A Site location map is included as Figure 1. The subject Site is comprised of seven parcels totaling approximately 5.89 acres. The Site contains four vacant commercial buildings, two occupied commercial buildings, one canopy structure, and two open carports. The commercial building located at 6128 Wilkinson Boulevard is currently occupied by a hair salon, and the commercial building located at 3000-B Little Rock Road is currently occupied by an automotive service and repair facility. The remainder of the Site is vacant. The Site has historically been used for residential and various commercial purposes including retail gasoline distribution, vehicle rental, automotive salvage, automotive sales and service, prefabricated building sales, hair salon, and general office space. The Site is planned to be redeveloped for office, hotel, retail and/or restaurant uses. The Site received eligibility into the North Carolina Department of Environmental Quality (DEQ) Brownfields Program via a Letter of Eligibility dated December 22, 2017. The Prospective Developer, RK Investments Charlotte LLC, subsequently elected to participate in the Brownfields Program Redevelopment Now option. As part of this process, a data gap meeting was held with the DEQ Brownfields project manager, Mr. Brad Atkinson, via telephone on January 10, 2018 to discuss the Site history, proposed redevelopment plans, previous assessment results, data gaps, and the proposed schedule for completing the Brownfields Agreement. H&H performed the 2 S:\AAA-Master Projects\RK Investments (RKI)\RKI-008 RK Investments Little Rock Road\Report\BF Assessment Report.docx Brownfields assessment activities presented in this report in accordance with a DEQ-approved Brownfields Assessment Work Plan (Work Plan) dated January 30, 2018 and follow up discussions with the Brownfields project manager. The Brownfields assessment activities were conducted to further evaluate potential risks associated with future Site development. The assessment activities included collection of soil and groundwater samples from the Site. A summary of Site history and previous assessment activities is included in Section 2.0, and the methods and results of the Brownfields assessment activities are presented in Sections 3.0 and 4.0. 3 S:\AAA-Master Projects\RK Investments (RKI)\RKI-008 RK Investments Little Rock Road\Report\BF Assessment Report.docx 2.0 Background Information The Site was undeveloped wooded land in the earliest historical resource reviewed, a 1938 aerial photograph. By 1951, the southeastern portion of the Site was developed for commercial purposes and the northeastern portion of the Site was developed with a residence. The Woodward Warren Company, a commercial refrigeration sales and service company, occupied the southeastern portion of the Site between at least 1956 and 1963. By 1964, the southeastern portion of the Site had transitioned into a gas station and automotive service facility. This portion of the Site was occupied by various gas station operators between 1964 and 1988. The southeastern portion of the Site has primarily been vacant since 1988, with periodic use for prefabricated building sales. By 1962, the northern portion of the Site transitioned into an automotive salvage yard and later to a used car dealership and automotive service and repair facility. Most recently, the northern portion of the Site contained a vehicle rental facility, an automotive sales and service operation, and various office tenants. Currently, automotive service and repair operations are conducted in the far northern portion of the property (addressed at 3000-B Little Rock Road). The southwestern portion of the Site was developed in 1974 with a commercial retail/office building. Various commercial tenants have occupied the southwestern portion of the Site, including a hair salon and landscape design company. Currently, a hair salon operates in the southwest portion of the Site (addressed at 6128 Wilkinson Boulevard). The former retail gas station and automotive repair facility located in the southeastern portion of the Site (6100-6108 Wilkinson Boulevard) was formerly known as the Little Rock Crown Service Station (1964) and Little Rock Phillips 66 Service Station (1969) (a.k.a. former Airport Automotive) and operated from approximately 1964 through 1988. Soil and groundwater impacts were identified at the subject Site as a result of the former Site gas station and automotive repair operations. According