EXECUTIVE SUMMARY

DESCRIPTION
Environmental Data Resources, Inc.’s (EDR) City Directory Abstract is a screening tool designed to assist environmental professionals in evaluating potential liability on a target property resulting from past activities.

EDR’s City Directory Abstract includes a search and abstract of available city directory data. For each address, the directory lists the name of the corresponding occupant at five year intervals.

Business directories including city, cross reference and telephone directories were reviewed, if available, at approximately five year intervals for the years spanning 1920 through 2017. This report compiles information gathered in this review by geocoding the latitude and longitude of properties identified and gathering information about properties within 660 feet of the target property.

A summary of the information obtained is provided in the text of this report.

RECORD SOURCES
EDR's Digital Archive combines historical directory listings from sources such as Cole Information and Dun & Bradstreet. These standard sources of property information complement and enhance each other to provide a more comprehensive report.

EDR is licensed to reproduce certain City Directory works by the copyright holders of those works. The purchaser of this EDR City Directory Report may include it in report(s) delivered to a customer. Reproduction of City Directories without permission of the publisher or licensed vendor may be a violation of copyright.

PHASE II ENVIRONMENTAL SITE ASSESSMENT
We are pleased to submit this phase II environmental site assessment (ESA) for soil, groundwater, and soil gas characterization at the subject property (Property), located at 38600 Cedar Boulevard in Newark, California (Figure 1).

BACKGROUND
The Property is approximately 3.5 acres in area and consists of two parcels identified with Assessor’s Parcel Numbers (APNs) 92A-2585-12-1 and 92A-2585-31. The Property is an open Leaking Underground Storage Tank (LUST) case with the Alameda County Water District (ACWD) and the San Francisco Bay Regional Water Quality Control Board (RWQCB); Nortrax West (T0600100516).

The Property is designated as medium density residential under the City’s current general plan, permitting 14 to 30 homes per net acre. The proposed development is consistent with the City’s housing element and provides seventy-six (76) three-story townhomes at an approximate density of 20 homes per acre designing around and accommodating the many existing underground utilities in their current location.

This assessment was performed to address remaining impediments to closure and future development, which included additional soil, groundwater, and soil gas testing near the former underground storage tanks (USTs, Figure 2). Further sampling of the existing eight groundwater monitoring wells was also part of the scope.

BACKGROUND
Nortrax West (GeoTracker case ID T0600100516) is the open cleanup case pertaining to the Property. The Property has been occupied by various construction and agricultural equipment rental, sales, and/or repair businesses throughout its history. The first known tenant was International Harvester Company. The site was purchased by the Horton family in the 1970s.

Between 1975 and 1979, the western warehouse was constructed. Horton Equipment Company operated at the Property until 1985, at which time Empire Tractor and Equipment Company began leasing the site. Nortrax purchased Empire in 2001 and were subsequently purchased by Papé Machinery in 2005, which remains the current tenant.

The following summarizes relevant past documentation and reports associated with the Property.

One 10,000-gallon diesel underground storage tank (UST), one 10,000-gallon gasoline UST, and two 550-gallon diesel USTs were formerly located in the eastern area of the 38683 Timber Street parcel. A former 550-gallon waste oil tank was located in the southern area of the parcel, south of the building, near Cedar Boulevard. The 10,000-gallon gasoline UST, 10,000-gallon diesel UST, 550-gallon diesel UST, and 550-gallon waste oil tank were known to exist when the Property was purchased by the current owner in the 1970s. An additional 500-gallon diesel UST was discovered during the UST removal in 1989. Four groundwater monitoring wells (MW-1 through MW-4) were first installed in the vicinity of the known fuel USTs in 1986, in accordance with ACWD regulations for USTs. Soil samples were collected from the unsaturated zone at depths targeted near the bottom of each nearest UST (7 to 13 feet bgs). This initial sampling did not detect total petroleum hydrocarbons (TPH) above laboratory reporting limits.

A semi-annual groundwater monitoring event in March 1988 did not indicate significant concentrations of TPH or VOCs. However, a subsequent semi-annual groundwater monitoring event conducted in October 1988 reported 1/16th inch of light non-aqueous phase liquid, reportedly diesel, in the sample collected from MW-2. The sample from MW-2 had a concentration of 230,000 μg/L of TPH as gasoline (TPH-g). An UST release report was filed by the Newark Fire Department with ACWD. The 500-gallon diesel UST was ordered to be emptied immediately and removed. All USTs were removed from the site in April 1989 under oversight of the Fire Department and ACWD. During tank excavations and removals, the additional 500-gallon diesel UST was discovered. In total, five tanks were removed, and visibly contaminated soil was excavated for disposal (Ramboll, 2016).

