The facility property is located on Rocky Ford Road, approximately six miles southwest of Newton, North Carolina. The approximate property boundary and disposal area are indicated on a portion of the USGS 71/2 minute topographic map for Reepsville, North Carolina (Figure 1). Four solid waste disposal units are maintained by Catawba County at this facility, as shown on Drawing 1, including: • Blackburn Landfill, Closed Portion (Unit 1): a closed, unlined, municipal solid waste (MSW) landfill area, located in the south-central portion of the facility property. • Blackburn Landfill, Subtitle D Facility (Units 2 and 3): an active, lined, MSW landfill on the south side of North Carolina Route 2019, contiguous to the north of Unit 1. • New construction and demolition (C & D) Landfill (C & D Unit 2): located to the south of the active Subtitle D disposal area and west of the Closed Unit 1. • Old C & D Landfill (C & D Unit 1), a closed C & D landfill located across Route 2019 to the north of the active Subtitle D disposal area. 1.2 Site Geology and Hydrogeology The Blackburn Resource Recovery Facility is located within the Inner Piedmont Belt of the Piedmont Physiographic Province. The bedrock of the Inner Piedmont Belt is characterized by medium to high grade metamorphic rocks ranging from marble to schist to gneiss, intruded by varying age plutons. A surface layer of saprolite over a transition zone of partially weathered bedrock, covers most of the area. In the Piedmont, the thickness of saprolite averages about 52 feet, and in some cases, may exceed depths of 100 feet (Daniel, 1990). The Inner Piedmont is bounded on the northwest by the Brevard Fault zone and on the southeast by the Kings Mountain Belt and faults and shear zones that define the central Piedmont structure. Rock units depicted on the North Carolina Geologic Survey - Geologic Map of North Carolina (1985) in the vicinity of the Blackburn Landfill Facility include interlayered; minor layers and lenses of hornblende gneiss, metagabbro, mica schist, and granitic rock of the Inner Piedmont, Chauga Belt, Smith River Allochthon, and Sauratown Mountain belts. Based on observations and data collection during previous subsurface exploration at the site, the site geology appears to be consistent with the regional mapping described on the Geologic Map of North Carolina, and rock cores were all described as biotite gneiss with localized granite masses. No outcrop was encountered on the site (CDM-Smith, 2018). Groundwater flow at the facility, as is typical for the Inner Piedmont Belt, is primarily within the saprolite and the partially weathered bedrock (transition zone); however, some flow also occurs along major fractures within the competent bedrock. The uppermost aquifer includes all three zones. The water table typically reflects topography, and groundwater flows from the higher topography (recharge areas) to the valleys where it discharges to perennial creeks, which flow to the South Fork of the Catawba River, located east of the facility. The South Fork of the Catawba River is classified WS-V, for waters protected as water supplies which are generally upstream and draining to Class WS-IV waters or waters used by industry to supply their employees with drinking water or as waters formerly used as water supply. These waters are also protected for Class C uses. March 2022 Water Quality Monitoring Report LaBella Associates Catawba County Blackburn Landfill, Permit No. 18-03 July 2022 1 1.3 Regulatory Status Catawba County completes water quality monitoring at the Blackburn Landfill in accordance with the North Carolina Solid Waste Management Regulations (NCSWMR - 15A NCAC 13B) § 1633 (Detection Monitoring Program) for all units except the Closed MSW Unit 1. MSW Unit 1 is monitored under an Assessment Monitoring program, as described under NCSWMR § 1634. In February 2019, NCDEQ approved a reduction in the required Assessment Monitoring requirements, eliminating the requirement for annual NC Appendix II sampling. Surface water at the facility is monitored semiannually in accordance with NCSWMR § 0602 in conjunction with the groundwater monitoring events. The facility's leachate is also sampled during each semiannual event. The facility currently monitors groundwater and surface water for the constituents listed in 40 CFR Part 258 Appendix I, incorporated by reference into the NCSWMR (NC Appendix 1), plus 1,4-dioxane for all of the MSW units. The C&D Units are monitored for NC Appendix I VOCs, 8 RCRA metals, tetrahydrofuran (THF), and 1,4-dioxane. 2.0 FACILITY MONITORING PROGRAM 2.1 Groundwater Monitoring Program Water quality monitoring is conducted semiannually at the facility, typically in March and September. Well MW-20 serves as the upgradient background monitoring well for MSW Unit 1, MSW Unit 2, MSW Unit 3, and C&D Unit 1. MW-21 serves as the background well for C&D Unit 2. The Unit 1 compliance monitoring network includes wells MW-5, MW-5A, MW-6, MW-6D, MW-7, and MW-11. Two piezometers, PZ-85B and PZ-86B, located along the eastern side of Unit 1, are included in the network in order to monitor impacts of landfill gas from the closed area to groundwater in the vicinity. The Unit 2 monitoring network includes wells MW-12R, MW-13, MW-14, MW-15, MW-16, and MW- 17. Well MW-12 was replaced with MW-12R prior to the second semiannual 2019 event due to damage to the inner well casing of MW-12 that prevented purging of the well. The Unit 3 monitoring network includes wells MW-31R, MW-32, MW-33R, MW-35, and MW-36. Well MW-34 was removed in preparation for construction of expansion cell Unit 3, Phase 2. Well MW-33 was damaged by a vehicle and had to be repaired prior to the second semiannual event of 2020, which changed the elevation of the top of casing, and the well was renamed MW-33R. The C&D Unit 1 monitoring system includes wells MW-2, MW-26, and MW-27. The C&D Unit 2 compliance wells include MW-24, MW-25, MW-28, MW- 29, and MW-30. In addition to the above groundwater sampling points, several wells across the site are used only for water level monitoring. The following table summarizes the groundwater monitoring network and shows the analytical parameters currently required for each well. The locations of the monitoring wells are shown on Drawing 1 and the well construction data are included in Appendix 1.