to our review of previous reports, the following underground storage tanks (USTs) were formerly present on the subject Site: 4 S:\AAA-Master Projects\RK Investments (RKI)\RKI-008 RK Investments Little Rock Road\Report\BF Assessment Report.docx • (3) 6,000-gallon gasoline USTs • (1) 4,000-gallon diesel UST • (1) 250-gallon heating oil UST • (1) 250-gallon waste oil UST • (2) approximately 1,000-gallon orphan gasoline USTs Soil and groundwater impacts were initially discovered at the Site during the removal of a 4,000- gallon diesel UST in December 1990 (Incident No. 6951). Subsequently, one 250-gallon heating oil UST and three 6,000-gallon gasoline USTs were removed from the Site in March 1992. Free phase product was observed in the tank basin at the time of removal and later free phase product was observed in monitoring wells at the Site. Reportedly, approximately 900 gallons of product and petroleum-impacted groundwater were removed from the tank basin and approximately 200 cubic yards of petroleum-impacted soil were removed for off-Site disposal at that time. Free phase product recovery efforts were conducted at the Site between 1992 and 2015 and included hand bailing, absorbent socks, and periodic aggressive fluid-vapor recovery (AFVR) events. Based on the observance of free phase product and the presence of six water supply wells within a 1,000 ft radius of the subject Site, DEQ classified the release incident as high risk. Municipal water connections were provided to the six properties in 2003 and 2004 and DEQ subsequently lowered the incident risk classification from high to intermediate risk. Source area soil remedial activities were conducted including the excavation and off-Site disposal of approximately 1,038 tons of petroleum-impacted soil from the former southern pump island in January 2014, and approximately 1,040 tons of petroleum-impacted soil at the former eastern pump island in August 2014. Excavation confirmation sample results indicated that two of the ten soil samples contained petroleum-related compounds at concentrations above the DEQ Inactive Hazardous Sites Branch (IHSB) Commercial/Industrial Health Based Preliminary Soil Remediation Goals (PSRGs). The two soil samples with compounds above Commercial/Industrial PSRGs were collected from the base of the excavation at the former southern pump island at depths of 15 ft and 17 ft below ground surface (bgs). Based on the depth of the base samples, it is unlikely that workers would disturb the petroleum-impacted soil during future redevelopment activities. 5 S:\AAA-Master Projects\RK Investments (RKI)\RKI-008 RK Investments Little Rock Road\Report\BF Assessment Report.docx A well network comprised of 20 monitoring wells and one recovery well were installed at the Site between 1992 and 2015. H&H reviewed the most recent groundwater monitoring report for the former Airport Automotive facility dated March 11, 2016. According to the report, benzene and 1,2-dichloroethane are present at concentrations exceeding DEQ Gross Contamination Levels (GCLs) in the southeastern portion of the Site. Additionally, a background monitoring well located near Little Rock Road indicates the southeastern portion of the Site has been impacted from a release incident associated with the east adjacent and hydraulically upgradient Airport Express gas station (Incident No. 36360). Free phase product has not been observed in monitoring wells at the Site since October 2015. Because extensive historical assessment activities have been conducted in the southern portion of the Site associated with the former gas station, the Brownfields assessment activities reported herein focused on the northern portion of the Site. 6 S:\AAA-Master Projects\RK Investments (RKI)\RKI-008 RK Investments Little Rock Road\Report\BF Assessment Report.docx 3.0 Brownfields Assessment Activities The assessment activities were performed in general accordance with DEQ – IHSB Guidelines for Assessment and Cleanup dated October 2015, and most recent version of the US Environmental Protection Agency (EPA) Region IV Science and Ecosystem Support (SESD) Field Branches Quality System and Technical Procedures guidance. As required by Mecklenburg County, H&H obtained a Subsurface Investigation Permit (SIP No. 70002495) from LUESA prior to installing temporary monitoring wells at the Site. Additionally, H&H obtained a Monitoring Well Construction Permit (Permit No. WM0300948) from DEQ Division of Water Resources prior to installing temporary monitoring wells at the Site. Copies of the well construction permits are provided in Appendix A. H&H conducted the Brownfields assessment activities at the Site on February 15 - 16, 2018. A discussion of the methods, analytical results, and conclusions of the Brownfields assessment activities are provided in the following sections. 