Regarding wells screened within the uppermost portion of the aquifer underlying the facility, the elevation of the water table was found to vary from a high of 512.74 feet above mean sea level at upgradient monitoring well 6801-MW110S to a low of 477.69 feet above mean sea level at downgradient monitoring well 6801-MW104. A comparison of static water elevations obtained during the referenced sampling event with those obtained during prior sampling events reveals no hydrogeologically significant changes in directions of groundwater flow.

are transported in groundwater may be conservatively estimated by the velocity of groundwater flow. We shall distinguish between the apparent Darcy groundwater flow velocity (Vd) and seepage velocity (Vs), which are given by the equations: Vd = ki and Vs = kin-1 where: Vd = Darcy velocity Vs = seepage velocity k = hydraulic conductivity i = hydraulic gradient n = porosity Hydraulic parameters for wells associated with the subject facility are summarized in the hydraulic parameters table provided at the end of this ATTACHMENT. Effective porosity values are estimated to range from about 15% (bedrock) to 35% (saprolite). Using groundwater elevations measured during the subject sampling event, the hydraulic gradient of the uppermost aquifer was calculated along the flow path from well 6801-MW110S to well 6801- MW104. The average hydraulic gradient was estimated by dividing the difference between the hydraulic heads (elevation heads) in well 6801-MW110S and well 6801-MW104 by the distance between those two wells (about 1,881 feet). The hydraulic conductivity value derived from well 6801-MW104 (1.80 x 10-5 m/sec) was used to calculate groundwater velocity along the flow path from well 6801-MW110S to well 6801-MW104 (being the higher conductivity observed in that particular pair of wells). Calculated velocities (along the selected flow path) are presented in the groundwater velocity calculations table at the end of this ATTACHMENT and illustrated on the accompanying graph. The velocity observed during the subject sampling event (231.5 feet per year) was 8.3% less than the median velocity (252.4 feet per year along the selected flow path). A review of groundwater velocity over time, commencing in May 2011 (see graph), indicates that velocity generally increased, between late 2011 and early 2014, after which it has generally oscillated around the median velocity along the selected flow path. Groundwater Monitoring Program March 2024 Results of Sampling and Analysis Attachment 4 Sampling Event 59: 11.20.23 to 11.22.23 OCSWM South Facility, Permit No. 68-01 Page 2 We note that the calculated groundwater velocity along a given flow path represents an average velocity along one of many potential flow paths in the uppermost aquifer underlying the area of interest. Nonetheless, the velocity estimate is believed to be reasonably representative of that area.

Information presented on the certificates can be summarized as follows: We have received copies of the certificates-of-analysis (dated December 4-6, 2023). During event 59, The laboratory did not detect any organic constituents in groundwater at the subject facility. Discussion. During all sampling events, through event 25 (except event 12 [May 2000], during which the reported occurrence of toluene in one upgradient well was deemed unreliable), the laboratory did not detect any organic constituents in groundwater at the subject facility. However, beginning with the June 2007 sampling event, the laboratory began to observe several volatile organic compounds in several monitoring wells: benzene carbon disulfide chlorobenzene chloroethane cis-1,2-dichloroethene 1,1-dichloroethane trichloroethene vinyl chloride The laboratory was not able to quantify (<MRL) the concentrations of most occurrences, and a considerable majority of the reported occurrences pertained to a single well (6801-MW105). Maximum concentrations of volatile organic constituents in well 6801-MW105 were observed during 2012, after which concentrations began decreasing. By May 2014, the laboratory no longer detected any volatile organic constituents in well 6801- MW105. During the November 2023 event, Semi-volatile organics (SVOCs) (Method 8270E), PCBs (Method 8082A) and pesticides (Method 8081B) were analyzed from the sample obtained from MW-105. No detections of pesticides, SVOCs or PCBs were reported in the November 2023 analytical results. In response to the initial occurrences of volatile organic constituents in well 6801-MW105, OCSWM constructed well 6801-MW112 at a location that is approximately 190 feet downgradient of well 6801-MW105. Groundwater Monitoring Program March 2024 Results of Sampling and Analysis Attachment 5 Sampling Event 59: 11.20.23 to 11.22.23 OCSWM South Facility, Permit No. 68-01 The laboratory has reported only trace levels (always less than 1 ppb) of several volatile organic constituents in well 6801-MW112. By May 2013, the laboratory no longer reliably detected any volatile organic constituents in well 6801-MW112 and there were no detections in November 2023.

