samples for VOCs, adjust the flow rate as low as possible without introducing air bubbles into the system. When filling the VOC containers, hold the cap in hand to minimize contamination, and direct the flow from the pump discharge tubing down the side of the sample container to minimize aeration. Fill all VOC sample containers to the top, ensuring a positive meniscus when the cap is screwed down on the container. Tap the filled VOC container, and invert several times to ensure no air bubbles are present in the sample container. If an air bubble is present, the VOC sample must be recollected using a fresh VOC sample container. If sampling for other analytes, the flow rate may be increased.
If dissolved inorganics are required, attach a new disposable 0.45-micrometer filter cartridge to the discharge line. Collect filtered samples last. Pre-rinse the disposable filter cartridges by running a minimum of 0.25 gallon of groundwater through them (collecting the groundwater into a waste bucket) prior to collecting the samples directly into the sample container. Alternate field filtration methods may be specified in the project-specific plans. Remove the pump and/or tubing from the monitoring well.

• Record the depth to water of well to determine whether the water level changed from the original reading.
• Close and lock the monitoring well or tap and record any monitoring well integrity concerns on the Field Report form and the Low-Flow Well Purging and Sampling Data form.
• Transfer purge, wash, and rinse water into a U.S. Department of Transportation-approved drum(s) and label. Separate drums are needed for liquid and solid wastes, in accordance with SOP WM-01, Field Handling of Investigation-Derived Waste. Do not add liquid wastes to drums containing solid wastes.
PROCEDURES FOR RECONNAISSANCE GROUNDWATER SAMPLING
Collect reconnaissance groundwater samples from borings using direct-push or hollow-stem auger drilling methods and 0.75- or 2-inch-inside-diameter temporary monitoring well casing and 0.010- inch slotted screen. In some cases, alternate well casing diameters or screen slot sizes may be appropriate based on the drilling equipment or project-specific requirements. Follow the instructions below for reconnaissance groundwater sample collection:
• Withdraw the drill casing when the desired sampling depth has been reached, so the temporary monitoring well screen is exposed to water-bearing material. • Insert disposable polyethylene tubing to the approximate midpoint of the temporary monitoring well screen. Attach the appropriate length of pre-cleaned disposable silicon tubing from the polyethylene tubing to connect with the peristaltic or bladder pump. • Set up the peristaltic or bladder pump in preparation for purging. Turn the pump to its lowest setting and turn on the pump. Begin purging slowly to prevent drawing down the water table.
• Purge each temporary monitoring well point using a peristaltic or bladder pump until visual turbidity is as low as possible, or until the temporary monitoring well is purged dry of water.
• Purge a minimum of 1 to 2 liters before sample collection, if possible. If the temporary monitoring well is completely dewatered during purging, collect samples when sufficient recharge has occurred to allow filling of the sample containers. • Slow the pumping rate to less than 500 ml/min to reduce the potential for volatilization of chemicals during sample collection.
• Collect the sample as described above.
• If insufficient groundwater is available to collect a sample using a peristaltic or bladder pump (i.e., the boring pumps dry or cannot maintain a sufficient flow of less than 100 ml/min) or if the depth to groundwater exceeds the maximum practicable limit for sampling using a peristaltic or bladder pump, use a disposable polyethylene bailer lowered SOP GW-04