3.1 Utility Clearance and Geophysical Survey Prior to conducting the Brownfields assessment activities, H&H contacted North Carolina 811 One-Call, the public utility locating service, to mark subsurface utilities at the Site. H&H also contracted a private utility locator, Sweetwater Utility Locating LLC (Sweetwater), to screen the proposed boring locations for subgrade utilities using ground-penetrating radar (GPR) and electromagnetic methods. Sweetwater also performed a GPR survey to confirm the presence of a UST associated with an apparent fill port observed along the west rear side of the former vehicle rental property building (3012 Little Rock Road). The results of the GPR survey confirmed the presence and orientation of the UST (see Figure 2). Sweetwater utilized a probe rod to determine that the top of the UST 7 S:\AAA-Master Projects\RK Investments (RKI)\RKI-008 RK Investments Little Rock Road\Report\BF Assessment Report.docx is approximately 1.5 ft bgs. The UST measures approximately 5.5 ft in length and approximately 4 ft in diameter. Therefore, the volume of the UST is estimated to be approximately 500-gallons. Based on the location and estimated volume of the UST, the tank is likely a non-regulated heating oil UST used to provide heat to the former vehicle rental building. The location of the UST is presented on Figure 2. 3.2 Soil Assessment H&H contracted with South Atlantic Environmental Drilling and Construction Company, Inc. (SAEDACCO) of Fort Mill, South Carolina to perform subsurface drilling activities utilizing a track-mounted GeoProbe® 7822DT direct push technology (DPT) drill rig. To assess the potential for soil impact, H&H advanced five soil borings (HHSB-1 through HHSB-5) at the Site. A summary of the soil boring locations is presented below: • Soil borings HHSB-1, HHSB-3, and HHSB-4 were advanced in the vicinity of historical automotive repair operations in the northeast portion of the Site. • Soil borings HHSB-2 and HHSB-5 were advanced in the vicinity of historical automotive salvage operations in the northern and east-central portions of the Site. Soil borings HHSB-3 and HHSB-5 were advanced in areas of observed surface staining. The locations of the soil borings are indicated on Figure 2. Additionally, two background soil samples were be collected to assess naturally occurring concentrations of metals in soil at the Site. The locations of the background soil borings were determined in the field and were collected from areas that did not appear to have been impacted from historical operations. The background soil borings were advanced in the undeveloped wooded portion of the Site near the western Site boundary (see Figure 2). 8 S:\AAA-Master Projects\RK Investments (RKI)\RKI-008 RK Investments Little Rock Road\Report\BF Assessment Report.docx Soil samples were collected using either a decontaminated stainless-steel hand auger or by DPT utilizing a decontaminated 5 ft long Macro-Core® sampler with disposable acetate liners. Following collection, soil samples were described for lithologic purposes, inspected for the presence of staining and odors, and field-screened for the presence of organic vapors with a calibrated photo-ionization detector (PID). Based upon field screening results, H&H collected one soil sample from each boring location for laboratory analysis. If there was field evidence of potential impacts, then the sample exhibiting the greatest potential for impact was submitted for laboratory analysis. If no evidence of potential impact was observed, then the soil sample for laboratory analysis was collected from within the upper five ft of soil column which is the area most likely to be disturbed during future redevelopment activities and/or most likely to pose a direct contact exposure concern. Boring logs with lithologic descriptions and field screening results are provided in Appendix B. Upon collection, the soil samples were placed directly into dedicated laboratory-supplied sample containers, labeled with the sample identification, date, and requested analysis, and placed in a laboratory supplied cooler