Groundwater samples to be analyzed for metals were not filtered in the field, such that all metals were analyzed as total metals. We have received copies of the certificates-of-analysis (dated December 4-6, 2023). Information presented on the certificates are summarized as follows: During event 59, the laboratory detected eight inorganic constituents (metals), at concentrations greater than their respective method detection limits (>MDLs): arsenic, barium, cobalt, copper, iron (C&D parameter), nickel, vanadium and zinc. Of the eight inorganic constituents detected (>MDL), the laboratory was able to quantify (>MRL) the concentrations of all eight inorganic constituents: arsenic, barium, cobalt, copper, iron, nickel, vanadium and zinc which are included in this summary. Of the eight inorganic constituents that the laboratory were able to quantify (>MRL), the concentrations of five constituents exceeded their respective Regulatory Protection Standard (2L or FBAC). The reported concentration of arsenic in wells 6804-MW105 (33.0 µg/L) exceeded its Facility Background Concentration (15.66 ug/L) and its Groundwater Quality Standard (10 µg/L). The reported concentration of arsenic in well 6804-MW110D (14.0 µg/L) exceeded its Groundwater Quality Standard (10 µg/L). As discussed below, an Alternate Source Demonstration (ASD) was approved for arsenic during September 2011. The reported concentration of cobalt in well MW105 (25.8 µg/L) exceeded its Facility Background Concentration (2.15 µg/L) and its Groundwater Quality Standard (1.0 µg/L). As discussed below, an Alternate Source Demonstration (ASD) was approved for cobalt during March 2011. The reported estimated concentration of nickel in wells 6804-MW101(5.5 µg/L) 6804- MW105 (8.6 µg/L) and 6804-MW111 (6.5 µg/L) exceeded its Facility Background Concentration (2.688 µg/L) but not their Groundwater Quality Standard (100 µg/L). The reported concentration of vanadium in well 6804-MW111 (7.6 µg/L), exceeded its Groundwater Quality Standard (0.3 µg/L), and the Facility Background Concentration (6.968 µg/L) As discussed below, an Alternate Source Demonstration (ASD) was approved for vanadium during March 2011. Groundwater Monitoring Program February 2024 Results of Sampling and Analysis Attachment 6 Sampling Event 59: 11.20.23 to 11.22.23 OCSWM South Facility, Permit No. 68-01 Page 2 The reported concentration of zinc in well 6804-MW101 (24.9 µg/L), exceeded its Facility Background Concentration (22.83 µg/L) but not its Groundwater Quality Standard (1,000 µg/L). Alternate Source Demonstrations. As summarized below, OCSWM has prepared Alternate Source Demonstrations to address apparent exceedances of several metals at one or more of the three solid waste management units (North, South, C&D). The following Alternate Source Demonstrations pertained to the South landfill: Cobalt. OCSWM submitted an Alternate Source Demonstration showing that total cobalt observed in groundwater at the site could have been derived from onsite soils. In a letter from NCDEQ to OCSWM (dated March 30, 2011), NCDEQ approved the Alternate Source Demonstration. In accordance with the approved Alternate Source Demonstration, the reported exceedances of total cobalt may be attributed to the naturally occurring presence of cobalt in onsite soils. Vanadium. OCSWM submitted an Alternate Source Demonstration showing that total vanadium observed in groundwater at the site could have been derived from onsite soils. In a letter from NCDEQ to OCSWM (dated May 26, 2010), NCDEQ approved the Alternate Source Demonstration. In accordance with the approved Alternate Source Demonstration, the reported exceedances of total vanadium may be attributed to the naturally occurring presence of vanadium in onsite soil and rock. The following Alternate Source Demonstrations pertained to the North landfill: Arsenic. OCSWM submitted an Alternate Source Demonstration (dated September 2, 2011), showing that total arsenic observed in groundwater at the facility could have been derived from onsite soils. In a letter from NCDEQ to OCSWM (dated September 26, 2011), NCDEQ approved the Alternate Source Demonstration. In accordance with the approved Alternate Source Demonstration, the reported exceedances of total arsenic may be