Quarterly groundwater monitoring was conducted intermittently between 1991 and 1993, 1997 and 1998, and in 2001, which indicated that contamination was not sufficiently remediated.

According to the site history section on GeoTracker, TPH-g was detected in groundwater at concentrations up to 4,300 μg/L in 1992. In 1993, total petroleum hydrocarbons as diesel (TPH-d) were detected in groundwater in concentrations up to 120,000 μg/L. Methyl tert-butyl ether (MTBE) was either non-detect or detected at very low levels in soil and groundwater.

Chlorinated volatile organic compounds (VOCs) were also detected onsite. Tetrachloroethylene (PCE) was detected in groundwater at a concentration of 160 μg/L; 1,1-trichloroethane (TCA) was detected up to 180 μg/L; and 1,1, -Dichloroethane (DCA) was detected up to 57 μg/L (Ramboll, 2016).

Hydro Analysis, Report of Subsurface Investigation, Nortrax West, 38600 Cedar Boulevard, Newark, California; November 16, 2004.

Hydro Analysis, Inc. conducted an investigation in 2004 to delineate the horizontal and vertical extent of groundwater impacts and to potentially install additional groundwater monitoring wells.

Fourteen borings were installed on site and downgradient to the south of the site to depths of 20 feet bgs. Soil samples were collected at 5 and 10 feet in the borings and 15 feet in select borings. All soil samples were analyzed for TPH, BTEX, and MTBE. Select samples were analyzed for VOCs. Grab groundwater samples were collected at each location and analyzed for TPH, BTEX, MTBE, and VOCs. Two deeper groundwater samples were collected at 55 to 60 feet bgs from CPT locations and analyzed for TPH, BTEX, MTBE, and VOCs. Results of the soil sampling in the vicinity of the former fuel UST cluster reported low concentrations of TPH-g and TPH-d in shallow samples and low concentrations of BTEX in the 5 feet bgs sample.

sampling in the vicinity of the former waste oil UST reported low concentrations of TPH and BTEX. Downgradient soil samples did not report TPH or BTEX above reporting limits. Low concentrations of PCE were reported in deeper samples in the vicinity of the former waste oil UST. 1,1-DCA was detected in the 15 feet bgs sample. The only exceedance of regulatory screening criteria for all soil samples was the concentration of TPH-d in the 5 feet bgs sample.

Results of groundwater samples reported low concentrations of TPH-d in the vicinity of the former fuel UST cluster. Low concentrations of TPH, BTEX, and VOCs were also detected in samples collected in the vicinity and downgradient of the former waste oil UST. In general, concentrations of TPH and VOCs were consistent with those reported during periodic groundwater monitoring events at the site. TPH, MTBE, BTEX, or VOCs were not detected in deep groundwater samples from the Newark Aquifer.

Hydro Analysis, Report of Subsurface Investigation, Nortrax West, 38600 Cedar Boulevard, Newark, California; November 30, 2007.

A 2007 monitoring well installation was performed at the request of ACWD to determine the lateral extent of the VOC contamination. Four additional monitoring wells were installed at the site upgradient, cross gradient, and downgradient of the former waste oil UST. Soil samples were collected at 5-foot intervals to 20 feet bgs and analyzed for TPH, BTEX, MTBE, and VOCs. No concentrations of TPH or BTEX were detected in soil samples with the exception of one low TPH-d concentration. Low VOC concentrations were detected at two of the locations.

No concentrations of TPHs or VOCs were above regulatory screening criteria. Groundwater sampling indicated low concentrations of TPH-d in two well locations and no other TPH, BTEX, or MTBE above reporting limits within the remaining. All four monitoring wells had at least one detection of a VOC, including low concentrations of PCE, 1,1,1-TCA, TCE, 1,1-DCA, and cis-1,2-DCE. PCE was detected in all four monitoring wells (Ramboll, 2016).

TRC; First Semi-Annual 2018 Groundwater Monitoring Report; 38600 Cedar Boulevard, Newark, California; June 22, 2018
The TRC report documents groundwater sampling performed in the summer of 2018.

