Prometheus Real Estate Group
1900 South Norfolk Street, Suite 150
San Mateo, California 94403
Subject: Phase II Environmental Site Investigation Report 415 and 445 South B Street, San Mateo, California 94401 Dear Mr. Kaz:
RMD Environmental Solutions, Inc., (RMD) has prepared a Phase II Environmental Site Investigation Report (Phase II Report) describing recent investigation activities for 415 and 445 South B Street in San Mateo, California (the Site; Figure 1). The RMD Proposal for Phase I and Phase II Environmental Site Assessment1 described a scope of work to assess whether contamination is present which may trigger an obligation to perform further investigation and/or mitigation measures or which otherwise could result in environmental liability should Prometheus Real Estate Group (Prometheus) purchase the Site for redevelopment. An additional Phase II investigation scope of work was proposed and implemented based on the findings of the initial Phase II investigation. The Site background, investigation objectives, scope of work, and results are provided in the Report sections below.
SITE BACKGROUND
The Site consists of two parcels totaling approximately 23,100 square feet north of East Fifth Avenue and east of South B Street and is identified as San Mateo County Assessor’s parcel numbers (APN) 034-179-030 and 034-179-040. The Site is currently developed with vacant retail units. Details regarding the Site operations, ownership, and improvements are included in the Phase I Environmental Site Assessment (ESA) report, prepared concurrently. The Site is shown on a Site Plan that is provided as Figure 2.
Prometheus intends to remove the existing building and construct commercial space over the entire building footprint. One design option includes an underground parking structure with a 1 RMD, 2020.

waterproofing membrane system. However, it has not yet been determined whether this design will ultimately be implemented.
SCOPE OF WORK
During the initial Phase II investigation in July 2020, the scope of work consisted of a combination of on-Site soil borings and soil vapor sampling, and-off Site grab groundwater collection, summarized as follows:
• Soil borings were advanced at three off-Site locations (SB-01, SB-02, and SB-03; Figure 2) for grab groundwater sample collection. Boring SB-03 produced insufficient water to collect a sample, a deep soil sample was collected instead. The soil borings were tremie grouted to the surface following the completion of sampling. On July 31, 2020, the boring locations were repaired at the surface with hot asphalt, pursuant to City of San Mateo encroachment permit requirements.
• Dual-nested soil vapor sample probes were installed at three on-Site locations (SVP-01, SVP-02, and SVP-03; Figure 2) at 3.5 feet below ground surface (bgs; SVP-02 and SVP03) or 4.5 feet bgs (SVP-01) and at 6.5 feet bgs (SVP-02 and SVP-03) or 7.5 feet bgs (SVP01) depth. The original target depth for the deeper probes was 9.5 feet bgs, however refusal was encountered at all on-Site borings before the target depth was reached, as further discussed in the sections that follow. Soil samples were collected at each location during installation. Each of the dual-nested soil vapor probes were sampled more than 48 hours after installation.
Based on findings of the initial Phase II investigation, an additional step-out investigation was conducted in September 2020. The additional investigation scope of work consisted of on-Site soil borings, grab groundwater sampling, and soil vapor sampling, summarized as follows:
• A soil boring was advanced at one location (SB-04; Figure 2) for grab groundwater sample collection. The soil boring was tremie grouted to the surface following the completion of sampling.
• Soil vapor sample probes were installed at four locations (SVP-04, SVP-05, SVP-06, and SVP-07; Figure 2) at 4.5 feet below ground surface (bgs) depth. The four probes were located approximately 30-40 feet away, roughly in each cardinal direction where access allowed, from previously installed probe SVP-02 in an attempt to delineate the lateral extent of tetrachloroethene (PCE) in soil vapor. Similar to the initial soil vapor probes, the step-out probes were planned to be installed as dual-nested probes, however refusal 10135 of 11211

