UPDATED PHASE II ENVIRONMENTAL SITE ASSESSMENT
Reference: ENGEO, Phase I Environmental Site Assessment, 282 South Montgomery Street, San Jose, California; Project No. 14121.001.000; DRAFT, February 28, 2018.
Dear Mr. Jodry: We are pleased to submit the findings of our phase II environmental site assessment (ESA) undertaken at the subject property (Property) in San Jose, California. The purpose of this phase II ESA is to address potential subsurface impairments associated with the past uses of the Property, and the potential migration of offsite impact from neighboring sites. BACKGROUND
The Property is located at 282 South Montgomery Street in San Jose, California (Figure 1). The approximately 0.5-acre Property is identified with Assessor's Parcel Number (APN) 259-47-080. Former addresses associated with the Property include 649 West San Carlos Street and 589 Lorraine Avenue. The Property is located northeast to the intersection of South Montgomery Street and West San Carlos Street, and is comprised of a large footprint building occupied by a car rental facility and a packaging business. ENGEO conducted a phase I ESA for the Property (Reference). Based on the findings of the referenced Phase I ESA, the following Recognized Environmental Condition (REC) was noted:
A review of historical records found that the Property had been used a gasoline service station and a dry cleaning facility in the past. There could be potential surface and subsurface impacts to the Property due to its past uses. Additionally, there could be a potential vapor intrusion risk.
No historical RECs and no controlled RECs were identified for the Property; however, the following potential environmental concerns were identified for the Property:
Given the age of the existing structure, it is conceivable that asbestos-containing materials and lead-based paint materials may exist within the structure.
Based on both the review of regulatory databases and the areas historic industrial land uses, potential sources of offsite groundwater impact exist within the vicinity of the Property.

UPDATED PHASE II ENVIRONMENTAL SITE ASSESSMENT Page 2
A phase II environmental site assessment was proposed for the Property, including the recovery of soil, groundwater, and soil gas samples, to address potential subsurface impairments associated with the past uses of the Property, and the potential migration of offsite impact from neighboring sites. Further, given the past use of the Property as a dry cleaning facility and a gasoline service, ENGEO recommended the preparation of a Site Management Plan (SMP) to outline procedures and protocols to handle impacted materials. SCOPE OF FIELD EXPLORATION
Initial field sampling activities associated with the phase II ESA were performed on February 28, 2018, and a second round of sampling was conducted on March 28 and 29, 2018. Prior to drilling, an ENGEO representative contacted USA North Service Alert for identification of underground utilities at the Property. Subsequently, as a precautionary measure, a private utility locator was retained to clear the sample locations. A C-57 licensed drilling contractor was retained to advance borings using a Geoprobe® direct-push rig. During the first round of sampling, soil samples were collected from five locations (S-1 through S-5), groundwater samples were collected from three of the five locations (GW-2, GW-4, and GW-5), and soil gas samples were collected from five locations (SG-1 through SG-5), as presented on Figure 2. The drilling contractor cored through the concrete slab and pushed through to collect samples at the interior locations (S-3 and SG-3). The second round of sampling included the collection of soil samples from an additional 11 locations (S-6 through S-16), groundwater samples from an additional four locations (GW-6, GW-7, GW-8, and GW-16), and collection of soil gas samples from an additional seven locations (SG-6 through SG-12). Indoor air and ambient air samples were also collected during the second round of sampling. In addition, a groundwater and a soil gas sample was collected from the adjacent Car Wash parcel across the road on South Montgomery Street (655 West San Carlos Street), Details pertaining to each of these tasks are presented below. Task 1: Soil Assessment
A soil sampling study was performed to address potential subsurface impairments associated with the past use of Property. A total of 16 soil borings (S-1 through S-16) were advanced at the Property to a total depth of 10 feet below ground surface (Figure 2). Soil samples were retrieved within continuous acetate core liners measuring 5 feet in length. During drilling, a photoionization detector (PID) was used to screen the soil cores. Soil samples were generally retrieved from depths of 1 foot, 5 feet, and 10 feet below ground surface. Following recovery, the soil samples were sealed using Teflon® sheets secured by tight-fitting plastic end caps and tape. Upon collection, a label was placed on the sample that included a unique sample number, sample location, time/date collected, laboratory analysis, and the sampler’s identification. The soil samples were placed in an ice-cooled chest and submitted under documented chain-of-custody to Torrent Laboratory, Inc., a State-certified laboratory in Milpitas, California.