Groundwater monitoring was performed for wells MW-1 through MW-8. For wells MW-2 and MW-4, located in the upgradient portion of the site, analyses detected no TPH-g, benzene, ethylbenzene, xylenes, MTBE, or naphthalene. With the exception of one detection of TPH-d at 2,400 μg/L in MW-3, analyses detected no analytes exceeding respective MCLs.

Wells MW-1 and MW-5 through MW-8 are located in the downgradient portion of the Site. With the exception of 170 μg/L of TPH-mo at MW-1, analyses detected no concentrations of TPH-g, TPH-d, TPH-mo, BTEX, MTBE, or naphthalene in any of the downgradient wells.

Stantec, Documentation of Shallow Soil Sample Collection and Soil Vapor Sampling; 38600 Cedar Boulevard; Newark, California; October 18, 2018 Based on ACWD direction, Stantec attempted to redevelop three wells, MW-1 through MW-3.

Only MW-2 was able to be redeveloped because MW-1 and MW-3 had bends in the wells. At the time of the report, Stantec was in discussion with ACWD to determine a path forward to repairing and redeveloping the damaged wells. One soil sample was obtained at 10 feet bgs.

PCE was detected at 0.023 mg/kg. No VOCs, TPHs, or PAHs were detected. One soil vapor well was installed at the same location and analyzed for VOCs and helium. 1,1-DCE, carbon disulfide, 1,1-DCA, cis-1,2-DCE, 1,1,1-TCA, TCE, and PCE were detected. 1,1-DCA, TCE, and Packet Page 2203

PCE were detected above their respective ESLs.

Stantec proposed to install six additional soil vapor wells and the redevelopment of monitoring wells MW-1 and MW-3.

ENGEO, Phase II Environmental Site Assessment, 38600 Cedar Boulevard, Newark, California, August 28, 2020; Project No. 15799.001.000.

ENGEO conducted a phase II environmental site assessment in August 2020 to further address subsurface impacts, which included additional soil and soil gas testing near the former waste oil UST, further delineation of soil vapor impacts, and assessment and sampling of the existing eight monitoring wells.

Soil sampling included collection of a total of 16 samples from four boring locations at depths of 1, 5, 10, and 15 feet bgs. The samples were analyzed for TPH-g, VOCs, TPH-d, TPH-mo, and metals.

Grab groundwater sampling included collection of three samples from the five attempted boring locations (GW-1 through GW-5). Locations GW-3 and GW-5 did not exhibit sufficient recharge during sample collection. The three samples were analyzed for TPH-g, VOCs, TPH-d, and TPH-mo. Monitoring wells MW-1 through MW-7 were sampled and submitted for the same analyses as the grab groundwater samples.

Thirteen soil gas wells were also installed on the Property. Seven wells were installed as nested wells near the former waste oil tank at depths of 6 and 10 feet bgs and the remaining six soil vapor probes were installed to 6 feet bgs.

The soil samples exhibited detections of chromium, lead, nickel, and zinc. TPH-g, TPH-d, and TPH-mo were detected in various samples. One VOC, tert-butanol, was detected in three samples. All concentrations were below SFBRWQCB residential ESLs, with the exception of TPH-d.

The grab groundwater samples contained low concentrations of VOCs including PCE, TCE, cis-1, 2-DCE, 1,1-DCA, and isopropyl benzene, at concentrations below RWQCB Priority Maximum Contaminant Levels (MCLs). TPH was not detected above laboratory reporting limits.

The monitoring well samples contained low concentrations of VOCs including PCE, TCE, cis-1,2-DCE, 1,1-DCE, vinyl chloride, 1,1-DCA, and 1,1,1-trichloroethane. MW-1 exhibited exceedances of PCE, TCE, cis-1,2-DCE, vinyl chloride, and 1,1-DCA, with respect to MCLs.

PCE was additionally reported in exceedance of its screening levels in MW-7.

Cis-1,2-dichloroethene was reported in exceedance of its MCL screening level in MW-7. TPH-g was reported at 209 μg/L in MW-1, below the MCL. Minor concentrations of TPH-d were reported in MW-2 and MW-3, both below the MCL. TPH-mo was not detected above laboratory reporting limits in any samples. Groundwater impacts appear to be localized to the immediate vicinity of the former waste oil tank and continue to attenuate based on historical monitoring events.