was encountered at each of the borings before the target depth was reached and singlecompletion probes were installed instead. Soil samples were collected at each location during installation. Each of the soil vapor probes were sampled more than 48 hours after installation.
Drilling activities were conducted by Cascade Drilling (Cascade), a C-57 licensed contractor under the oversight of RMD personnel. All work was performed under direction of a California licensed geologist.
Further details are provided as follows.
PRE-FIELD ACTIVITIES
Prior to initiating field work, RMD performed the following pre-field activities:
• Marked the proposed sampling locations for Underground Service Alert (USA); • Prepared a Site-specific Health and Safety Plan;
• Obtained drilling permits from the San Mateo County Environmental Health Services Groundwater Protection Program (Attachment A);
• Obtained an encroachment permit from the City of San Mateo Public Works Department (Appendix A); and
• Conducted an underground utility survey to clear the proposed drilling locations of underground utilities and other possible subsurface obstructions.
SOIL LOGGING
During hand augering of each borehole, soil was visually characterized and described using the Unified Soil Classification System (USCS). Soil samples were field screened for total volatile organic compounds (VOCs) using a handheld photoionization detector (PID). At on-Site locations, shallow soil was comprised of well graded sand with gravel or sand with clay until approximately 7 to 8 feet bgs, when large rocks and bricks were encountered. The borings were terminated at these depths due to refusal with the hand auger. At off-Site locations, between approximately 1 foot bgs and 30 feet bgs, the soil was comprised of primarily clayey sand and sandy clay with intermittent relatively thin lenses of more permeable and gravelly soil.
Groundwater was encountered between approximately 28 and 31.5 feet bgs. No odors or elevated PID readings were observed during drilling activities. PID readings were either not detected or measured at very low concentrations that are not considered significant (the 10136 of 11211
Mr. Kaz
October 27, 2020
RMD ENVIRONMENTAL SOLUTIONS, INC.
maximum PID detection was 6.1 parts per million by volume [ppmv} measured in boring SVP-7).
The soil types and PID readings were recorded on boring logs (Attachment B).
SOIL SAMPLING
Soil samples were collected at each soil vapor probe boring location during hand augering and at boring SB-03 during direct-push drilling activities. At borings SVP-01, SVP-02, and SVP-03, soil samples were collected at approximately 1 foot within native soil, at approximately 5 feet bgs, and near the bottom of each boring. At borings SVP-04, SVP-05, SVP-06, and SVP-07, soil samples were collected at approximately 1 foot within native soil, at approximately 3 feet bgs, 5 feet bgs, and near the bottom of each boring. At boring SB-03, a soil sample was collected at 30 feet bgs in lieu of groundwater since the boring did not produce water sufficient for grab groundwater sample collection. At boring SB-04, soil samples were collected at approximately 5 feet bgs, 10 feet bgs, 15 feet bgs, and 20 feet bgs. Soil samples were collected in laboratorysupplied sample containers, labeled, placed in a chilled cooler, and transported under standard chain-of-custody (COC) protocol to Pace Analytical (Pace), a State-certified laboratory, for analysis. At each soil vapor probe location and boring SB-04, a composite of the discrete soil samples was analyzed for the following:
• Total petroleum hydrocarbons (TPH) as gasoline (TPHg), TPH as diesel (TPHd), and TPH as motor oil (TPHmo) using United States Environmental Protection Agency (USEPA) Method 8015;
• VOCs using USEPA Method 8260B; and
• California Administrative Manual (CAM)-17 Metals using USEPA Method 6020.
The discrete samples that made up the composite samples were placed on hold at the laboratory pending analysis of the composite samples. After reviewing the initial results of the composite samples, each of the discrete samples collected from soil vapor probe borings SVP-01 through SVP-05 were analyzed for lead using USEPA Method 6020.
The deep soil sample collected at boring SB-03 was analyzed for TPHg using USEPA Method 8015 and VOCs using USEPA Method 8260B.
GRAB GROUNDWATER SAMPLING
Four soil borings (SB-01 through SB-04) were advanced to approximately 32-34 feet bgs using a direct-push rig with a Macrocore sampler. Boring SB-03 was further advanced to approximately 40 feet bgs after no water initially entered the boring. Each boring was cleared to 5 feet bgs using a hand auger to confirm the absence of shallow obstructions. Once each boring reached 10137 of 11211
Mr. Kaz
October 27, 2020
RMD ENVIRONMENTAL SOLUTIONS, INC.
the target depth, temporary PVC casing with 10 feet of 0.010-inch machined-slot screen was installed to facilitate grab groundwater sample collection. Following sample collection, each boring was tremie-grouted with neat cement and capped with concrete to match surrounding grade.
Grab groundwater samples were collected at borings SB-01, SB-02, and SB-04 using a new disposable bailer and were transferred directly into laboratory-supplied sample containers.
Samples were labeled, placed in a chilled cooler, and transported under standard COC protocol to Pace for analysis. Grab groundwater samples were analyzed for TPHg and VOCs using USEPA Method 8260B. At boring SB-03, after a period of approximately 20 hours, there was insufficient groundwater to collect a sample.
SOIL VAPOR PROBE INSTALLATION
Seven soil borings (SVP-01 through SVP-07) were advanced to approximately 5-8 feet bgs using a hand auger. In borings SVP-01 through SVP-03 dual-nested soil vapor probes were installed in each boring. In borings SVP-04 through SVP-07 single completion soil vapor probes were installed in each boring. At each location an unknown obstruction, potentially a large rock, bricks, or buried concrete slab, was encountered above the target depth of 10 feet bgs and the borings were terminated. At boring SVP-01, soil vapor probes were installed at 4.5 feet bgs and
7.5 feet bgs. At borings SVP-02 and SVP-03, soil vapor probes were installed at 3.5 feet bgs and
6.5 feet bgs. At borings SVP-04 through SVP-07, soil vapor probes were installed at 4.5 feet bgs. Soil vapor probes were installed in accordance with the methods and procedures outlined in the Advisory – Active Soil Gas Investigations (Advisory)2. The soil vapor probes were constructed using 1/4-inch diameter Teflon™ tubing, fitted with a vapor probe implant installed at the target depth with a three-way valve at the surface. The annulus surrounding the implant was filled with #2/12 Monterey sand to six inches above and below the implant, followed by a one foot layer of dry granulated bentonite, and hydrated bentonite chips to the bottom of the shallow soil vapor probe for the deep probe or near ground surface for the shallow probe/single completion probe. A traffic-rated flush-mount vault box was installed at the surface of each location for protection. Soil vapor probe construction details were recorded in Table 1 and on the boring logs (Attachment B).