UPDATED PHASE II ENVIRONMENTAL SITE ASSESSMENT Page 3
The soil samples collected during the first round of sampling were analyzed for the presence of CAM-17 metals (EPA Method 6010/7471), volatile organic compounds (VOCs) and total petroleum hydrocarbons as gasoline (TPH-g) (EPA Method 8260), and TPH-diesel (TPH-d) and TPH-motor oil (TPH-mo) (EPA Method 8015M with silica gel cleanup). Additionally, soil samples recovered from the 1-foot depth interval were analyzed for semi-volatile organic compounds (SVOCs) (EPA Method 8270C SIM). The soil samples collected during the second round of sampling were analyzed for VOCs (EPA Method 8260). The boreholes were filled with neat cement grout upon completion of sampling. Task 2: Grab Groundwater Assessment
Grab groundwater samples were recovered from seven of the 16 sample locations on the Property (GW-2, GW-4, GW-5, GW-6, GW-7, GW-8, and GW-16) and from one location on the adjacent Car Wash parcel (CW-GW) as shown on Figure 2. The soil borings were advanced deeper until groundwater was first encountered. Groundwater was encountered at a depth of approximately 20 to 25 feet below the ground surface. Temporary PVC casings were used in each borehole to facilitate collection. Upon collection, groundwater samples were placed into laboratory-provided sample containers. Each container was labeled with a sample identification, sample location, date and time of collection, and sampler’s identification. The groundwater samples were then placed in an ice-cooled chest and submitted under documented chain-of-custody to Torrent Laboratory, Inc. A representative groundwater sample for laboratory analysis could not be collected from location GW-4 since there was not enough groundwater encountered in this boring which was advanced to approximately 30 feet below ground surface. Grab groundwater samples GW-2 and GW-5 were analyzed for the presence of TPH-g and VOCs (EPA Method 8260), and TPH-d and TPH-mo (EPA Method 8015M with silica gel cleanup), and CAM-17 metals (EPA Method 6010/7471). All other grab groundwater samples were analyzed for VOCs (EPA Method 8260). Following sample recovery, the temporary well points were removed and backfilled with neat cement grout. Task 3: Soil Gas Assessment In order to evaluate potential vapor intrusion issues at the Property, given the past uses of the Property as a gasoline service station and a dry cleaning facility, soil gas samples were collected from a total of 12 locations (SG-1 through SG-12) across the Property, and from one location on the adjacent Car Wash parcel (CW-SG) (Figure 2). The installation and sampling of the soil gas borings were performed in general conformance with the Department of Toxic Substances Control (DTSC) Final Advisory Active Soil Gas Investigations (July 2015), using the following procedures:
The temporary soil vapor monitoring well casings were constructed with ¼-inch-diameter Teflon® tubing equipped with a 6-inch stainless steel filter at the base of the tubing. The temporary well installation was performed with a Geoprobe® direct-push rig, which advanced an approximately 2-inch-diameter boring to a depth of 6 feet below the ground surface.

UPDATED PHASE II ENVIRONMENTAL SITE ASSESSMENT Page 4
The bottom of the well casing was equipped with a 6-inch-long filter centered in the middle of a 2-foot layer of No. 3 sand. Six inches of dry bentonite was installed on top of the sand, and the remaining annular space was filled with hydrated bentonite grout to the surface.
For the soil gas well installed at SG-3 (inside the building), the total depth was 10 feet below ground surface, and the filter was installed at a depth of 9 feet below ground surface.
Following installation of the annular seal, the well casings were sealed, and the mandatory 2-hour equilibration time began. 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 100 to 200 milliliters per minute (ml/min).
Following the mandatory equilibration time, a purge canister was attached to the manifold connection closest to the well casing and the sample canister was connected to the manifold fitting furthest away from the well casing. 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 is a drop in vacuum.
A minimum of three well volumes were purged from the wells. Once purging was complete, the valve on the purge canister was closed. Samples were collected by opening the sample canister valve and allowing the sample canister to extract soil vapor until the vacuum in the sample canister reached approximately 5 inches of mercury. The leak detection compound 1,1-diflouroethane (1,1-DFA) was applied by wrapping a doused rag around the manifold fittings during sample collection.
Each sample canister was labeled with a unique identification number, sampling time, and pre- and post-sample vacuum readings. All soil gas samples were collected and submitted to a State-certified laboratory under documented chain-of-custody for analysis of TPH-gasoline and volatile organic compounds (VOCs), by EPA Test Method TO-15.
Task 4: Indoor Air and Ambient Air Sampling In order to address potential human health risks within the building at the Property, indoor air sampling was conducted. Indoor air sampling was performed at four locations (IA-1 through IA-4) inside the building, in accordance with the Final Guidance for the Evaluation and Mitigation of Subsurface Vapor Intrusion to Indoor Air, Department of Toxic Substances Control, October 2011. In addition, two ambient air samples (AA-1 and AA-2) were collected from the Property at the same time. The scope of services included the following:
Four 6-liter summa canisters were deployed inside the building, as presented on Figure 2. Summa canisters were deployed in the breathing space 3 to 5 feet above ground and were equipped with an 8-hour flow controller. The sampling was conducted for an 8-hour duration during business hours to mimic a typical working day.
For the ambient air samples, two 6-liter summa canisters were deployed at the Property (Figure 2). The summa canisters were equipped with an 8-hour flow controller.
The four indoor air samples and two ambient air samples were submitted to a State-certified laboratory for analysis of VOCs by EPA Test Method TO-15, SIM mode.