The soil gas samples exhibited various VOC detections. PCE, TCE, cis-DCE, and vinyl chloride were detected in a majority of the samples. PCE was in exceedance of RWQCB residential ESLs1in all except one sample (SG-10), at concentrations ranging between 27 and 36,000 micrograms per cubic meter (μg/m3). TCE was in exceedance of ESLs for sample locations SG-2@6’, SG-2@10’, SG-3@10’, SG-4@6’, SG-4@10’, SG-5@6’, and SG-5@10’, at concentrations ranging between 35 and 6,600 μg/m3. Cis-1,2-DCE was reported in exceedance of its ESL at SG-4@10’, SG-5@6’, and SG-5@10’, at concentrations ranging between 7,000 and 33,000 μg/m3. Vinyl chloride was reported in exceedance of its ESL at SG-5@6’ (1,900 μg/m3) and SG-5@10’ (2,000 μg/m3). Other VOCs detected in samples exceeding ESLs included 1,1,2-trichloroethane, 1,1-DCA, benzene, carbon tetrachloride, chloroform, and naphthalene. TPH-g was reported in exceedance of its ESL for SG-1@6’, SG-1@10’, SG-2@10’, SG-3@6’, SG-4@10’, SG-5@6’ and SG-5@10’. Overall, soil gas impacts appear to the most concentrated in the vicinity of the former waste oil UST. Tables A through D provide a summary of the 2020 ENGEO data results.

ACWD - Request for Soil Gas Investigation, September 22, 2021.

In a September 2021 letter to Ohana Land Company, LLC (former Property owner), ACWD requested that an additional soil vapor and indoor air investigation be conducted. ACWD cited the soil gas results of ENGEO’s previous phase II investigation, noting that the elevated VOC concentrations may pose a risk to human health. ACWD noted that the extent of VOC contamination in soil vapor should be defined onsite and offsite, and any potential vapor intrusion to indoor air pathways should be evaluated. Depending on the results of the investigation, a Corrective Action Plan to remediate and/or mitigate the soil vapor impact may be required.

ENGEO, Supplemental Environmental Assessment Work Plan, 38600 Cedar Boulevard, Newark, California; November 23, 2021 (Revised March 3, 2022). Project No. 15799.002.000.

ENGEO prepared a work plan to address remaining impediments to closure as part of ACWD’s request. The following scope of work was proposed.
• Collection of soil gas samples from the existing 14 soil gas wells SV-1 and SG-1 through SG-13 for analysis of VOCs.
• Installation of eight additional permanent soil gas wells on the Property, including six on-site and two off-site along the southern side of Cedar Boulevard for analysis of VOCs. • Collection of groundwater samples from monitoring wells MW-1 through MW-7 for analysis of TPH-g, VOCs, TPH-d, and TPH-mo (wells MW-8 could not be located and appeared to have been buried or damaged due to recent City of Newark landscape and sidewalk improvements).
2022 FIELD EXPLORATIONS
Additional drilling and sampling events took place in 2022 on July 13, July 15, August 5, August 23, and August 26. Prior to drilling, an ENGEO representative contacted the USA North Service Alert in addition to a private utility locator to facilitate notification to operators of 1 San Francisco Bay Regional Water Quality Control Board ESLs for Subslab/ Soil Gas Vapor Intrusion ESL Levels, Residential (Interim Final 2019, Rev 1).

underground utilities at the Property. Drilling activities were performed by a C-57-licensed drilling contractor, utilizing Geoprobe® direct-push technology. All work was performed by an ENGEO environmental professional under the supervision of a registered professional engineer.

See attached figure for sample locations (Figure 2).

Monitoring Well Sampling
Monitoring wells were sampled during the 2022 exploration. Monitoring wells MW-1 through MW-7 were purged of three well casing volumes and sampled using a peristaltic pump.

Groundwater parameters were measured during purging to verify stabilization. MW-8 could not be located and has been buried or damaged due to recent City of Newark landscape and sidewalk improvements. The groundwater samples were then placed in laboratory-provided sample containers and submitted to Torrent Laboratory, Inc., for analysis of the following. • TPH-g and VOCs (EPA Method 8260)
• TPH-d and TPH-mo (EPA Method 8015)
Soil Gas Sampling
The nine soil gas wells and the re-install of SG-10 were installed as shown on Figures 2 and 3.

All 10 soil gas wells were installed to 6 feet below the ground surface. Twenty-seven total soil gas samples were collected. SG-2@10’ was not able to be recovered as the well was destroyed.