SOIL VAPOR PROBE SAMPLING
On July 29, 2020, the three dual-nested soil vapor probes (SVP-01, SVP-02, and SVP-03; six probes total) were sampled. On September 10, 2020, the four single completion soil vapor probes (SVP-04 through SVP-07) and the shallow probe at SVP-02 were sampled. Each soil vapor probe was sampled in accordance with the Advisory. At each probe a shut-in test was conducted and a total of three system volumes were removed prior to sampling. A helium shroud was used to conduct a leak test at each sampling point. An average of 21 to 36 percent (%) helium was monitored and maintained under the helium shroud during sample collection. Soil vapor samples were collected from each location in 1-liter SUMMATM canisters, labeled, handled under standard COC protocols, and transported to Pace for analysis. Replicate samples were collected from SVP-02 at 3.5 feet bgs during each sampling event. The samples were analyzed for TPHg and VOCs using USEPA Method TO-15, and fixed gases, helium and oxygen, using modified American Society for Testing and Materials (ASTM) Method D-1946.
INVESTIGATION RESULTS
SOIL
Soil analytical results were compared to the San Francisco Bay Regional Water Quality Control Board (SFBRWQCB) Tier 1 Environmental Screening Levels (ESLs)3 and Direct Exposure Human Health Risk Levels for Commercial/Industrial Shallow Soil Exposure (Commercial ESL). TPHg, TPHd, TPHmo, and VOC concentrations are presented on Table 2. None of the samples analyzed reported TPH or VOC detections above applicable screening levels. Metal concentrations are presented in Table 3. Metals with reported concentrations above Tier 1 ESLs, Commercial ESLs, and/or Bay Area Background Levels (Background Levels)4 are summarized as follows:
• Arsenic was detected above the Tier 1 ESL of 0.067 milligrams per kilogram (mg/kg) in each of the eight composite samples analyzed. However, all eight samples were below the Background Level of 11 mg/kg.
• Lead was detected above the Tier 1 ESL of 32 mg/kg and the Background Level of 24 mg/kg in five of the eight composite samples analyzed from borings SVP-01 through 3 San Francisco Bay Regional Water Quality Control Board. 2009. Tier 1 Environmental Screening Levels. 2019 Interim Final Rev. 2.

