Monitoring Report April 27, 2023 Former Bob Mays Automotive Service ATC Project #SLC4431902 1 2.0 EXECUTIVE SUMMARY ATC Associates of North Carolina, P.C. (ATC) submits this Monitoring Report documenting soil and groundwater assessment activities conducted during January and February 2023 associated with the former Bob May’s Automotive Service Center site, located at 727 West Northwest Boulevard, in Winston-Salem, North Carolina. The approved activities included the installation of four new Type II monitoring wells, two new Type III monitoring wells, surface waer sampling, and a comprehensive groundwater monitoring event. The report has been completed based on a December 6, 2022, Task Authorization (TA-2) approved by the Trust Fund Branch of the Underground Storage Tank (UST) Section, Division of Waste Management, North Carolina Department of Environmental Quality (NCDEQ). Two Change Orders (#1 and #2) were approved on January 10, 2023 for additional services associated with the discovery of a landfill on the property and included the analysis of soil and groundwater for waste management and the off- site disposal of investigative derived waste (IDW). The work was performed as part of the State Lead Contract # N122019A between the NCDEQ and ATC. A former waste oil UST was removed on April 20, 2014, and during the removal the tank sparked and caught on fire. The NCDEQ was informed of the incident and based on reported staining on the tank, a release of was suspected. Monitoring well MW-1 was installed on November 17, 2015 at the location of a fomer waste oil UST. Tetrachloroethane [PCE, a chlorinated volatile organic compound (VOC)] were detected in the MW-1 sample at concentrations exceeding the 15A NCAC 02L groundwater quality standard (2L Standard) and the 15A NCAC 02B surface water quality standard (2B Standard). Other chlorinated VOCs were reported at concentrations less than the 2L Standards and 2B Standards. Petroleum volatile organic compounds (VOCs) were not detected in the MW-1 sample at concentrations exceeding the 2L Standards or the 15A NCAC 02B surface water quality standards (2B Standards). This assessment was conducted to evaluate the extent of the chlorinated VOCs for possible closure of the incident. Based on field activities conducted by ATC in January and February 2023 and previous assessment activities, the site conditions are summarized below:  No water supply wells are located within 1,000 feet of the source area;  One surface water body (Peters Creek, a Class C stream) is located within 500 feet north- northeast of the source area;  New monitoring wells MW-2, MW-2D, MW-3, MW-3D, MW-4, and MW-5 were installed on the site property in January 2023;  Groundwater samples were collected from monitoring wells MW-1, MW-2, MW-2D, MW-3, MW-3, MW-3D, MW-4, and MW-5 on January 11 and 12, 2023;  Light Non-Aqueous Phase Liquid (LNAPL) was not detected in the monitoring wells during the groundwater monitoring event;  No volatile organic compounds (VOCs) were reported in the monitoring well samples at concentrations exceeding the Gross Contamination Levels (GCLs);  PCE was detected above the 2L Standard and the 2B Standard in monitoring well MW-1 (115 microgram per liter or µg/L);  Trihalomethanes bromodichloromethane (3.0 µg/L) and dibromochloromethane (0.80 µg/L) were reported in MW-3D at concentrations above their respective 2L Standards. Chloroform was also reported in MW-3D at a concentration less than the 2L Standard. These three VOCs may be associated with city water used for the drilling activities;  Excluding the trihalomethanes in MW-3D, VOCs were not detected above the 2L Standards or 2B Standards in wells MW-2, MW-2R, MW-3, MW-3D, MW-4, or MW-5;  Groundwater flow is estimated to be to the northwest towards Peter’s Creek. Monitoring Report April 27, 2023 Former Bob Mays Automotive Service ATC Project #SLC4431902 2  The depth to groundwater in the shallow monitoring wells ranged from 14.28 feet below top of casing (ft-toc) in MW-1 to 16.52 ft-toc in MW-2.  Bedrock was not encountered to a depth of approximately 50 feet below ground surface (ft- bgs).  