attributed to the naturally occurring presence of arsenic in onsite soils. Cobalt. OCSWM submitted an Alternate Source Demonstration (dated September 2, 2011), showing that total cobalt observed in groundwater at the facility could have been derived from onsite soils. In a letter from NCDEQ to OCSWM (dated September 26, 2011), NCDEQ approved the Alternate Source Demonstration. In accordance with the approved Alternate Source Demonstration, the reported exceedances of total cobalt may be attributed to the naturally occurring presence of cobalt in onsite soils. Lead. OCSWM submitted an Alternate Source Demonstration (dated September 2, 2011), showing that total lead observed in groundwater at the facility could have been derived from onsite soils. In a letter from NCDEQ to OCSWM (dated September 26, 2011), NCDEQ approved the Alternate Source Demonstration. In accordance with the approved. Alternate Source Demonstration, the reported exceedances of total lead may be attributed to the naturally occurring presence of lead in onsite soils. Groundwater Monitoring Program February 2024 Results of Sampling and Analysis Attachment 6 Sampling Event 59: 11.20.23 to 11.22.23 OCSWM South Facility, Permit No. 68-01 Page 3 Selenium. OCSWM submitted an Alternate Source Demonstration (dated September 2, 2011), showing that total selenium observed in groundwater at the facility could have been derived from onsite soils. In a letter from NCDEQ to OCSWM (dated September 26, 2011), NCDEQ approved the Alternate Source Demonstration. In accordance with the approved Alternate Source Demonstration, the reported exceedances of total selenium may be attributed to the naturally occurring presence of selenium in onsite soils. Whereas these Alternate Source Demonstrations were submitted to address particular exceedances at either North or South landfill, we suggest that all Alternate Source Demonstrations noted above are applicable to all waste management units at the facility. Such general applicability is demonstrated by the Alternate Source Demonstrations submitted separately for cobalt at both North and South waste management units. Future Actions. Based upon the results of the subject sampling event, the facility may continue monitoring groundwater in accordance with the current program.

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. Contact your Pace PM for the current list of accredited analytes. TNI - The NELAC Institute. ANALYTE QUALIFIERS Analysis conducted outside the EPA method holding time.H1 The recalculated concentration of the calibration standard(s) did not meet method acceptance criteria; this result should be considered an estimated value.IK Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.M1 The continuing calibration verification was below the method acceptance limit. The analyte was not detected in the associated samples and the sensitivity of the instrument was verified with a reporting limit check standard.v2 The continuing calibration verification was below the method acceptance limit. Any detection for the analyte in the associated samples may have low bias.v3 REPORT OF LABORATORY ANALYSIS This report shall not be reproduced, except in full, without the written consent of Pace Analytical Services, LLC.Date: 12/04/2023 07:54 PM Pace Analytical Services, LLC 9800 Kincey Ave. Suite 100 Huntersville, NC 28078 (704)875-9092 Page 22 of 27 #=CR# QUALITY CONTROL DATA CROSS REFERENCE TABLE Pace Project No.: Project: 92699898 OCSWM FALL-NORTH (MW-04) Lab ID Sample ID QC Batch Method QC Batch Analytical Method Analytical Batch 92699898001 815073 8151836801-MW04 EPA 3010A EPA 6010D 92699898001 815270 8152936801-MW04 EPA 7470A EPA 7470A 92699898001 8151756801-MW04 EPA 8260D 92699898002 815175TRIP BLANK EPA 8260D 92699898001 8152056801-MW04 EPA 8260D Mod. 92699898002 815205TRIP BLANK EPA 8260D Mod. 92699898001 8160236801-MW04 SM 2320B-2011 92699898001 8153976801-MW04 SM 2540C-2015 92699898001 8152506801-MW04 SM 4500-S2D-2011 92699898001 8149616801-MW04 EPA 300.0 Rev 2.1 1993 92699898001 8152976801-MW04 SM 3500-Cr B-2011 REPORT OF LABORATORY ANALYSIS This report shall not be reproduced, except in full, without the written consent of Pace Analytical Services, LLC.Date: 12/04/2023 07:54 PM Pace Analytical Services, LLC 9800 Kincey Ave. Suite 100 Huntersville, NC 28078 (704)875-9092 Page 23 of 27 Page 24 of 27 Page 25 of 27 Page 26 of 27 Page 27 of 27 #=CL# December 04, 2023 LIMS USE: FR - DEBORAH COAKLEY LIMS OBJECT ID: 92699907 92699907 Project: Pace Project No.: RE: Deborah Ann Coakley TRC Companies 1030 Wilmer Ave. Suite 100 Richmond, VA 23227 OCSWM FALL-SOUTH MW110D/MW110S Dear Deborah Coakley: Enclosed are the analytical results for sample(s) received by the laboratory on November 20, 2023.