SVP-05. Based on these results, the 17 discrete soil samples from the five borings were analyzed for lead. Lead was detected above the Tier 1 ESL and the Background Level in eight of the 17 discrete samples analyzed. Lead concentrations ranged from 3.84 mg/kg in the sample collected from boring SVP-01 at 5 feet bgs to 607 mg/kg in boring SVP-05 at 3 feet bgs. Lead was detected above the Commercial ESL of 320 mg/kg in three discrete samples at concentrations of 444 mg/kg in boring SVP-02 at 1 foot bgs, 466 mg/kg in boring SVP-03 at 1 foot bgs, and 607 mg/kg in boring SVP-05 at 3 feet bgs. • Vanadium was detected above the Tier 1 ESL of 18 mg/kg in each of the eight composite samples analyzed. However, all eight samples were below the Background Level of 90 mg/kg. Vanadium was not detected above the Commercial ESL of 5,800 mg/kg in any of the analyzed samples.
• No additional metals were detected above the Tier 1 ESLs, Commercial ESLs, or Background Levels in the analyzed soil samples.
Based on the results, several samples were additionally analyzed using the waste extraction test (WET) for waste characterization. The soluble threshold limit concentration (STLC) extraction test and toxicity characteristic leaching procedure (TCLP) for lead and/or chromium was conducted on the samples, as identified on Table 3. All STLC and TCLP extraction results for chromium and lead in the composite samples were below the respective non-hazardous waste classification limits.
Laboratory analytical reports are included in Attachment C.
GROUNDWATER
Table 4 and Figure 3 summarize the grab groundwater analytical results. TPHg and VOC concentrations were compared to SFBRWQCB Tier 1 ESLs and Vapor Intrusion ESLs for Commercial/Industrial Land Use (Commercial VI ESL). A summary of the detections is as follows:
• TPHg was reported above the Tier 1 ESL of 100 micrograms per liter (µg/L) in two of three samples analyzed. TPHg concentrations were 122 µg/L at boring SB-01 and 180 µg/L at boring SB-02. Both samples were flagged as estimated values (J-flag) and the same analyte was found in the associated blank (B-flag). There is no established Commercial VI ESL for TPHg.
• Fuel-related VOCs including benzene, toluene, ethylbenzene, xylenes (BTEX), and methyl tert-butyl ether (MTBE) were not detected above RLs in two samples (SB-01 and SB-02) 10140 of 11211
Mr. Kaz
October 27, 2020
RMD ENVIRONMENTAL SOLUTIONS, INC.
and were detected near the RL at boring SB-04. The detections at SB-04 were J-flagged as estimated values and were below both the Tier 1 ESL and the Commercial VI ESL. • Tetrachloroethene (PCE) was detected above the Tier 1 ESL of 0.64 µg/L and the Commercial VI ESL of 2.8 µg/L in one of the three samples analyzed. PCE was detected in boring SB-04 at concentrations of 2.39 µg/L (primary sample) and 3.16 µg/L (duplicate sample).
• Trichloroethene (TCE) was detected above the RL in one of three samples analyzed, but was below the Tier 1 ESL of 1.2 µg/L and the Commercial VI ESL of 7.5 µg/L. TCE was detected in boring SB-04 at concentrations of 0.469 µg/L (primary sample; J-flag) and
0.696 µg/L (duplicate sample).
• cis-1,2-dichloroethene (DCE) was detected above the RL in one of three samples analyzed, but was below the Tier 1 ESL of 6.0 µg/L and the Commercial VI ESL of 210 µg/L. cis-1,2-DCE was detected in boring SB-04 at concentrations of 0.134 µg/L (primary sample) and 0.198 µg/L (duplicate sample). Both the primary and duplicate samples were J-flagged as estimated values.
• Vinyl chloride was not detected above RLs in the three samples collected. • Other VOCs, including chloroform and carbon disulfide, were reported at relatively low concentrations. These constituents either do not have an established ESL or are not considered chemicals of concern that would trigger additional investigation or mitigation.
The laboratory analytical report is included in Attachment C.
SOIL VAPOR
Tables 5, 6, and 7 and Figure 4 summarize the soil vapor analytical results. TPHg and VOC constituents were compared to SFBRWQCB Tier 1 ESLs and Subslab/Soil Gas Human Health Risk Screening Levels for Commercial Exposure (Commercial Soil Gas ESLs). All reported soil vapor concentrations were below the Tier 1 ESLs with the following exceptions:
• TPHg was detected above the Tier 1 ESL of 3,300 micrograms per cubic meter (µg/m3) in one of 11 samples and was not detected above the Commercial Soil Gas ESL of 83,000 µg/m3. TPHg was detected at a concentration of 6,900 µg/m3 at probe SVP-07. • Benzene was detected above the Tier 1 ESL of 3.2 µg/m3 in three of 11 samples and was detected above the Commercial Soil Gas ESL of 14 µg/m3 in one of 11 samples. Benzene was detected at concentrations of 10.6 µg/m3 at probe SVP-07, 10.9 µg/m3 at probe SVP05, and 24.2 µg/m3 at probe SVP-06. 10141 of 11211