Surface water samples were not collected due to the inability to access the stream from the south side due to slopes, vegetation and debris, or from the north side due to the inability to obtain access agreements with the property owners adjoining the site property;  Buried debris was identified during drilling activites for wells MW-2, MW-2D, MW-3, MW- 3D, and MW-4. The area of these wells was determined to be a former landfill. Debris (e.g., concrete) was observed along the bank of Peters Creek. Analysis of soil and groundwater samples for waste characterization indicated the waste to be non-hazardous. No VOCs, semi-volatile organic compounds (SVOCs), Appendix IX metal, dioxins, or furans were reported above the NCDEQ, Division of Waste Management, Inactive Hazardous Site Branch’s (IHSB) Preliminary Soil Remediation Goals (PSRGs), except for methylene chloride and cobalt exceeding the Protection of Groundwater PRSGs and arsenic exceeding the Residential PSRG. The PCE detected in monitoring well MW-1 does not appear to have migrated to the property boundaries or to Peters Creek. Based on the site conditions decribed above, ATC presents the following recommendations:  Close the UST incident 44319 and abandon the monitoring wells.  Report the results to the IHSB for further evaluation of subsequent actions that may be required relating to the discovered landfill. 3.0 SITE DESCRIPTION 3.1 Site Characterization ATC, under contract to the NCDEQ, provided environmental consulting services at the former Bob May’s Automotive Service Center site, located at 727 West Northwest Boulevard, in Winston- Salem, North Carolina. Figure 1 depicts the site loctaion on a topographic map. The site formerly operated as a auto repair facility, but is currently vacant. Based on information obtained during a receptor survey conducted in 2016, there are no water supply wells located within 1,000 feet of the site and one surface water body (Peters Creek, a Class C stream) is located within 500 feet north-northeast of the source area. 3.2 Site Background The former Bob May’s Automotive Service Center facility (the Site) is located at 727 West Northwest Boulevard, in Winston-Salem, North Carolina. A February 2, 2016 Phase I Limited Site Assessment Report, prepared by S&ME, Inc. for the NCDEQ included the results of soil and groundwater sampling (from one location, boring and monitoring well MW-1) and a receptor survey. The assessment was performed due to a former 2,000-gallon waste oil UST. The site conditions are presented below:  No water supply wells are located within 1,000 feet of the source area.  One surface water body (Peters Creek) is located within 500 feet north-northeast of the source area.  The depth to groundwater was approximately 14 feet below ground surface, and based on topography, groundwater flow is expected to flow to the north-northeast. Monitoring Report April 27, 2023 Former Bob Mays Automotive Service ATC Project #SLC4431902 3  No exceedances of the Maximum Soil Contaminant Concentrations (MSCCs) were identified in the soil.  No exceedances of the GCLs were identified in the groundwater.  PCE was detected in the groundwater at a concentration of 75 micrograms per liter (µg/L), that exceeded the 2L Standard of 0.7 µg/L. No other contaminants were reported at concentrations exceeding the 2L Standards. On October 25, 2021, Withers & Ravenel sampled monitoring well MW-1, and the results confirmed the presence and concentration of PCE at 74.3 µg/L. On July 5 and 6, 2022, ATC conducted passive soil gas (PSG) sampling at the site for the purposes of evaluating the potential source of the tetrachloroethene reported in the groundwater. ATC installed twenty-three Beacon Samplers (PSG-1 through PSG-23). After installation, the PSG Beacon Samplers remained in-place for at least 14 days prior to retrieval. On July 19-20, 2022, ATC returned to retrieve the PSG samplers. Multiple VOCs were reported in the PSG samples. None of the VOC concentrations exceeded the established Non-Residential VISLs, except for the Total Petroleum Hydrocarbons (TPH) C4-C9 and C10-C15. Of note, the highest concentrations of PCE, trichloroethylene (TCE), and 1,1,1-trichloroethane (1,1,1-TCA) were reported in the two samples nearest the former waste oil UST (samples PSG- 8 and PSG-11). VOC concentrations reported in the remaining PSG samples were much lower than those detected in PSG-8 and PSG-11, including results reported as non-detects. The location of the site and surrounding topography is depicted on Figure 1. The layout of the site, the approximate location of existing monitoring well MW-1, and the approximate location of the former waste oil UST is presented on Figure 2. 