with ice. The samples were shipped via overnight courier to TestAmerica Laboratories, Inc. (Test America) under chain-of-custody protocol for analysis of volatile organic compounds (VOCs) by EPA Method 8260, semi-VOCs (SVOCs) by EPA Method 8270, and the Resource Conservation and Recovery Act (RCRA) metals by EPA Methods 6020/7471 plus hexavalent chromium by EPA Method 7196. The RCRA metals include arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver. The background soil samples were analyzed for RCRA metals plus hexavalent chromium by EPA Methods 6020/7471/7196 only. 3.3 Groundwater Assessment To evaluate the potential for vapor intrusion into future Site buildings associated with groundwater impacts and to evaluate groundwater conditions in the northern portion of the Site, three temporary monitoring wells (HHTMW-1 through HHTMW-3) were installed and sampled for laboratory analysis. Additionally, three existing permanent monitoring wells (labelled MW-3 through MW- 9 S:\AAA-Master Projects\RK Investments (RKI)\RKI-008 RK Investments Little Rock Road\Report\BF Assessment Report.docx 5) in the northern portion of the Site were sampled for laboratory analysis. The temporary monitoring wells and existing monitoring well locations are depicted on Figure 2, the soil boring logs are presented in Appendix B, the well construction records are presented in Appendix C, and groundwater sampling records are presented in Appendix D. A summary of the temporary and existing monitoring well locations is presented below: • Temporary well HHTMW-1 was installed west and topographically downgradient of the UST to assess the potential for groundwater impacts from the former vehicle rental property building UST. • HHTMW-2 was installed in the north-central portion of the Site to assess the potential for groundwater impacts associated with historical automotive operations. • HHTMW-3 was installed west and topographically downgradient of the former automotive salvage operations in the HHSB-2 soil boring. • Existing monitoring well MW-3 is located east of the canopy structure in the vicinity of historical automotive salvage and repair operations. • Existing monitoring well MW-4 is located west and topographically downgradient of the former automotive salvage building located in the east-central portion of the Site. • Existing monitoring well MW-5 is located in the northwest portion of the Site, west and topographically downgradient of historical and current automotive repair operations. 10 S:\AAA-Master Projects\RK Investments (RKI)\RKI-008 RK Investments Little Rock Road\Report\BF Assessment Report.docx The temporary monitoring wells were advanced with a track-mounted GeoProbe® 7822DT drill rig utilizing DPT and hollow-stem auger (HSA) methods. The temporary monitoring wells were constructed using 1-inch diameter PVC riser with a 10-ft section of PVC screen set to bracket the shallow unconsolidated aquifer. At each temporary well, a sand filter pack was placed from the bottom of the boring to approximately two ft above the top of the well screen and a hydrated bentonite seal was placed from the top of the sand filter pack to the ground surface. Temporary well riser pipe was secured with a locked expansion plug. Upon installation, the temporary monitoring wells were allowed to equilibrate to static conditions and a decontaminated electronic water level indicator was used to measure the depth to the water table relative to the top of casing elevations in the temporary and existing monitoring wells. The measured depths to water in the wells ranged from approximately 22 ft bgs in the northern portion of the Site to approximately 18 ft bgs in the east-central portion of the Site. Prior to sampling, H&H developed the temporary monitoring wells by removing at least three well volumes using a peristaltic pump. After a minimum of three well volumes were purged, development was considered complete when field parameters of pH, conductivity, and oxidation reduction potential (ORP) stabilized and the water was visually clear. Following development, H&H collected groundwater samples from the temporary and existing monitoring wells for laboratory analysis on February 16, 2018 using low flow/low stress purging techniques with a peristaltic pump and dedicated polyethylene tubing. The intake point of the pump tubing was placed in the approximate mid-portion of the submerged portion of the well screen. A water quality meter was utilized to collect