• PCE was reported above the Tier 1 ESL of 15 µg/m3 in six of 11 samples and above the Commercial Soil Gas ESL of 67 µg/m3 in five of 11 samples. PCE concentrations ranged from 31.3 µg/m3 at probe SVP-02 at 6.5 feet bgs to 2,620 µg/m3 at probe SVP-05. • Methylene chloride was detected above the Tier 1 ESL of 34 µg/m3 in two samples. The maximum concentration was 139 µg/m3, which is below the Commercial Soil Gas ESL of 410 µg/m3. Methylene chloride is a common laboratory contaminant. • Other VOCs were detected above laboratory reporting limits, but were either below the Tier 1 ESL, Commercial Soil Gas ESL, and/or there is no established ESL and are not considered primary chemicals of concern.
Fixed gases including oxygen were analyzed at each soil vapor probe location. Oxygen concentrations ranged from 18.1% at probe SVP-02 at 6.5 feet bgs to 20.7% at probe SVP-07.
An oxygen concentration above 4% is an indication of a bioattenuation zone present in the subsurface5.
Laboratory analytical reports are included in Attachment C.
Quality Assurance/Quality Control Sampling
Helium was used as a leak check compound for collection of the soil vapor samples for analysis of TPHg and VOCs by USEPA Method TO-15. Helium was not detected above the laboratory reporting limit in the soil vapor samples collected, except for a detection of 0.136% in the sample collected at probe SVP-05. To evaluate the potential leak at probe SVP-05, a ratio of the concentration of helium measured in the sample to the average concentration of helium under the shroud during the sample collected was estimated. The helium leak ratio calculated for probe SVP-05 was 0.6%. A leak threshold of 5% is considered acceptable when a quantitative leak check compound is used under the sampling shroud (CalEPA, 2015). The estimated helium leak ratio is below the threshold; therefore, the TO-15 data were considered valid and representative. A summary of helium data is shown on Table 7.
A replicate sample was collected at probe SVP-02 at 3.5 feet bgs during each sampling event and analyzed for TPHg and VOCs using USEPA Method TO-15. The replicate samples were collected to evaluate data precision expressed in terms of percent difference. The relative percent difference (RPD) is calculated as follows:

RPD= ±(D1-D2)
(D1+D2)/2×100
During the July 29, 2020 sampling event, the RPD for soil vapor ranged from 0.3% (total xylenes) to 5.8% (benzene) with an average RPD of 2.5%, which is well below the 50% RPD target for soil vapor samples. During the September 10, 2020 sampling event, the RPD for soil vapor ranged from 10.4% (PCE) to 25.5% (toluene) with an average RPD of 18.6%, which is well below the 50% RPD target for soil vapor samples.
Laboratory analytical reports are included in Appendix C.
INVESTIGATION DERIVED WASTE MANAGEMENT
Investigation derived waste (IDW) consisted of soil cuttings. IDW was stored on-Site in properly labeled 55-gallon drums. Following waste characterization profiling, IDW will be disposed of in accordance with applicable laws and regulations.
DISCUSSION OF KEY RESULTS AND CONCLUSIONS
Soil samples collected from the Site indicate that lead is present in soil at concentrations that would require management and/or mitigation during site redevelopment. Mitigation measures could consist of offsite disposal or consolidation and capping under future buildings or hardscape areas. Administrative controls, including a deed restriction and/or Site Management Plan, would be required if and to the extent that the lead-impacted soil is not removed from the property. STLC and TCLP soil analytical results demonstrate the chromium and lead detected in the composite samples does not fall under hazardous waste classification.
TPHg was detected above the Tier 1 ESL for groundwater at off-Site borings SB-01 and SB-02 however was not detected above the reporting limit (RL) at on-Site boring SB-04. Petroleumrelated chemicals, including TPHg and benzene were reported in soil vapor beneath the property. Based on the distribution of petroleum constituents, the presence of upgradient and cross-gradient historic service stations (Figure 5), and the expected groundwater flow direction, petroleum impacts are likely attributed to an off-Site source. RMD notes that oxygen concentrations reported in each of the soil vapor samples indicated a bioattenuation zone is present in the subsurface.
PCE was detected above the Tier 1 ESL for groundwater in the sample collected on the downgradient property line (SB-04) at a concentration of 3.16 µg/L. This concentration above the commerical vapor intrusion ESL of 2.8 µg/L. PCE was detected above the Tier 1 ESL and the Commercial Soil Gas at soil vapor probes SVP-02, SVP-04, SVP-05, and SVP-06; 10143 of 11211

concentrations decreased with depth at the SVP-02 location. Although there is no documented use of chlorinated solvents at the Subject Site, the distribution of PCE in the subsurface suggests the possibility of an on-Site PCE source. An indoor air assessment should be conducted in the current building, if occupied, to evaluate potential vapor intrusion risk.
In summary, petroleum constituents have migrated onto the property from upgradient source(s) and PCE is present beneath the property at concentrations above regulatory screening levels for mitigation. In addition, lead is present in shallow soil at concentrations above applicable screening levels. Should Prometheus purchase the property, regulatory oversight and mitigation and/or administrative controls will be required during property redevelopment related to 1) shallow soil impacted with lead and 2) soil and groundwater management related to petroleum and chlorinated solvent impacts to soil vapor and groundwater. If the development plan remains to excavate for subterranean parking, then such excavation activities should resolve the presence of lead in soil and any source of PCE in shallow soil (if present). A vapor barrier may be required beneath future building footprints unless post-excavation sampling confirm that volatile organic compounds are no longer present at concentrations that pose a vapor intrusion risk. RMD notes that additional investigation may be required by the regulatory agencies to further delineate PCE in soil vapor offsite and/or post-excavation.