3.3 Site and Regional Geology According to the Geologic Map of North Carolina (1985), According to the 1985 USGS Geologic Map of North Carolina, and the 2016 LSA submitted by S&ME, the site is underlain by the Milton Belt of the Piedmont Physiographic Province. Bedrock in this area is biotite gneiss and schist. These are rocks that are inequigranular and megacrystic, with abundant potassic feldspar and garnet. They are interlayered and gradational with calcsilicate rock, sillimanite-mica schist, mica schist, and amphibolite. It also contains small masses of granitic rock. Boring logs from recent shallow monitoring well installation activities conducted at the site indicate that the site subsurface generally consists of light red to red-brown and tan to brown interbedded layers of clay, silt, and silty clay to a depth of approximately 15 ft-bgs, and tan to brown clay to clayey-silt 15 to 25 ft-bgs. Soils observed during the installation of the deep wells indicated soils at depth consisted primarily of tan silt from approximately 35 to 50 ft-bgs. Bedrock was not encountered to a depth of 50 ft-bgs. 3.4 Site and Regional Hydrogeology The shallow aquifer occurrence varies in depth from ground surface at springs, creeks, and rivers to as deep as 50 feet or more beneath upland surfaces in some parts of the Piedmont. Water in the alluvium or unconsolidated residual material, including saprolite and PWR, usually behaves as an unconfined aquifer, or water table, and will yield water with head elevation equivalent to the first elevation where water was encountered. Permeability varies with lithology and is typically Monitoring Report April 27, 2023 Former Bob Mays Automotive Service ATC Project #SLC4431902 4 relatively low in residual soils, with higher permeability in saprolite or PWR due to relict rock texture and variable susceptibility to weathering exhibited by different minerals in the rock. Groundwater flow in residual soils or alluvium is usually in rough concurrence with local topographic conditions and is toward local drainage features. The bedrock fractures or other planar features of the Piedmont generally constitute the bedrock aquifer, with the surrounding rock material being effectively impermeable. Along with fractures, contacts between rock bodies probably constitute zones of significant groundwater occurrence in the bedrock. The surrounding material and overlying residuum tend to make the bedrock aquifer a semi-confined aquifer. That is, the overlying water and soil weight normally results in pressure that causes water in a borehole, which intersects a fracture or other feature, to rise above the elevation of the fracture or feature. Modern water supply wells in the Piedmont are typically installed with a surface casing through the unconsolidated material, and an open borehole into the bedrock where water-bearing fractures are encountered. The January 11, 2023 depths to groundwater in the shallow wells ranged from 14.28 ft-toc in well MW-1 to 16.52 ft-toc in well MW-2. Based on calculated groundwater elevations, the shallow horizontal gradient was approximately 0.022 feet per foot to the northwest towards Peters Creek. Groundwater elevations in the pair shallow and deep and MW-3/MW-3d, indicated an upward vertical gradient for monitoring wells MW-2/MW-2D and a slight downward gradient for monitoring wells MW-3/MW-3D. 4.0 POTENTIAL RECEPTORS A February 2, 2016 Phase I Limited Site Assessment Report, prepared by S&ME, Inc. for the NCDEQ included the results of soil and groundwater sampling (from one location, boring and monitoring well MW-1) and a receptor survey. The assessment was performed due to a former 2,000-gallon waste oil UST. The site conditions are presented below:  No water supply wells are located within 1,000 feet of the source area.  One surface water body (Peters Creek) is located within 500 feet north-northeast of the source area. No other potential receptors were identified within 500 feet of the Site. 5.0 GROUNDWATER ASSESSMENT ACTIVITIES 5.1 Monitoring Well Installation Between January 3 and 10, 2023, ATC supervised the installation of monitoring wells MW-2, MW- 2D, MW-3, MW-3D, MW-4, and MW-5. The locations of the wells are indicated on Figure 2. ATC contracted with SAEDACCO, a North Carolina certified well contractor, to drill the borings and install the monitoring wells. The borings for the shallow monitoring wells were extended to depths of approximately 25 ft-bgs using 4.25-inch inner diameter (ID) hollow stem augers (HSAs), with screened intervals of 10 to 25 ft-bgs. The borings for the deep wells MW-2D and MW-3D were drilled using 10-inch inner diameter HSAs with 6-inch diameter schedule 40 PVC casing set to depths of approximately 35 and 38 ft-bgs, respectively. The deep well borings for wells MW-2D and MW-3D were extended to depths of approximately 50 and 47 ft-bgs using a 6-inch nominal mud-rotary bit, with screen