Detailed sampling procedures are documented on a series of groundwater sampling forms (presented at the end of this ATTACHMENT). 1.1 Chronology On November 20, through November 22, 2023 (sampling event 59), TRC personnel obtained groundwater samples from groundwater monitoring wells associated with the Orange County Solid Waste Management South Facility (south side of Eubanks Road). During the subject sampling event, samples were obtained for the following chemical analyses: • Samples were obtained from upgradient monitoring well 6801-MW04 for analysis of [1] the constituents listed in 40 CFR Part 258 Appendix I (15A NCAC 13B .1600; plus 1,4- dioxane), [2] those constituents listed in Appendix II that have been previously and reliably detected at North landfill (mercury, naphthalene, sulfide) and [3] for those constituents required by regulations for monitoring of C&D landfills (manganese, iron, chloride, sulfate, total dissolved solids, alkalinity). Note. Well 6801-MW04 is associated with the monitoring programs for the closed North sanitary landfill, the closed South sanitary landfill, and the active C&D landfill. • Additional samples were obtained from upgradient monitoring well 6801-MW110S for quality control parameters. • Samples were obtained from upgradient monitoring well 6801-MW110S for analysis of [1] the constituents listed in Appendix I (plus 1,4-dioxane) and [2] the constituents required by regulations for monitoring of C&D landfills (manganese, iron, mercury, chloride, sulfate, tetrahydrofuran, total dissolved solids, alkalinity). Note. Well 6801-MW110S is associated with the monitoring programs for the closed North sanitary landfill, the South sanitary landfill, and active C&D landfill. • Additional samples were obtained from upgradient well 6801-MW110S for quality control parameters. • Samples were obtained from upgradient monitoring well 6801-MW110D for analysis of total arsenic.. • Samples obtained from six compliance wells (6801-MW101, 6801-MW102S, 6801-MW104, 6801-MW106, 6801-MW107, 6801-MW111) were analyzed for the constituents listed in Appendix I (plus 1,4-dioxane). • Samples obtained from one compliance well (6801-MW105) were analyzed for the constituents listed in Appendix I (plus 1,4-dioxane), semi-volatile organics, PCBs and pesticides. Groundwater Monitoring Program March 2024 Results of Sampling and Analysis Attachment 8 Sampling Event 59: 11.20.23 to 11.22.23 OCSWM South Facility, Permit No. 68-01 Page 2 • Samples were not obtained from the leachate collection system at the South Facility due to lack of leachate. Historically, leachate is collected for analysis of the constituents listed in Appendix I, plus BOD, COD, manganese, mercury, nitrate, sulfate, and phosphorus. • Four trip blanks were to be analyzed for quality control purposes. TRC personnel did not sample wells 6801-MW102DR, 6801-MW103D, 6801-MW103S, or 6801- MW112, because NCDEQ no longer requires these wells to be sampled on a regular schedule. However, if Groundwater Quality Standards are exceeded in particular wells, then the following wells will be sampled: • 6801-MW102DR – sampled only if a Groundwater Quality Standard is exceeded in well 6801-102S • 6801-MW103D – sampled only if a Groundwater Quality Standard is exceeded in well 6801-103S • 6801-MW103S – sampled only if a Groundwater Quality Standard is exceeded in well 6801-MW104 • 6801-MW112 – sampled only if a Groundwater Quality Standard is exceeded in well 6801-MW105. MW-105 exceeded its Groundwater Quality Standards for Arsenic and Cobalt in November 2023. As a result, 6801-MW112 will be sampled in May 2024. 1.2 Well Inspection Prior to sampling groundwater, TRC personnel assessed the overall condition of each groundwater monitoring well (including the surface completion). According to documentation provided by TRC personnel, all wells were observed to be in generally good condition. 