SMP-1 and SMP- 3 are located on the intermittent creek that runs along the west side of MSW Units 1 and 2 and the east side of C&D Unit 2. SMP-3 is the upstream location and SMP-1 is downstream. U-1, U-2, and U-3 are located at the base of the western slope of MSW Unit 2, upgradient of SMP-3. SMP-4 is located on an intermittent creek downstream from the sedimentation basin east of MSW Unit 3. SMP-5 is located on an intermittent creek east of MSW Unit 1. The locations of these sampling points are shown on Drawing 1. Surface water at the facility is sampled semiannually in conjunction with the groundwater monitoring events. All surface water samples are analyzed for NC Appendix I parameters and 1,4-dioxane. March 2022 Water Quality Monitoring Report LaBella Associates Catawba County Blackburn Landfill, Permit No. 18-03 July 2022 3 The surface water at the facility flows offsite to the South Fork of the Catawba River, located east of the facility. The South Fork of the Catawba River is classified WS-V, which are waters protected as water supplies which are generally upstream and draining to Class WS-IV waters, or waters used by industry to supply their employees with drinking water, or as waters formerly used as water supply. 2.3 Leachate Monitoring Program The facility's leachate is also sampled during each semiannual event. Leachate is sampled directly from the facility's leachate collection system, shown on Drawing 1. The leachate sample is analyzed for NC Appendix I parameters, COD, BOD, nitrate, sulfate, and orthophosphate. 3.0 March 2022 SAMPLING EVENT 3.1 Field Work 3.1.1 Groundwater Monitoring On March 22-24, 2022, personnel from Labella Associates, visited Blackburn Landfill to conduct the first semiannual sampling event of 2022 (March 2022 Sampling Event). The sampling event included obtaining water levels to the nearest 0.01 foot, purging the wells, and collecting groundwater samples from twenty-nine monitoring wells, included all of the wells described in Section 2.1 above. The water level data and calculated groundwater elevations are presented in Table 1. Monitoring wells were purged and sampled using either disposable bailers or a 12-volt submersible pump. Measurements of temperature, pH, specific conductivity, dissolved oxygen, oxidation reduction potential, and turbidity were recorded prior to purging, after each purge volume, and prior to sampling. Copies of the field data logs are presented in Appendix 2 and the field parameters are summarized in Table 2. Prior to sampling, laboratory -supplied containers were prepared with the following information: • Monitoring well number (completed by laboratory/field personnel); • Date and time of sample collection (completed by laboratory/field personnel); • Initials of sampling personnel (completed by laboratory/field personnel); • Project name and number (completed by the laboratory/field personnel); • Chemical preservative (completed by the laboratory/field personnel); and • Requested chemical analysis (completed by the laboratory/field personnel). Groundwater samples from each monitoring well were collected directly from the bailers or pump in the laboratory -provided containers within 24 hours of the final purge volume. Immediately after collection, the samples were placed in a laboratory -provided cooler and chilled on ice for transport to the laboratory. In addition to samples for total metals analyses (whether Appendix I metals or RCRA metals), filtered samples for dissolved metals analyses were obtained from some wells which exhibited high turbidity. These samples were sent to the laboratory with instructions to hold them and not run the dissolved metals analyses until after the results for the total metals analyses were available. March 2022 Water Quality Monitoring Report LaBella Associates Catawba County Blackburn Landfill, Permit No. 18-03 July 2022 4 3.1.2 Surface Water Monitoring During the March 2022 Sampling Event, surface water points SW-3, SW-4, and SW-5 were sampled. Surface water point SW-1, and underdrains U-1, U-2, and U-3 were either dry or had no flow and could not be sampled. The surface water samples were collected by submerging a clean, unpreserved sample jar into the stream flow, being careful to avoid sampling -induced turbidity, and then dispensing the sample into the laboratory -prepared containers. The samples were then placed in a cooler and chilled on ice. Copies of the field data logs are presented in Appendix 2 and the field parameters are summarized in Table 2. 3.1.3 Leachate Monitoring Leachate samples were collected from the leachate sampling port on the back of leachate tank #2 during the March 2022 Sampling Event. Prepared sampling containers were filled directly from the port, placed in a cooler, and chilled on ice. At the time of sampling, leachate was measured for temperature, pH, specific conductivity, dissolved oxygen, oxidation reduction potential, and turbidity. Copies of the field data logs are presented in Appendix 2 and the field parameters are summarized in Table 2. 