ANALYTICAL RESULTS Soil As presented in Table A, detected analytes in soil were compared to their respective San Francisco Regional Water Quality Control Board’s (SFRWQCB) Environmental Screening Levels (ESLs) for direct exposure to shallow soil for both residential and commercial land use1,2. Review of the laboratory test results found detectable concentrations of several metallic analytes, including arsenic, barium, chromium, cobalt, copper, lead, nickel, selenium, vanadium, and zinc in the soil samples collected from the Property. Select soil samples exhibited arsenic concentrations in excess of their respective screening levels for both residential and commercial land use. However, the reported arsenic concentrations, ranging between non-detect mg/kg and 9.07 milligrams per kilograms (mg/kg), are consistent with expected background soil concentrations in the San Francisco Bay Area. Soil sample S-5@1’ exhibited a concentration of lead (358 mg/kg) in excess of both, its corresponding residential ESL of 80 mg/kg and the corresponding commercial ESL of 320 mg/kg. Because the soil sample exhibited a lead concentration in excess of 50 mg/kg, which is greater than 10 times the respective soluble threshold limit concentration (STLC) of 5 milligrams per liter (mg/L), if removal and off-site transport of soil from this location is contemplated, it is recommended that subsequent analysis be performed using the Waste Extraction Test (WET) to determine the soluble concentration. All other concentrations of metals were below the corresponding ESLs or within background concentrations. TPH-d and TPH-mo were detected in the soil samples collected from the Property; however, the detected concentrations are below the corresponding ESLs. TPH-g, toluene, and tetrachloroethene (PCE) were the only VOCs detected in soil at the Property. TPH-g and toluene were detected at concentrations below the corresponding ESLs. PCE concentrations in two soil samples (S10@1’ and S16@10’) exceeded the corresponding residential ESL of 600 micrograms per kilogram (µg/kg) as well as the corresponding commercial/industrial ESL of 2,700 µg/kg. As presented in Table A, PCE concentrations in eight samples exceeded the corresponding residential ESL, but were below the corresponding commercial/industrial ESL. PCE concentrations in soil are presented on Figure 3. Pyrene and benzo(b)fluoranthene were the only SVOCs detected in one soil samples collected at a depth of 1 foot below ground surface (S-2@1’). These concentrations are below the corresponding residential and commercial/industrial ESLs. A summary of the soil sample analytical results is presented in Table A. The laboratory results are presented in their entirety in Appendix A.

Groundwater
Review of the laboratory test results found detectable concentrations of several metallic analytes, including barium, nickel, and selenium in the grab groundwater samples collected from the Property. The detectable concentrations of metals are reported below the corresponding groundwater ESLs.3 As presented in Table B, TPH-d and TPH-mo were not detected in the groundwater samples. TPH-g was detected at concentrations of 1,120 and 209 micrograms per liter (µg/L) in groundwater samples GW-2 and GW-5, respectively. The TPH-g concentration at GW-2 exceeds the corresponding groundwater ESL. VOCs, including 1,2-dichlorothane, 1,1-dichloropropene, PCE, trichloroethene (TCE), cis-1,2-dichloroethene (cis-1,2-DCE), trans-1,2-dichloroethene (trans-1,2-DCE), and toluene were detected in the grab groundwater samples collected from the Property. TCE, 1,2-dichloroethane, cis-1,2-DCE, and PCE concentrations exceed the corresponding ESLs in the grab groundwater samples collected from the Property. PCE was not detected in the grab groundwater sample collected at the adjacent Car Wash parcel. PCE concentrations in groundwater are presented on Figure 4. A summary of the groundwater analytical results is presented in Table B. The laboratory results are presented in their entirety in Appendix A. Soil Gas VOCs, including 1,2,4-trimethylbenzene, 2-butanone, benzene, acetone, tert-butanol, 2-hexanone, 1,1,2-dichloroethane, 4-ethyltoluene, 4-methyl-2-pentanone, carbon disulfide, ethylbenzene, hexane, xylenes, PCE, naphthalene, toluene, and TPH-g were detected in the soil gas samples collected from the Property. Results were compared to the corresponding SFRWQCB’s ESLs for vapor intrusion for both residential and commercial land use45. With the exception of PCE, concentrations of the VOCs are below the corresponding ESLs. Reported concentrations of PCE ranged between 620 to 150,000 micrograms per cubic meter (µg/m3) in the samples collected from the Property. PCE concentrations at the Property exceed both the corresponding residential and commercial ESLs for vapor intrusion. PCE was detected at a concentration of 200 µg/m3 in the soil gas sample (CW-SG) collected from the adjacent Car Wash parcel, which is below both the corresponding residential and commercial ESLs for vapor intrusion. PCE concentrations in soil gas are presented on Figure 5. A summary of the soil gas analytical results is presented in Table C. The laboratory results are presented in their entirety in Appendix A.