SUBSURFACE DRILLING PERMIT APPLICATION
REQUIREMENTS:
An accurate and correct map must be submitted with the application and include the following: north arrow, existing and historic site features, existing and proposed well/boring locations with ID's to scale, property lines and any other pertinent information. A work plan describing the drilling and construction/destruction methodology must be submitted to County staff.
A complete application with appropriate fees must be submitted 3 working days in advance of drilling and notification of start date and time must be provided at least 2 working days prior to drilling. The permit is subject to both General and Special Conditions stated below. A copy of the approved Subsurface Drilling Permit must be available on site while work related to the permit is being performed. Drilling may begin at the notified date and time whether County staff is present or not.
GENERAL CONDITIONS:
A. Field notification must be provided to GPP drilling inspection staff at least 2 full working days prior to the start of drilling.
GPP Caseworker also must be notified if site is associated with a remedial action case.
B. Well and boring construction and destruction under this permit are subject to the Standards for the Construction of Wells in San Mateo County, County Groundwater Protection Program (GPP) Guidelines, Policies & Procedures, the State Water Well Standards, and any instructions by a Health Department representative.
C. Well/Boring Owner, Driller, and Responsible Professional assume responsibility for all activities and uses under the permit, including compliance with Workmen's Compensation Laws, and indemnify, defend and save the County of San Mateo, its officers, agents and employees, free and harmless from any and all expense, cost, or liability in connection with or resulting from work or stopped-work associated with the permit, including, but not limited to, property damage, personal injury, wrongful death, and loss of income.
D. All borings must be properly destroyed (grouted/sealed) within 24 hours of drilling, unless special conditions are approved beforehand in writing as part of this permit, and must be continuously protected and stabilized.
E. Analytical results of all soil, vapor, and groundwater samples collected during the execution of drilling under this permit must be submitted to County GPP staff by the Responsible Professional within 60 days of sample collection. If contamination is discovered during drilling, verbal notification to County GPP by the Responsible Professional is required within 72 hours of discovery. Proper storage, labeling & disposal of investigation-derived residual wastes are the responsibility of the consultant unless stated otherwise contractually.
F. Boring logs, well construction details, and finalized as-built location map for all borings/ wells (except geotechnical borings) signed by a Responsible Professional, must be submitted to County GPP by the Responsible Professional within 60 days of drilling/construction/destruction. DWR Form 188 must be filed with the State per water code 13752.
G. Permit is valid only for the purpose specified herein. No change in purpose or required procedures, as described on this permit application, in the associated workplan, or in the special conditions below, will be allowed except upon written permission from the County. Construction aspects can be changed based on conditions encountered in the field.
H. Permit is valid for one mobilization associated with originally permitted boring/well locations only, including contingency locations, and is automatically canceled if not exercised, or if an extension is not applied for and granted within 120 days of the original permit issuance date.

Subject: Letter of Intent for Encroachment Permit
415 and 445 South B Street
San Mateo, California
Ms. Magallanes:
RMD Environmental Solutions, Inc. (RMD) is conducting a due diligence investigation for the property located at 415 and 445 South B Street in San Mateo, California (Subject Property) to evaluate subsurface conditions which may trigger mitigation measures or possible environmental liability should our client purchase the property.
SCOPE OF WORK
RMD is planning to advance three soil borings in the City of San Mateo right-of-way for collection of grab groundwater samples as part of a due diligence investigation for our client. The three soil borings will be installed at the approximate locations shown on the attached figure. The borings will be advanced using a direct-push drill rig to the target depth of 30 feet below ground surface. A grab groundwater sample will be collected from each soil boring and the borings will be backfilled with neat cement grout and capped with concrete to match the surrounding grade. The drilling activities will be conducted by a California-licensed driller with the oversight of RMD.
KEY ASSUMPTIONS
Hot asphalt patching in the city right-of-way is not required for boring locations.
PROPOSED SCHEDULE
The proposed drilling is tentatively scheduled for July 27, 2020 pending approval of this encroachment permit application.
Sincerely,
RMD ENVIRONMENTAL SOLUTIONS, INC.