intervals of 47 to 50 ft-bgs for well MW-2D and 42 to 47 ft-bgs for well MW-3D. Monitoring Report April 27, 2023 Former Bob Mays Automotive Service ATC Project #SLC4431902 5 The monitoring wells were were constructed of 2-inch diameter, Schedule 40 PVC screen (0.010- inch slots) and Schedule 40 PVC riser to near land surface. Filtered sand was installed within the annulus to approximately 2-feet above the top of the screens, with approximately 2-feet of bentonite above the sand pack, and grout to near land surface. Each well was completed with a 2-foot-by-2-foot concrete pad, 8-inch diameter well vault, and capped with a lockable water-tight cap. The Type II monitoring wells were developed by SAEDACCO, utilizing a submersible Monsoon pump and new tubing, by purging groundwater until turbidity was visibly reduced. All IDW (soil cuttings, well development water, well purge water, and plastic used for the decontamination of drilling equipment) was contained in 55-gallon drums. Samples of the contained soil and water were collected and analyzed for waste characterization, as further discusses in Section 6.0, Waste Management. On February 1, 2023 (during the removal of the drummed IDW), ATC measured the top of casing elevations of the new wells relative to monitoring well MW-1. Field notes of the field activities are presented in Appendix A. Well construction records and wells logs with soil descriptions are included in Appendix B. 5.2 Groundwater Levels On January 11, 2023, ATC measured the depth to groundwater in monitoring wells MW-1, MW- 2, MW-3, MW-4, MW-5, MW-2D, and MW-3D. LNAPL was not identified in the monitoring wells. The depths to groundwater in the shallow wells ranged from 14.28 ft-toc in well MW-1 to 16.52 ft- toc in well MW-2. Groundwater elevations ranged from 86.26 feet in MW-5 to 82.79 feet in MW-2 (3.47 feet elevation difference). Based on these measurements, the shallow horizontal gradient is calculated to be approximately 0.022 feet per foot to the northwest towards Peters Creek. The groundwater elevations of MW-2 (82.79) and MW-2D (83.24) indicate an upward vertical gradient. The groundwater elevations of MW-3 (83.38) and MW-3D (83.35) indicate a slight downward vertical gradient. A summary of monitoring well construction and water level elevation data is provided in Table 1. A map depicting groundwater elevations and estimated flow is provided as Figure 3. Field notes of the January 11, 2023, groundwater monitoring event are presented in Appendix A. 5.3 Groundwater Quality On January 11, 2023 and January 12, 2023, groundwater samples were collected from monitoring wells MW-1, MW-2, MW-2D, MW-3, MW-3, MW-3D, MW-4, and MW-5. At least three standing well volumes were purged from the monitoring wells, or purged until dry and allowed to recharge, prior to groundwater sample collection to ensure a representative sample was collected. After purging and prior to collecting groundwater samples, water quality parameters were measured. Water quality parameters recorded prior to sample collection are included in Table 2. The water samples were collected in laboratory-supplied, preserved containers; entered into chain-of-custody control; placed on ice; and delivered to North Carolina-accredited Pace Analytical (Pace) in Huntersville, North Carolina. A field blank was also collected and submitted for laboratory analysis. The groundwater samples and field blank were analyzed for VOCs by Standard Method 6200B. Groundwater samples from the shallow monitoring wells within the Monitoring Report April 27, 2023 Former Bob Mays Automotive Service ATC Project #SLC4431902 6 landfill area (MW-2, MW-3, and MW-4) were also analyzed for TCLP RCRA Metals for disposal purposes as discussed in Section 6.0, Waste Management. The analytical report is included as Appendix C. The January 2023 groundwater analytical results are summarized in Table 3. This includes the SM 6200B VOCs and the TCLP RCRA Metals. Six chlorinated VOCs were detected in monitoring well MW-1, and the concentrations of those VOCs for each well are presented on Figure 4. The groundwater analytical results were compared to 2L Standards, 2B Standards, and GCLs. Groundwater analytical results from the January 2023 sampling event indicated the following:  VOC concentrations did not exceed the GCLs;  Three VOCs were reported in the sample from MW-3D: trihalomethanes chloroform (less than the 2L Standard) and bromodichloromethane and dibromochloromethane (above the 2L Standards). These VOCs may be the mud-rotary drilling activities that utilized municipal water;  PCE (115 µg/L) was reported in MW-1 at a concentration that exceeds the 2L Standard and the 2B Standard (0.7 µg/L for both). The PCE concentration increased by approximately 55% from the October 25, 2021 sample results; and  VOCs were not reported in wells MW-2, MW-2D, MW-3, MW-3, MW-3D, MW-4, and MW- 5 above the 2L Standards (excluding the trihalomethanes in MW-3D) or 2B Standards. As part of ATC’s quality assurance and quality control (QA and QC) measures, a data review of the laboratory report was conducted. During the review, it was found that the samples were received from the laboratory in acceptable condition and properly preserved. The chain-of- custody was properly completed by all parties. The samples were analyzed within correct holding times and reported within the lab report. The laboratory QC reports show that internal blanks were analyzed for the requested analytical methods for the groundwater samples submitted. The laboratory fortified blank (LFB) and laboratory control sample (LCS) data results were also provided for the requested analytical methods. A field blank (FB) was also collected during the groundwater monitoring event and analyzed for VOCs by EPA Method 6200B. Laboratory analysis of the field blank did not indicate VOCs above laboratory method detection limits. Refer to the laboratory report in Appendix C for details regarding QA results for the laboratory samples and any noted exceptions. Overall, ATC concludes that the laboratory results are usable and any exceptions do not significantly impact the conclusions presented in this report. 6.0 WASTE MANAGEMENT Due to the drilling through landfill debris that was unknown and uncharacterized, ATC collected composite soil samples of the soil cuttings from the depths of 0 to 10 ft-bgs and greater than 10 ft-bgs. The analyses included VOCs by EPA Method 8260 for both samples. The >10-foot sample was also analyzed for pesticides by EPA Method 8081, Appendix iX herbicides by Method SW8151, polychlorinated biphenyls (PCBs by EPA Method 8082, Appendix IX Metals by EPA Mehods 6010/7471, SVOCs by EPA Method 8270, sulfides by SM 4500S2D, cyanide by SM 4500CNE, and for dioxins and furans [polychlorodibenzo-p-dioxins (PCDDs) and polychlorodibenzofurans (PCDFs)] for the >10-ft sample by EPA Method 8290. The results are summarized below, and presented in Table 4. Monitoring Report April 27, 2023 Former Bob Mays Automotive Service ATC Project #SLC4431902 7  0-10-ft-bgs sample: VOCs (naphthalene, toluene, p-isopropyltoluene, and PCE) were reported at concentrations less than the lowest PSRG.  1>10-ft-bgs sample: o Pesticides, herbicides, PCBs, SVOCs, sulfide, cyanide, and furans were not detected. o One VOC (methylene chloride) was reported at an estimated concentration of 0.026 milligrams per kilogram (mg/kg) that exceeding the Protection of Groundwater PSRG of 0.025 mg/kg. o Two metals were reported at concentrations exceeding the Residential PSRG (arsenic at 1.1 mg/kg) and the Protection of Groundwater PSRG (cobalt at 4.4 mg/kg). o Dioxin (total HxCDD) was reported at a concentration of 2.9x10-6 mg/kg, less than the lowest PSRG of 1.0x10-4 mg/kg. Based on the soil samples results, water samples from wells MW-2, MW-3, and MW-4 were also analyzed for RCRA Metals following the TCLP method for waste characterization. Barium was reported in all three samples and cadmium was reported in the MW-4 sample (Table 3). The concentrations were less than the hazardous waste limits. Copies of the laboratory reports are included in Appendix C. Copies of the waste profiles for the IDW (solids, water, and plastic) are included in Appendix D. On February 1, 2023, A&D Environmental removed the drummed IDW: nine drums of liquid, 25 drums of solid/drilling mud, and one drum of plastic waste. A&D Environmental transported the waste to their Archdale, North Carolina facility. A copy of the “Bill of Lading / Material Manifest” is also included in Appendix D. 7.0 CONCLUSIONS AND RECOMMENDATIONS ATC Associates of North Carolina, P.C. (ATC) submits this Monitoring Report documenting soil and groundwater assessment activities conducted during January and February 2023 associated with the former Bob May’s Automotive Service Center site, located at 727 West Northwest Boulevard, in Winston-Salem, North Carolina.  