Indoor Air and Ambient Air Several VOCs were detected in the indoor air and ambient air samples collected from the Property (Appendix A). A summary of results for PCE and its breakdown products is presented in Table D. Indoor air and ambient air results were compared to the RWQCB ESLs, as well as the United States Environmental Protection Agency’s (USEPA) Regional Screening Levels (RSLs). PCE concentrations in all four indoor air sample exceeded the corresponding residential and commercial ESLs, however, concentrations in all samples were below the commercial RSLs. PCE concentrations in two samples (IA-1 and IA-2) exceeded the residential RSL, but were below the commercial RSLs. In the two ambient air samples collected from the Property, PCE was detected at concentrations exceeding the corresponding residential ESL, but was below the commercial ESL, as well as the residential and commercial RSLs. The concentration of vinyl chloride exceeded the residential ESL in one sample (IA-4), but was below the corresponding commercial ESL and RSL. The laboratory results are presented in their entirety in Appendix A. DISCUSSION AND CONCLUSION Review of the laboratory test results found areas of isolated soil impact with select target analytes exceeding the corresponding residential screening levels and/or commercial/industrial screening levels. The groundwater samples recovered from the Property exhibited concentrations in excess of the respective ESLs in one or more of the following VOCs: 1,2-dichlorothane, PCE, TCE, and
cis-1,2-DCE. Sample GW-2 also exhibited an elevated concentration of TPH-g (1,120 g/L). Elevated concentrations of PCE were observed in the soil gas samples collected from across the Property. These concentrations exceed both the residential and commercial/industrial ESLs for vapor intrusion. Elevated concentrations of PCE were also observed in the indoor air samples collected from the Property, indicating that indoor air concentrations exceed respective screening levels inside the building as described in preceding sections. Concentrations of PCE in the soil gas and groundwater samples collected from the adjacent Car Wash parcel were below respective screening levels, indicating that this parcel does not appear to have been environmentally impacted. The elevated concentrations of PCE in soil, groundwater, and soil gas on the Property indicates that a release associated with the former dry cleaner has occurred on the Property, and remediation would be required to reduce the concentrations of PCE in soil gas and groundwater prior to redevelopment. In addition, there could be a potential offsite source contributing. Sampling activities were recently conducted at the adjacent parcel to the east (580 Lorraine Avenue). Offsite impacts will be evaluated based on the results of sampling conducted at that site. In order to avoid delays associated with the proposed development, we would recommend reaching out to appropriate Regulatory Agencies to enter into a Voluntary Oversight Agreement for remediation and/or mitigation activities.

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 factorsand/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, butwhich is not normally found in environmental samples. Surrogates are used in most organic analysis to demonstrate matrix compatibility with the chosen methodof 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 timeand 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.
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 factorsand/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, butwhich is not normally found in environmental samples. Surrogates are used in most organic analysis to demonstrate matrix compatibility with the chosen methodof 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 timeand 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.
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 factorsand/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, butwhich is not normally found in environmental samples. Surrogates are used in most organic analysis to demonstrate matrix compatibility with the chosen methodof 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 timeand 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.
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 factorsand/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, butwhich is not normally found in environmental samples. Surrogates are used in most organic analysis to demonstrate matrix compatibility with the chosen methodof 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 timeand 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.
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.
DEFINITIONS:
Accuracy/Bias (% Recovery) - The closeness of agreement between an observed value and an accepted reference value.