measurements of pH, temperature, dissolved oxygen, ORP, turbidity, and specific conductivity at 3 to 5-minute intervals during the purging process. Purging was considered complete when field parameters stabilized, and turbidity was less than 10 nephelometric turbidity units (NTUs). Final sample turbidity readings are presented on Table 2 and were all less than the 10 NTU. Groundwater sampling records are provided in Appendix D. 11 S:\AAA-Master Projects\RK Investments (RKI)\RKI-008 RK Investments Little Rock Road\Report\BF Assessment Report.docx The groundwater samples were collected directly into laboratory supplied sample containers using the “soda straw” method to minimize volatile loss during sampling. The sample containers were labeled with the sample identification, date, and requested analysis, placed in a laboratory supplied cooler with ice, and shipped via overnight courier under standard chain-of-custody protocol to TestAmerica for analysis of VOCs by EPA Method 8260, SVOCs by EPA Method 8270, and RCRA metals by EPA Methods 6020/7471 plus hexavalent chromium by EPA Method 7196. The temporary monitoring well and existing monitoring well locations were estimated using a sub- meter GPS unit. As requested by DEQ Brownfields, existing monitoring well MW-3 was gauged with an oil/water interface probe to determine the potential presence of free product in the well. The presence of free product was not detected in MW-3 during the gauging activities at the Site. 3.4 Quality Assurance/Quality Control H&H utilized standard quality assurance/quality control (QA/QC) processes during the Brownfields assessment activities. Non-dedicated sampling equipment, including DPT tooling, the water level meter, and the hand auger, were decontaminated using Liquinox® detergent and deionized water prior to and between each sampling location. H&H and SAEDACCO wore nitrile gloves while handling samples, and the groundwater samples were collected using dedicated tubing. Soil and groundwater samples were collected in laboratory-provided containers and placed on ice immediately after collection. For field and laboratory QA/QC purposes, H&H collected one duplicate soil sample from boring HHSB-3 and one duplicate water sample from existing monitoring well MW-3. The duplicate samples were analyzed for the same compounds as the parent samples. The results of analysis of the duplicate samples are provided in Tables 2 and 3 and indicate good analytical repeatability for the duplicate samples. 12 S:\AAA-Master Projects\RK Investments (RKI)\RKI-008 RK Investments Little Rock Road\Report\BF Assessment Report.docx Two laboratory-supplied trip blanks accompanied field personnel during groundwater sample collection activities and the VOC sample containers during shipment. The trip blanks were analyzed for VOCs by EPA Method 8260. There were no VOC detections in the trip blanks. 13 S:\AAA-Master Projects\RK Investments (RKI)\RKI-008 RK Investments Little Rock Road\Report\BF Assessment Report.docx 4.0 Brownfields Assessment Results The results of analysis of the groundwater samples are summarized in Table 2, and the results of analysis of the soil samples are summarized in Table 3. Laboratory analytical data reports and chain-of-custody records are included as Appendix E. 4.1 Soil Analytical Results In Table 3, the soil laboratory analytical results are compared to the DEQ IHSB Residential and Industrial/Commercial PSRGs dated February 2018. However, based upon the anticipated future use of the Site for commercial purposes, the discussion below focuses on comparison of the data to the Industrial/Commercial PSRGs. Metals concentrations were first compared to Site specific background levels before comparison to the PSRGs. VOCs Analytical results indicate that no VOCs were detected in any of the soil samples at concentrations exceeding Residential or Industrial/Commercial PSRGs. SVOCs Analytical results indicate that no SVOCs were detected in any of the soil samples at concentrations exceeding laboratory reporting limits. Metals The results of the metals analyses indicate that concentrations of arsenic were detected above laboratory reporting limits in each soil sample at concentrations ranging from 1.48 mg/kg to 4.13 mg/kg and generally within the range of Site-specific background concentrations (1.53 mg/kg to 1.91 mg/kg). One sample, HHSB-4, collected from north-central portion of the Site contained arsenic at a concentration 4.13 mg/kg, which is above the Industrial/Commercial PSRG of 3 mg/kg and slightly exceeds the background range. No other metals were detected above background and Industrial/Commercial PSRGs. 