1.3 Static Water Levels Using a graduated electronic water level indicator, field personnel measured static water levels in each well prior to purging. All measurements were recorded to the nearest 0.01 foot (relative to the top of the PVC well pipe). A history of static water elevations is presented in ATTACHMENT 3. 1.4 Purging All permitted wells were purged by TRC personnel using dedicated, submersible bladder pumps with an electric compressor that was driven by a battery and associated control unit. Wells were purged using a performance-based (“low-flow”) criteria presented in the document Guidelines for Groundwater, Soil, and Surface Water Sampling (NCDEQ - SWS; April 2008). Field purge and sample logs provided by TRC are presented at the end of this ATTACHMENT. Groundwater Monitoring Program March 2024 Results of Sampling and Analysis Attachment 8 Sampling Event 59: 11.20.23 to 11.22.23 OCSWM South Facility, Permit No. 68-01 Page 3 1.5 Groundwater Stability The performance-based purging method essentially involves purging groundwater from a monitoring well at a sufficient rate so as not to significantly disturb the water column. During the purging process, several water quality parameters (pH, specific conductance, water temperature, dissolved oxygen, turbidity, ORP) are periodically measured until successive readings are generally consistent (within 10%). Additional purging criteria are presented in the Guidelines document discussed above. During the subject sampling event, the monitoring wells were purged until several consistent field parameter readings were recorded. These parameters were measured to help ensure that representative groundwater samples were obtained. Groundwater samples were obtained immediately after the physical parameters had stabilized. Stability is defined in the Groundwater Monitoring Plan as a deviation of less than 10% for three consecutive readings. Readings recorded for each well are presented at the end of this ATTACHMENT. Note. When water levels are low in a well, or when the screened portion of the aquifer is characterized by low hydraulic conductivity, the well may be purged to dryness. In such cases, field personnel will allow time for groundwater levels to equilibrate and restart the sampling process from the point at which it was interrupted. If the well again purges to dryness, the technician will obtain samples as the well recharges. In such cases, the groundwater samples are deemed “representative” even if the usual stable readings cannot be obtained. 1.6 Well Sampling Groundwater samples were obtained using the dedicated pumps immediately after pH, specific conductance, and temperature had stabilized. Additional samples for laboratory QA/QC analyses were obtained from well 6801-MW110S, including a Matrix Spike and Matrix Spike Duplicate. . 1.7 Well Sampling Order On November 20, through November 22, 2023 (sampling event 59), TRC personnel sampled upgradient well(s) before sampling downgradient wells. Downgradient wells were sampled in the order indicated by the times shown on the associated field records. 1.8 Preservation At the laboratory, all sample containers were prepared with preservative by Pace if required by the method in SW-846. All samples were placed beneath ice in coolers immediately after the samples were obtained. Groundwater Monitoring Program March 2024 Results of Sampling and Analysis Attachment 8 Sampling Event 59: 11.20.23 to 11.22.23 OCSWM South Facility, Permit No. 68-01 Page 4 1.9 Sample Transport Immediately after the samples were obtained, they were placed beneath ice in insulated containers for transportation to the laboratory. Samples obtained on November 20 through November 22, 2023, were hand-delivered to Pace on the day they were collected. Upon arrival at the laboratory, all temperatures inside of the insulated containers were measured and found to lie within acceptable limits (< 4°C). All samples were placed in a refrigerator upon arrival and held at approximately 4°C until the time at which they were analyzed. Additional information concerning each monitoring well is presented at the end of this ATTACHMENT.