A work plan describing the drilling and construction/destruction methodology must be submitted to County staff.
A complete application with appropriate fees must be submitted 3 working days in advance of drilling and notification of start date and time must be provided at least 2 working days prior to drilling. The permit is subject to both General and Special Conditions stated below. A copy of the approved Subsurface Drilling Permit must be available on site while work related to the permit is being performed. Drilling may begin at the notified date and time whether County staff is present or not.
GENERAL CONDITIONS:
A. Field notification must be provided to GPP drilling inspection staff at least 2 full working days prior to the start of drilling.
GPP Caseworker also must be notified if site is associated with a remedial action case.
B. Well and boring construction and destruction under this permit are subject to the Standards for the Construction of Wells in San Mateo County, County Groundwater Protection Program (GPP) Guidelines, Policies & Procedures, the State Water Well Standards, and any instructions by a Health Department representative.
C. Well/Boring Owner, Driller, and Responsible Professional assume responsibility for all activities and uses under the permit, including compliance with Workmen's Compensation Laws, and indemnify, defend and save the County of San Mateo, its officers, agents and employees, free and harmless from any and all expense, cost, or liability in connection with or resulting from work or stopped-work associated with the permit, including, but not limited to, property damage, personal injury, wrongful death, and loss of income.
D. All borings must be properly destroyed (grouted/sealed) within 24 hours of drilling, unless special conditions are approved beforehand in writing as part of this permit, and must be continuously protected and stabilized.
E. Analytical results of all soil, vapor, and groundwater samples collected during the execution of drilling under this permit must be submitted to County GPP staff by the Responsible Professional within 60 days of sample collection. If contamination is discovered during drilling, verbal notification to County GPP by the Responsible Professional is required within 72 hours of discovery. Proper storage, labeling & disposal of investigation-derived residual wastes are the responsibility of the consultant unless stated otherwise contractually.
F. Boring logs, well construction details, and finalized as-built location map for all borings/ wells (except geotechnical borings) signed by a Responsible Professional, must be submitted to County GPP by the Responsible Professional within 60 days of drilling/construction/destruction.

Construction aspects can be changed based on conditions encountered in the field.
H. Permit is valid for one mobilization associated with originally permitted boring/well locations only, including contingency locations, and is automatically canceled if not exercised, or if an extension is not applied for and granted within 120 days of the original permit issuance date. Failure to notify staff of cancellation or delay in start time will result in the Consultant being billed an Inspection Cancellation fee if GPP staff attempted to perform an inspection. Fees are listed at smchealth,org/ehfees
I. Wells installed under this permit may not be used for domestic, municipal, agricultural, or irrigation water supply.
J. All work performed must conform to Business and Profession Codes and State Water Well Standards.

L. Latitude and longitude of all wells must be surveyed with sub-meter accuracy relative to NAD83 and submitted to County GPP within 60 days of drilling, and to State Geo Tracker as appropriate.
M. Violation of any requirement or general or special permit condition may result in an order by GPP staff to cease work under this permit, correct the violation, potentially re-permit the work as a new mobilization, and potential actions may be taken against the Well Owner, Property Owner, or Responsible Professional by GPP.

Subject: Letter of Intent for Encroachment Permit
415 and 445 South B Street
San Mateo, California
Ms. Magallanes:
RMD Environmental Solutions, Inc. (RMD) is conducting a due diligence investigation for the property located at 415 and 445 South B Street in San Mateo, California (Subject Property) to evaluate subsurface conditions which may trigger mitigation measures or possible environmental liability should our client purchase the property.
SCOPE OF WORK
RMD is planning to advance three soil borings in the City of San Mateo right-of-way for collection of grab groundwater samples as part of a due diligence investigation for our client. The three soil borings will be installed at the approximate locations shown on the attached figure. The borings will be advanced using a direct-push drill rig to the target depth of 30 feet below ground surface. A grab groundwater sample will be collected from each soil boring and the borings will be backfilled with neat cement grout and capped with concrete to match the surrounding grade. The drilling activities will be conducted by a California-licensed driller with the oversight of RMD.
KEY ASSUMPTIONS
Hot asphalt patching in the city right-of-way is not required for boring locations.
PROPOSED SCHEDULE
The proposed drilling is tentatively scheduled for July 27, 2020 pending approval of this encroachment permit application.
Sincerely,
RMD ENVIRONMENTAL SOLUTIONS, INC.