3.1.4 Blanks In addition to samples collected for compliance monitoring at the Blackburn Landfill, a Trip Blank that was prepared by the laboratory accompanied the volatile sampling containers to and from the laboratory. The Trip Blank was analyzed for NC Appendix I volatile organics plus THE and 1,4- dioxane. A Field Blank was not collected by LaBella personnel as part of the March 2022 Sampling Event due to a laboratory error. 3.2 Laboratory Analysis and Quality Control The groundwater, surface water, and leachate samples collected during the March 2022 Sampling Event were submitted to ENCO Laboratories, Inc. of Cary, North Carolina under chain -of -custody control for analysis. LaBella requested a Level II data report for the final laboratory reports. According to the laboratory reports, the samples were received by the laboratory on March 25, 2022, in good condition, properly preserved, at the required temperature, and within the hold times for each analytical method. The complete laboratory analytical data packages and chains of custody are included in Appendix 3. Upon receipt of the laboratory data packages, the data was reviewed by LaBella personnel for the following: • General typographical errors; • Correct analyses performed and within method specified hold times; • Biased data results based on Matrix Spike, Matrix Spike Duplicate, and Laboratory Control Samples; • Blank qualified data (B-flags); and • Groundwater detections above the 15A NCAC 2L.0202 (NC2L) Groundwater Standards. • Surface water detections above the 15A NCAC 2B (NC2B) Surface Water Standards, the NC In -Stream Target Values (ISTV), or the EPA National Recommended Water Quality Criteria (NRWQC). March 2022 Water Quality Monitoring Report LaBella Associates Catawba County Blackburn Landfill, Permit No. 18-03 July 2022 5 After initial review of the total metals analytical results, LaBella requested that ENCO run the dissolved metals analyses for barium in MW-27, cobalt in MW-6, MW-7, and MW-11, and chromium in MW-6, MW-24, and MW-29. These were the metals detected in exceedance of the NC21- standards in the total metals analyses. 4.0 HYDROGEOLOGICAL CONDITIONS Depth to groundwater was measured in the compliance monitoring wells at the site prior to purging. The groundwater elevations were calculated by subtracting the depth to groundwater from the surveyed measuring point elevation (top of casing) at each monitoring well. Groundwater elevations from the March 2022 Sampling Event are presented in Table 1. The groundwater elevation contours shown on Drawing 1 are based on data from the March 2022 Sampling Event The estimated horizontal groundwater gradients along the flow paths shown on Drawing 1 were calculated using the data from the March 2022 Sampling Event are presented in Table 3. The estimated horizontal groundwater gradients (i) range from 0.025 to 0.052 with an average horizontal gradient of 0.034. Hydraulic conductivities (K) and effective porosities (ne) were taken from the First Semiannual 2021 Groundwater Monitoring Report for the facility (Pace, March 2022), with the assumption that these values were derived from slug tests and porosity tests, respectively, from the facility monitoring wells; however, the specific source for these values was not cited. A hydraulic conductivity of K = 7.7 x 10-4 cm/sec was used for MSW Units 2 and 3. A hydraulic conductivity of K = 1.9 x 10-3 cm/sec was used for MSW Unit 1 and C&D Units 1 and 2. An effective porosity of 21% (ne = 0.21) was used for the whole facility. Linear groundwater flow velocities for wells screened in saprolite were computed using the following modified Darcy equation: where: V = KI/ne, V = average linear velocity (feet per day - ft/day); K = hydraulic conductivity (ft/day); i = horizontal hydraulic gradient; and ne = effective porosity. Based on calculations from the March 2022 Sampling Event, the estimated linear groundwater flow velocity for the site ranges from 97 feet/year to 486 feet/year with an average of 281 feet/year (Table 3). This falls within the range of historical estimates for groundwater flow velocities at this site. The linear velocity equation and resulting rates are based on simplified assumptions of a homogeneous, isotropic, porous aquifer. This equation may yield inaccurate velocities when applied to heterogeneous and/or anisotropic conditions such as may exist at this site. The regolith and fractured bedrock common in Piedmont terrain are characteristically heterogeneous and often exhibit some anisotropy. March 2022 Water Quality Monitoring Report LaBella Associates Catawba County Blackburn Landfill, Permit No. 18-03 July 2022 6 5,0 DATA ANALYSIS The complete analytical data packages from the March 2022 Sampling Event were received from ENCO Laboratories, Inc., on April 12, 2022. The complete data packages and chains of custody are included in Appendix 3. 5.1 Analytical Results for Groundwater and Comparison to Standards Analytical results from groundwater samples were compared directly to applicable groundwater protection standards (GPS), which are the North Carolina Groundwater Standards found in 15A NCAC 02L.0202 (NC2L Standards). Note that estimated concentrations below the Method Reporting Limit (MRL) are not considered exceedances of the standard, even if the estimated value is higher than the standard.