Subsequent groundwater data (including data obtained during this sampling event) were compared to the facility background values contained in the September 1996, report. While preparing the report for event 25, the facility background concentration (FBAC) of total arsenic was revised using data derived from upgradient well 6801-MW110D (sampling event 1 through event 25). Facility background values (denoted as “FBAC”) are shown on a series of tables summarizing the history of groundwater chemistry at the facility (ATTACHMENT 5 and ATTACHMENT 6). Comment. During 2007, NCDEQ promulgated Solid Waste Section Limits (SWSLs) for listed organic and inorganic constituents, and for most general chemistry parameters. The SWSL values were established in lieu of laboratory Practical Quantitation Limits (PQLs) and were intended to function as the laboratory reporting limits. Comment. During 2018, NCDEQ discontinued the use of SWSLs, and facilities were advised to choose EPA approved analytical methods sufficiently sensitive to quantify the presence of a pollutant at or below applicable standards.

Any non-dedicated equipment used to purge and sample monitoring wells was decontaminated before and after sampling each well. In addition, trip blanks were analyzed to help validate the observed concentrations of specific constituents. The concentration of each constituent observed in groundwater was compared to the concentration observed in each blank in accordance with the following rules: • Regarding common organic laboratory contaminants (acetone, 2-butanone, methylene chloride) and common phthalate contaminants, if the concentration in groundwater is less than ten times (10x) the concentration in the blank, then we conclude that the constituent in the groundwater sample may be attributed to cross-contamination. • Regarding organic contaminants that are not commonly used in the laboratory and inorganic contaminants in general, if the concentration in groundwater is less than five times (5x) the concentration in the blank, then we conclude that the constituent in the groundwater sample may be attributed to cross-contamination. 1.1 Deviations from the Plan All sampling techniques met the specifications set forth in the Groundwater Monitoring Plan. 1.2 Trip Blanks Trip blanks were prepared by the laboratory and transported by field personnel to each monitoring well location. Trip blanks remained in the insulated container, and the lids of the containers were never removed from the time the vehicle left the laboratory until the time field personnel delivered the samples to the laboratory. Trip blanks were analyzed for all constituents listed in 40 CFR Part 258 Appendix II (15A NCAC 13B .1600) that are typically analyzed using EPA Method 8260D. The laboratory did not detect any VOCs in the four trip blanks submitted. 2.0 LABORATORY QUALITY ASSURANCE / QUALITY CONTROL A limited QA/QC review was performed on the data provided by Pace Laboratories. In general, the Environmental Protection Agency's (EPA) Contract Laboratory Program (CLP) guidelines for data validation in Region III were followed; however, SW-846 control limits (latest promulgated edition) were used for QA/QC requirements. Groundwater Monitoring Program March 2024 Results of Sampling and Analysis Attachment 10 Sampling Event 59: 11.20.23 to 11.22.23 OCSWM South Facility, Permit No. 68-01 Specifically, laboratory blanks were analyzed to help validate the observed concentrations of specific constituents.