All of the soil gas samples were recovered in accordance with Department of Toxic Substances Control (DTSC) Final Advisory Active Soil Gas Investigations (July 2015). The general sampling procedures are described as follows:
• The soil gas monitoring probes consisted of ¼-inch-diameter Teflon® tubing equipped with a filter at the base of tubing. Soil gas wells were installed with a direct-push rig, which was advanced with an approximately 2.5-inch-diameter boring, then were hand augered to a diameter of 4.5 inches. The well borings extended to a depth of 6 and 10 feet below the ground surface (bgs) for the wells installed in 2020 and 6 feet bgs for the wells installed in 2022, with a 1-foot sand layer at the base. A 2-inch bentonite seal surrounded the tubing within the well boring.
• After the 48-hour equilibration time elapsed, soil gas samples were collected from the wells.

The sample train was connected to the well tubing by threading the permanent Swagelok® fitting on the well casing onto the manifold. The sample train consisted of a stainless-steel twin SUMMA manifold with a built-in flow controller set to 150 milliliters per minute (ml/min). • Prior to connecting the sample train to the well casing, a shut-in test was performed to assess for potential leaks. The shut-in test consisted of capping the end of the manifold, then applying a vacuum with the purge canister, closing the purge valve, and observing the vacuum gauge for 2 minutes to determine if there was a drop in vacuum. • Once the sample train was connected to the well casing, three well volumes of soil gas were purged from each well prior to sampling at a flow rate of 150 ml/min. After purging was completed, the purge valve on the manifold was closed and the vacuum canister removed.

Samples were collected by opening the sample canister valve and allowing the sample canister to extract soil gas until the vacuum in the sample canister reached approximately Packet Page 2206

5 inches of mercury. The leak detection compound 1,1-difluoroethane (1,1-DFA) was applied by wrapping a doused rag around the manifold fittings during sample collection. • Sample canisters were labeled with a unique identification number, sampling time, and/or pre- and post-sample vacuum readings. The soil gas samples were submitted to Torrent Laboratory, Inc., for analysis of TPH-g (EPA Method TO-3M), VOCs (EPA Test Method TO-15), and fixed gases (ASTM D-1946) for the samples collected in 2020. The samples collected in 2022 were analyzed for VOCs (EPA Test Method TO-15), and the newly installed wells were tested for fixed gases (ASTM D-1946). • Soil gas wells were retained at the Property. A flush-mount well box was installed at the ground surface for each of the wells.

Monitoring Well Sampling Results
The 2022 monitoring well samples contained low concentrations of VOCs, including PCE, TCE, and cis-1,2-DCE, 1,1-DCA, and 1,1,1-trichloroethane (1,1,1-TCA). Both MW-1 and MW-7 exhibited exceedances of PCE and cis-1,2-DCE with respect to MCLs.

TPH-g was reported at 136 micrograms per liter (µg/L) in 2022, below the applicable ESL. Minor concentrations of TPH-d were reported in MW-6 and MW-7, both below the MCL. TPH-mo was not detected above laboratory reporting limits.

We were unable to locate MW-8 during our field explorations in both 2020 and in 2022; however, previous sampling data indicates MW-8 has not exhibited concentrations above MCLs and is stable. A summary of well sample results is provided in Table C. Laboratory results are presented in Appendix A.

Soil Gas Sampling Results
Review of the soil gas results found detectable VOCs in all of the 19 samples. Chlorinated hydrocarbons PCE, TCE, cis-1,2-dichloroethene (cis-1,2-DCE), chloromethane, chloroethane, 1,1,1-trichloroethane, 1,1-dichloroethane, 1,2,4-trichlorobenzene, 1,1,2-trichloroethane (1,1-DCA), carbon tetrachloride, vinyl chloride, benzene, chloroform, ethyl benzene, and hexachlorobutadiene were detected in all but one sample. Samples with residential ESL exceedances are shown in Table B.

FINDINGS AND CONCLUSIONS
Soil Samples
Previous soil sampling conducted at the Property have not identified residual soil impacts of significance. No soil mitigation appears necessary for the Property; however, we anticipate a Soil Management Plan (SMP) will be prepared for future site development to address potential unforeseen subsurface impacts.