14 S:\AAA-Master Projects\RK Investments (RKI)\RKI-008 RK Investments Little Rock Road\Report\BF Assessment Report.docx 4.2 Groundwater Flow The temporary and existing monitoring well top of casing elevations were determined using survey methods to the nearest 0.01 ft and were referenced to an assumed datum of 100.00 ft at the HHTMW-1 top of casing. A summary of temporary well construction, the existing monitoring well construction data obtained from the well tags, and groundwater elevation data is presented on Table 1. A shallow unconsolidated aquifer potentiometric map generated from water table elevations is provided as Figure 3. As indicated on the figure, the general direction of shallow groundwater flow in the northern portion of the Site is to the west which is consistent with area topography. Depth to groundwater ranges from approximately 22 ft bgs in the far northern portion of the Site to approximately 18 ft bgs in the east-central portion of the Site. 4.3 Groundwater Analytical Results Laboratory analytical results were compared to the 15A North Carolina Administrative Code 02L.0202 Groundwater Quality Standards (2L Standards) and the DEQ DWM Groundwater Vapor Intrusion Screening Levels (VISLs). VOCs Analytical results indicate that no VOCs were detected at concentrations exceeding 2L Standards in any of the groundwater samples. VOCs Analytical results indicate that no SVOCs were detected in any of the groundwater samples at concentrations exceeding laboratory reporting limits. 15 S:\AAA-Master Projects\RK Investments (RKI)\RKI-008 RK Investments Little Rock Road\Report\BF Assessment Report.docx Metals Analytical results indicate the metal chromium (total) was detected in one sample (MW-5) at a concentration of 12.3 µg/L, which slightly exceeds the 2L Standard of 10 µg/L. Hexavalent chromium was not detected in the MW-5 sample. Additionally, the results indicate that elevated concentrations of barium were detected in temporary well HHTMW-1 (2,190 µg/L) and existing monitoring well MW-3 (1,740 µg/L) and its associated duplicate sample (1,780 µg/L) at concentrations exceeding the 2L Standard of 700 µg/L. HHTMW-1 and MW-3 are located in the far northeastern portion of the Site. As discussed in Section 3.3 above, field measurements of temperature, pH, conductivity, ORP, and turbidity were collected during the groundwater sampling event. Turbidity of the HHTMW- 1 and MW-3 samples was less than 10 NTU indicating that the elevated concentrations of barium are not likely associated with suspended sediment in the samples. However, the pH of the HHTMW-1 and MW-3 samples was low and in the range of 4.5 pH standard units (SU) versus the pH of the other samples collected at the Site (ranging from 5.9 SU to 6.6 SU). In addition, dissolved oxygen concentrations were generally lower in samples HHTMW-1 (0.93 mg/L) and MW-3 (0.39 mg/L) as compared to the other Site wells (ranging from 1.40 mg/L to 6.41 mg/L). The presence of lower pH and lower dissolved oxygen concentrations can lead to mobilization of naturally occurring metals such as barium in aquifer sediment. Although the source of the elevated barium in groundwater in the northeastern portion of the Site is not conclusively known, it is possible that naturally occurring low pH and low dissolved oxygen conditions may be present in this area of Site and may be contributing to the elevated barium concentrations in samples HHTMW-1 and MW-3. No other metals were detected at concentrations above 2L Standards. 16 S:\AAA-Master Projects\RK Investments (RKI)\RKI-008 RK Investments Little Rock Road\Report\BF Assessment Report.docx 5.0 Summary and Conclusions H&H completed Brownfields assessment activities at the Little Rock Road Brownfields property located 6108, 6120, and 6128 Wilkinson Boulevard and 3000 and 3012 Little Rock Road in Charlotte, Mecklenburg County, North Carolina. The Brownfields assessment activities were conducted to evaluate potential risks associated with future Site development. Because extensive historical assessment activities have been conducted in association with a former gas station in the southern portion of the Site, the Brownfields assessment activities focused on the northern portion of the Site. The Brownfields assessment activities included the collection of soil and groundwater