No water supply wells are located within 1,000 feet of the source area;  One surface water body (Peters Creek, a Class C stream) is located within 500 feet north- northeast of the source area;  New monitoring wells MW-2, MW-2D, MW-3, MW-3D, MW-4, and MW-5 were installed on the site property in January 2023;  Groundwater samples were collected from monitoring wells MW-1, MW-2, MW-2D, MW-3, MW-3, MW-3D, MW-4, and MW-5 on January 11 and 12, 2023;  LNAPL was not detected in the monitoring wells during the groundwater monitoring event;  No VOCs were reported in the monitoring well samples at concentrations exceeding the GCLs;  PCE was detected above the 2L Standard and the 2B Standard in monitoring well MW-1 (115 µg/L);  Trihalomethanes bromodichloromethane (3.0 µg/L) and dibromochloromethane (0.80 µg/L) were reported in MW-3D at concentrations above their respective 2L Standards. Chloroform was also reported in MW-3D at a concentration less than the 2L Standard. These three VOCs may be associated with city water used for the drilling activities; Monitoring Report April 27, 2023 Former Bob Mays Automotive Service ATC Project #SLC4431902 8  Excluding the trihalomethanes in MW-3D, VOCs were not detected above the 2L Standards or 2B Standards in wells MW-2, MW-2R, MW-3, MW-3D, MW-4, or MW-5;  Groundwater flow is estimated to be to the northwest towards Peter’s Creek.  The depth to groundwater in the shallow monitoring wells ranged from 14.28 ft-toc in MW-1 to 16.52 ft-toc in MW-2.  Bedrock was not encountered to a depth of approximately 50 ft-bgs.  Surface water samples were not collected due to the inability to access the stream from the south side due to slopes, vegetation and debris, or from the north side due to the inability to obtain access agreements with the property owners adjoining the site property;  Buried debris was identified during drilling activites for wells MW-2, MW-2D, MW-3, MW- 3D, and MW-4. The area of these wells was determined to be a former landfill. Debris (e.g., concrete) was observed along the bank of Peters Creek. Analysis of soil and groundwater samples for waste characterization indicated the waste to be non-hazardous. No VOCs, SVOCs, Appendix IX metal, dioxins, or furans were reported above the NCDEQ, Division of Waste Management, Inactive Hazardous Site Branch’s Preliminary Soil Remediation Goals (PSRGs), except for methylene chloride and cobalt exceeding the Protection of Groundwater PRSGs and arsenic exceeding the Residential PSRG.

This report presents the results from the analysis performed on one sample submitted by a representative of Pace Analytical Services, LLC. The sample was analyzed for the presence or absence of polychlorodibenzo-p-dioxins (PCDDs) and polychlorodibenzofurans (PCDFs) using a modified version of USEPA Method 8290. The estimated detection limits (EDLs) were based on signal-to-noise measurements. Estimated maximum possible concentration (EMPC) values were treated as positives in the toxic equivalence calculations. The isotopically-labeled PCDD/PCDF internal standards in the sample extract were recovered at 50-103%. All of the labeled internal standard recoveries obtained for this project were within the 40-135% target range specified in Method 8290. Since the quantification of the native 2,3,7,8-substituted congeners was based on isotope dilution, the data were automatically corrected for recovery and accurate values were obtained. Values were flagged "I" where incorrect isotope ratios were obtained or "P" where polychlorinated diphenyl ethers were present. Concentrations below the calibration range were flagged "J" and should be regarded as estimates. A laboratory method blank was prepared and analyzed with the sample batch as part of our routine quality control procedures. The results show that PCDDs and PCDFs were not detected. A laboratory spike sample was also prepared with the sample batch using clean reference matrix that had been fortified with native standard materials. The results show that the spiked native compounds were recovered at 95-121%. These results were within the target range for the method. Matrix spikes were prepared with the sample batch using sample material from a separate project; results from these analyses will be provided upon request. The response obtained for the labeled OCDD in calibration standard analysis U230116A_20 was outside the target range. As specified in our procedures for this method, the average of the daily response factors for this compound was used in the calculations for the samples from this runshift. The affected values were flagged "Y" on the results tables.

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPAMethod 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited.

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPAMethod 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited.