Of the quantified detections in the C&D monitoring wells, the following constituents were detected in exceedance of their respective GPS (see Table 5): • 1,4-dioxane (MW-2, MW-24, MW-25, MW-28); • Barium (MW-27); • Benzene (MW-24, MW-25); • Chromium (MW-24, MW-29); and • Tetrahydrofuran (MW-24, MW-25). 5.1.4 Dissolved Metals Field -filtered samples were collected for dissolved metals analyses for all wells in the field. The laboratory was instructed to hold these samples pending the results of the total metals analyses. Upon review of the total metals results, the laboratory was instructed to run dissolved metals analyses for barium in MW-27; chromium in MW-6, MW-24, and MW-29; and cobalt in MW-6, MW-7, and MW-11. The results of the dissolved metals analyses are presented in Table 6, and the complete laboratory analytical reports are included in Appendix 3. Chromium in MW-29, cobalt in MW-11, and barium in MW-27 presence came back higher in the dissolved metal samples than in the total metals samples. All other dissolved metal samples showed a decrease in concentrations compared to their total metal counterparts; however, only dissolved chromium in MW-6 and MW-24 were below the NC21L Standard. 5.3 Analytical Results for Surface Water and Comparison to Standards Analytical results from surface water samples were compared directly to applicable surface water standards, which are either the North Carolina Surface Water Standards found in 15A NCAC 02B (NC2B Standards), the NCDEQ Instream Target Values (ISTVs) for constituents with no listed NC2B Standard, or the US -EPA National Recommended Water Quality Criteria (NRWQC) for constituents with no listed NC2B Standard or ISTV. Surface water standards for a given constituent vary depending on the classification of the water body. The surface water at the facility flows offsite to the South Fork of the Catawba River, which is March 2022 Water Quality Monitoring Report LaBella Associates Catawba County Blackburn Landfill, Permit No. 18-03 July 2022 8 classified WS-V, for waters protected as water supplies which are upstream of Class WS-IV waters, used by industry to supply their employees with drinking water, or waters formerly used as water supply. Therefore, the standards applied to the results for this facility were the standards for fresh water supplies or freshwater fish consumption, whichever was lower. In addition, for some constituents, there are standards for both acute and chronic exposure; in which case the lower of the two standards was used. For several metals, the NC213 standards are dependent on hardness; therefore, all surface water samples were analyzed for hardness in addition to the required analyses, and the standards were calculated based on the hardness for each sample. Table 4D summarizes the constituents detected in all surface water samples during the March 2022 sampling event, and constituents detected in exceedance of their respective standards are included in Table 5. Note that estimated concentrations below the Method Reporting Limit (MRL) are not considered exceedances of the standard, even if the estimated value is higher than the standard. The only inorganic constituent detected at quantified concentrations above the MRL in surface water samples was barium (all samples). There were no organic constituents detected at quantified concentrations above the MRL in surface water samples. No constituents were detected in exceedance of their respective surface water standards during the March 2022 Sampling Event. 5.4 Leachate Data Analyses Concentrations of constituents and parameters reported for the leachate sample collected during the March 2022 sampling event are summarized in Table 7. The leachate results are consistent with historical data. The complete laboratory analytical report for leachate is included in Appendix 3. 5.5 Statistical Analyses No statistical Analyses were performed for this report. 6.0 CONCLUSIONS The groundwater analytical results for all units at the Blackburn Landfill from the March 2022 Sampling Event are generally consistent with historical data. There were numerous GPS exceedances across the site as a whole. We recommend that the Blackburn Landfill MSW Unit 1 remain in modified Assessment Monitoring and that the rest of the facility remain in the Detection Monitoring program. The next semiannual sampling event is tentatively scheduled for September 2022. 7.0 REFERENCES Brown, Philip M., Chief Geologist, 1985, Geologic Map of North Carolina, The North Carolina Geologic Survey, scale 1:500,000.