samples for laboratory analysis. Based on the results of the assessment activities, H&H concludes the following: Soil • The analytical results of the soil samples indicate no VOCs or SVOCs were detected above Residential PSRGs. One metal, arsenic, was detected in each sample at concentrations above the Residential PSRG, but generally within the range of Site specific background levels (except HHSB-4). Arsenic was detected in one sample, HHSB-4 (4.13 mg/kg), located in the north-central portion of the Site, at a concentration slightly above background and the Industrial/Commercial PSRG of 3 mg/kg. Groundwater • Shallow groundwater flow in the northern portion of the Site is to the west which is consistent with Site topography. Depth to groundwater ranges from approximately 22 ft bgs in the far northern portion of the Site to approximately 18 ft bgs in the east-central portion of the Site. • The results of the groundwater assessment indicate that no VOCs or SVOCs were detected in groundwater from the monitoring wells in the northern portion of the Site. The metal chromium (total) was detected in one sample located in the far northern portion of the Site at a concentration slightly above the 2L Standard. In addition, elevated concentrations of 17 S:\AAA-Master Projects\RK Investments (RKI)\RKI-008 RK Investments Little Rock Road\Report\BF Assessment Report.docx barium were detected in two groundwater samples collected in the far northeastern portion of the Site at concentrations above the 2L Standard. Although the source of the barium is not known, it is possible that naturally occurring low pH conditions and low dissolved oxygen conditions may be present in this area of Site, which mobilized naturally occurring barium in the shallow unconsolidated aquifer. • Based on the lack of VOCs detected above vapor intrusion screening levels in groundwater from wells in the northern portion of the Site, vapor intrusion is not a significant concern for future buildings in the northern portion of the Site.

This report replaces the one generated on 02/23/18 @ 1242. Comments No additional comments. Receipt The samples were received on 2/17/2018 9:25 AM; the samples arrived in good condition, properly preserved and, where required, on ice. The temperatures of the 2 coolers at receipt time were 3.1º C and 4.7º C. GC/MS VOA Method 8260B: The laboratory control sample (LCS) and / or laboratory control sample duplicate (LCSD) for analytical batch 490-496192 recovered outside control limits for the following analytes: Bromomethane and Dichlorodifluoromethane. These analytes were biased high in the LCS and were not detected in the associated samples; therefore, the data have been reported. Method 8260B: The method blank for analytical batch 490-496192 contained 1,2,3-Trichlorobenzene above the reporting limit (RL). None of the samples associated with this method blank contained the target compound; therefore, re-extraction and/or re-analysis of samples were not performed. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. GC/MS Semi VOA Method 8270D: The laboratory control sample (LCS) and / or laboratory control sample duplicate (LCSD) for preparation batch 490-496205 and analytical batch 490-496272 recovered outside control limits for the following analytes: 4,6-Dinitro-2-methylphenol, Acenaphthylene, Benzo[b]fluoranthene, Carbazole, Fluoranthene, Phenanthrene, Pentachlorophenol and n-Nitrosodiphenylamine(as diphenylamine). These analytes were biased high in the LCS and were not detected in the associated samples; therefore, the data have been reported. Method 8270D: Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with preparation batch 490-496205 and analytical batch 490-496272. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. Metals No analytical or quality issues were noted, other than those described in the Definitions/Glossary page. General Chemistry Method 7196A: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for analytical batch 490-496732 were outside control limits. Sample matrix interference and/or non-homogeneity are suspected because the associated laboratory control sample (LCS) recovery was within acceptance limits. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. Organic Prep No analytical or quality issues were noted, other than those described in the Definitions/Glossary page. VOA Prep No analytical or quality issues were noted, other than those described in the Definitions/Glossary page.