CASE NARRATIVE ONE LAB. NATIONWIDE.
All sample aliquots were received at the correct temperature, in the proper containers, with the appropriate preservatives, and within method specified holding times, unless qualified or notated within the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control are within established criteria except where addressed in this case narrative, a non-conformance form or properly qualified within the sample results. By my digital signature below, I affirm to the best of my knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the quality of the data have been identified by the laboratory, and no information or data have been knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS ONE LAB. NATIONWIDE.
Guide to Reading and Understanding Your Laboratory Report The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
(dry) Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils].
MDL Method Detection Limit.
MDL (dry) Method Detection Limit.
RDL Reported Detection Limit.
RDL (dry) Reported Detection Limit.
Rec. Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte.
Uncertainty
(Radiochemistry) Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss) This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis.
Qualifier Description
B The same analyte is found in the associated blank.
J The identification of the analyte is acceptable; the reported value is an estimate.
J3 The associated batch QC was outside the established quality control range for precision.
J4 The associated batch QC was outside the established quality control range for accuracy.
J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high.
J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low.
V The sample concentration is too high to evaluate accurate spike recoveries. 1 Cp

CASE NARRATIVE ONE LAB. NATIONWIDE.
All sample aliquots were received at the correct temperature, in the proper containers, with the appropriate preservatives, and within method specified holding times, unless qualified or notated within the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control are within established criteria except where addressed in this case narrative, a non-conformance form or properly qualified within the sample results. By my digital signature below, I affirm to the best of my knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the quality of the data have been identified by the laboratory, and no information or data have been knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS ONE LAB. NATIONWIDE.
Guide to Reading and Understanding Your Laboratory Report The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
(dry) Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils].
MDL Method Detection Limit.
MDL (dry) Method Detection Limit.
RDL Reported Detection Limit.
RDL (dry) Reported Detection Limit.
Rec. Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte.
Uncertainty
(Radiochemistry) Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss) This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis.
Qualifier Description
B The same analyte is found in the associated blank.
E
The analyte concentration exceeds the upper limit of the calibration range of the instrument established by the initial calibration (ICAL).
J The identification of the analyte is acceptable; the reported value is an estimate.
J1 Surrogate recovery limits have been exceeded; values are outside upper control limits.
J4 The associated batch QC was outside the established quality control range for accuracy.
J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high.
J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low.
V The sample concentration is too high to evaluate accurate spike recoveries. 1 Cp

CASE NARRATIVE ONE LAB. NATIONWIDE.
All sample aliquots were received at the correct temperature, in the proper containers, with the appropriate preservatives, and within method specified holding times, unless qualified or notated within the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control are within established criteria except where addressed in this case narrative, a non-conformance form or properly qualified within the sample results. By my digital signature below, I affirm to the best of my knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the quality of the data have been identified by the laboratory, and no information or data have been knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS ONE LAB. NATIONWIDE.
Guide to Reading and Understanding Your Laboratory Report The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL Reported Detection Limit.
Rec. Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte.
Uncertainty
(Radiochemistry) Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss) This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis.
Qualifier Description
B The same analyte is found in the associated blank.
J The identification of the analyte is acceptable; the reported value is an estimate.
J4 The associated batch QC was outside the established quality control range for accuracy. 1 Cp

CASE NARRATIVE ONE LAB. NATIONWIDE.
All sample aliquots were received at the correct temperature, in the proper containers, with the appropriate preservatives, and within method specified holding times, unless qualified or notated within the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control are within established criteria except where addressed in this case narrative, a non-conformance form or properly qualified within the sample results. By my digital signature below, I affirm to the best of my knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the quality of the data have been identified by the laboratory, and no information or data have been knowingly withheld that would affect the quality of the data.

Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
(dry) Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils].
MDL Method Detection Limit.
MDL (dry) Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL Reported Detection Limit.
RDL (dry) Reported Detection Limit.
Rec. Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte.
Uncertainty
(Radiochemistry) Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss) This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis.

CASE NARRATIVE ONE LAB. NATIONWIDE.
All sample aliquots were received at the correct temperature, in the proper containers, with the appropriate preservatives, and within method specified holding times, unless qualified or notated within the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control are within established criteria except where addressed in this case narrative, a non-conformance form or properly qualified within the sample results. By my digital signature below, I affirm to the best of my knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the quality of the data have been identified by the laboratory, and no information or data have been knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS ONE LAB. NATIONWIDE.
Guide to Reading and Understanding Your Laboratory Report The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
(dry) Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils].
MDL Method Detection Limit.
MDL (dry) Method Detection Limit.
RDL Reported Detection Limit.
RDL (dry) Reported Detection Limit.
Rec. Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte.
Uncertainty
(Radiochemistry) Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss) This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis.
Qualifier Description
J The identification of the analyte is acceptable; the reported value is an estimate.
J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high.
J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low. 1 Cp

CASE NARRATIVE ONE LAB. NATIONWIDE.
All sample aliquots were received at the correct temperature, in the proper containers, with the appropriate preservatives, and within method specified holding times, unless qualified or notated within the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control are within established criteria except where addressed in this case narrative, a non-conformance form or properly qualified within the sample results. By my digital signature below, I affirm to the best of my knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the quality of the data have been identified by the laboratory, and no information or data have been knowingly withheld that would affect the quality of the data.