Grab Groundwater Samples
The 2020 grab groundwater samples did not exhibit TPH-g, TPH-d, TPH-mo, or VOCs in exceedance of RWQCB ESL MCLs. Monitoring wells MW-1 and MW-7, both within the vicinity of the former waste oil UST, exhibited concentrations of PCE above the MCL (5 µg/L) at Packet Page 2207

concentrations of 61 and 10 µg/L, respectively. TCE, cis-1,2-DCE, vinyl chloride, and 1,1-DCA were also detected in concentrations exceeding MCLs for MW-1. cis-1,2-DCE was detected above the MCL for MW-7. We were unable to locate MW-8 to further assess downgradient impacts; however, PCE, the primary constituent of concern, was reported at 2 µg/L in TRC’s 2018 monitoring event, below the MCL, at MW-8. Impacts appear to be localized to the immediate vicinity of the former waste oil tank and continue to attenuate.

Monitoring Well Samples
The 2022 groundwater samples did not exhibit TPH-g, TPH-d, TPH-mo, or VOCs in exceedance of RWQCB ESL MCLs. Monitoring wells MW-1 and MW-7, both within the vicinity of the former waste oil UST, exhibited concentrations of PCE above the MCL (5 µg/L) at concentrations of 61 and 10 µg/L, respectively. TCE, cis-1,2-DCE, vinyl chloride, and 1,1-DCA were also detected in concentrations exceeding MCLs for MW-1. cis-1,2-DCE was detected above the MCL for MW-7. We were unable to locate MW-8 to further assess downgradient impacts; however, PCE, the primary constituent of concern, was reported at 2 µg/L in TRC’s 2018 monitoring event, below the MCL, at MW-8. Impacts appear to be localized to the immediate vicinity of the former waste oil tank and continue to attenuate based on historic monitoring events. Figure 3 provides the approximate area of residual impacts based on PCE concentrations above MCLs. No further groundwater monitoring is recommended for the Property.

Soil Gas Samples
Numerous VOCs were detected in soil gas samples exceeding ESLs including tetrachloroethylene (PCE), trichloroethylene (TCE), vinyl chloride, 1,1-dichloroethane, 1,1,2-trichloroethane (1,1-DCA), 1,2,4-trichlorobenzene, cis-1,2-dichloroethene (Cis-1,2-DCE), benzene, chloroform, ethyl benzene, and hexachlorobutadiene. Elevated concentrations of PCE were detected in 23 of the 27 samples.

These impacts appear to the most concentrated in the vicinity of the former waste oil UST, and there is some evidence of reductive de-chlorination occurring within the plume. Figure 3 provides an approximation of soil vapor plume, based on the data available, for PCE concentrations in exceedance of ESLs.

RECOMMENDATIONS
Former Leaking Underground Tank (LUST) Closure
The area of the former diesel/gasoline fuel tank area in the southeastern area of the Property appears to meet applicable RWQCB Low Threat Closure Policy criteria, as the source has been removed and groundwater concentrations are stable/decreasing. No additional monitoring or mitigation appears necessary for petroleum-related constituents; however, elevated PCE has been detected in soil gas within this area (SG-11), which may require further assessment and/or mitigation. No further groundwater monitoring is recommended for the Property.

Soil Gas Impacts - Former Waste Oil Tank
PCE concentrations in exceedance of the ESL have been noted for a number of the soil gas sampling locations. Based on current data, an approximate PCE vapor plume delineation was developed, as depicted on Figure 4. The plume extends from the area of the former waste oil tank location toward the north. Based on the soil gas samples recovered along Cedar Boulevard (SG-14, SG-15), no significant soil gas concentrations exist to the south of the Property; therefore, the plume is limited to the subject Property.

A soil vapor extraction (SVE) system will likely be required across portions of the southerncentral area to mitigate the noted PCE impacts. A remedial action workplan (RAW) should be prepared to address SVE methodology and goals. A long-term vapor intrusion mitigation (VIMS) system will likely be required for structures overlying the vapor plume to address residual postremediation impacts.

Laboratory Qualifiers and Definitions
Method Detection Limit (MDL) - the minimum concentration of a substance that can be measured and reported with a 99% confidence that the analyte concentration is greater than zero
Matrix Spike (MS/MSD) - Client sample spiked with identical concentrations of target analyte (s). The spiking occurs prior to the sample preparation and analysis. They are used to document the precision and bias of a method in a given sample matrix.

Matrix - the component or substrate that contains the analyte of interest (e.g., - groundwater, sediment, soil, waste water, etc) Laboratory Control Sample (LCS ad LCSD) - A known matrix spiked with compounds representative of the target analyte(s). This is used to document laboratory performance.

Duplicate - a field sample and/or laboratory QC sample prepared in duplicate following all of the same processes and procedures used on the original sample (sample duplicate, LCSD, MSD)
Blank (Method/Preparation Blank) -MB/PB - An analyte-free matrix to which all reagents are added in the same volumes/proportions as used in sample processing. The method blank is used to document contamination resulting from the analytical process.

Practical Quantitation Limit/Reporting Limit/Limit of Quantitation (PQL/RL/LOQ) - a laboratory determined value at 2 to 5 times above the MDL that can be reproduced in a manner that results in a 99% confidence level that the result is both accurate and precise. PQLs/RLs/LODs reflect all preparation factors and/or dilution factors that have been applied to the sample during the preparation and/or analytical processes.

Precision (%RPD) - The agreement among a set of replicate/duplicate measurements without regard to known value of the replicates Surrogate (S) or (Surr) - An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical process, but which is not normally found in environmental samples. Surrogates are used in most organic analysis to demonstrate matrix compatibility with the chosen method of analysis
Tentatively Identified Compound (TIC) - A compound not contained within the analytical calibration standards but present in the GCMS library of defined compounds. When the library is searched for an unknown compound, it can frequently give a tentative identification to the compound based on retention time and primary and secondary ion match. TICs are reported as estimates and are candidates for further investigation.

Units: the unit of measure used to express the reported result - mg/L and mg/Kg (equivalent to PPM - parts per million in liquid and solid), ug/L and ug/Kg (equivalent to PPB - parts per billion in liquid and solid), ug/m3, mg/m3, ppbv and ppmv (all units of measure for reporting concentrations in air), % ( equivalent to 10000 ppm or 1,000,000 ppb), ug/Wipe ( concentration found on the surface of a single Wipe usually taken over a 100cm2 surface) B - Indicates when the analyte is found in the associated method or preparation blank D - Surrogate is not recoverable due to the necessary dilution of the sample E - Indicates the reportable value is outside of the calibration range of the instrument but within the linear range of the instrument (unless otherwise noted) Values reported with an E qualifier should be considered as estimated.

H- Indicates that the recommended holding time for the analyte or compound has been exceeded J- Indicates a value between the method MDL and PQL and that the reported concentration should be considered as estimated rather the quantitative NA - Not Analyzed
N/A - Not Applicable
ND - Not Detected at a concentration greater than the PQL/RL or, if reported to the MDL, at greater than the MDL.

NR - Not recoverable - a matrix spike concentration is not recoverable due to a concentration within the original sample that is greater than four times the spike concentration added
R- The % RPD between a duplicate set of samples is outside of the absolute values established by laboratory control charts S- Spike recovery is outside of established method and/or laboratory control limits. Further explanation of the use of this qualifier should be included within a case narrative
X -Used to indicate that a value based on pattern identification is within the pattern range but not typical of the pattern found in standards.

Further explanation may or may not be provided within the sample footnote and/or the case narrative.

DEFINITIONS:

Accuracy/Bias (% Recovery) - The closeness of agreement between an observed value and an accepted reference value.

Laboratory Qualifiers and Definitions
Method Detection Limit (MDL) - the minimum concentration of a substance that can be measured and reported with a 99% confidence that the analyte concentration is greater than zero
Matrix Spike (MS/MSD) - Client sample spiked with identical concentrations of target analyte (s). The spiking occurs prior to the sample preparation and analysis. They are used to document the precision and bias of a method in a given sample matrix.

Further explanation may or may not be provided within the sample footnote and/or the case narrative.

DEFINITIONS:

Accuracy/Bias (% Recovery) - The closeness of agreement between an observed value and an accepted reference value.

Laboratory Qualifiers and Definitions
Method Detection Limit (MDL) - the minimum concentration of a substance that can be measured and reported with a 99% confidence that the analyte concentration is greater than zero
Matrix Spike (MS/MSD) - Client sample spiked with identical concentrations of target analyte (s). The spiking occurs prior to the sample preparation and analysis. They are used to document the precision and bias of a method in a given sample matrix.

Further explanation may or may not be provided within the sample footnote and/or the case narrative.

DEFINITIONS:

Accuracy/Bias (% Recovery) - The closeness of agreement between an observed value and an accepted reference value.
