The Old Hickory Landfill (Site) is located in the City of Hickory, west of 4th Street Drive SW and between US Highway 70 and 7th Avenue SW. The Site, defined by the Inactive Hazardous Sites Program as “any area where a hazardous substance or waste has been deposited, stored, disposed of, placed, or otherwise come to be located”, is located on 16 adjacent parcels, roughly bounded by US Highway 70 to the south to 7th Avenue SW to the north, and from 6th Street Drive SW to the west to 4th Street Drive SW to the east. The 16 parcels comprising the WDA are zoned C-3 (Regional Commercial) by the City of Hickory. According to delineation efforts, the Waste Disposal Area (WDA) comprises approximately 11.62 acres. The WDA is generally improved upon with commercial development, including a number of businesses, a motel, parking lots, streets, and a miniature golf course. The westernmost limits of the WDA (adjacent to an unnamed tributary of Geitner Branch) are covered by wooded land. There is no documentation of surface waste observed at the Site. According to information presented in readily-available historical documents, the precise dates of time the Site operated as a landfill are unknown. However, it is believed that dumping operations ended in the early to mid-1950s. Residential development is generally present to the north and northwest of the Site beyond 7th Avenue SW and 6th Street Drive SW. Commercial development is generally located beyond 4th Street Drive SW and along US Highway 70 to the east, south and west of the Site. The Site is accessed via these roads and by various public roads that extend through the Site. Figure 1 illustrates the Site property boundaries on the Vicinity Map. Figure 2 illustrates the Waste Disposal Area on the Investigation Location Map. 2.0 SENSITIVE ENVIRONMENTS Sensitive environments have not been identified within the Site vicinity. 3.0 GEOPHYSICAL SURVEY A geophysical survey was performed in December 2011 to obtain preliminary information on the horizontal extents of the WDA. A ground penetrating radar (GPR) unit was utilized, which identified a presumed waste disposal area along much of the western and nearly the entire southern border of the Site. This area of suspected waste appeared to extend beyond 6th Street Drive to the west and Task Order 794SUM-B PRLF ID #NONCD0000794 Old Hickory Landfill, Hickory, NC January 28, 2021 Page 2 of 11 approximately mid-way across US Highway 70 to the south. The WDA was further delineated via auger drilling methods as described in Section 6.0. The geophysical survey also identified two smaller areas of suspected waste, which were later determined by drilling methods to not contain waste. The limits of the WDA as determined by geophysical survey and drilling methods are depicted in Figure 3. 4.0 SITE GEOLOGY AND HYDROGEOLOGY Catawba County, North Carolina, is located within the Inner Piedmont Physiographic Province. The surface elevation at the Site ranges from approximately 1,040 to 1,100 feet above Mean Sea Level. Topography within the disposal area is generally sloped to the west. Surface soils on the Site are classified primarily as micaceous sandy silts. The soils lie on top of decomposed rock (saprolite). The 1985 Geologic Map of North Carolina maps bedrock in the vicinity of the Site as mica schist on the north side and biotite gneiss and schist on the south side of the Site. Within the study area, groundwater occurs primarily within an unconfined aquifer composed of fractured metamorphic bedrock overlain by saprolite. Groundwater has been encountered approximately 19 to 27 feet below ground surface (BGS), where elevation data indicate a west to northwest groundwater flow direction. According to information presented in A Geochemical Atlas of North Carolina, NURE Database and Geochemical Applications for State Government, elevated levels of inorganics were evident in soils located near western Catawba County (using the data mapped nearest to Hickory NC, in Iredell and Caldwell Counties). Soil detections included: •Arsenic (0.6 – 4.5 ppm): •Iron (22,800 – 74,900 ppm); •Manganese (149 – 916 ppm); •Thallium (0.3 – 0.4 ppm). Therefore, relatively high, naturally-occurring concentrations of these metals are anticipated at the Site and surrounding vicinity. 5.0 NATURAL BACKGROUND Background soil, sediment and surface water samples were collected near the Site in May 2019 and submitted for laboratory analysis. These analytical results were evaluated to establish natural metals concentrations and area-wide anthropogenic background levels. Task Order 794SUM-B PRLF ID #NONCD0000794 Old Hickory Landfill, Hickory, NC January 28, 2021 Page 3 of 11 Four soil borings were advanced near the Site to a depth of 18 feet BGS. Three soil samples were collected from each background soil boring. Several metals were detected in the soil samples at levels exceeding Preliminary Soil Remediation Goals (PSRGs), including arsenic, iron, manganese, and thallium. Two surface water samples were collected from the adjacent unnamed tributary at locations upgradient of the WDA. Three metals were detected in the surface water samples, including iron, manganese, and zinc. The concentrations of manganese and zinc exceeded their respective 15A NCAC 02B Surface Water Quality (2B) Standards. No 2B Standard currently exists for iron. Sediment samples were collected from the same locations where surface water samples were collected. Arsenic was detected in each sample at a concentration above its Residential PSRG, and iron was detected above the Residential PSRG in sample SW-2. Soil, surface water and sediment sample locations are depicted on the attached Figure 2, Investigation Location Map. Background soil and sediment sample laboratory data are summarized in the attached Table 1A, and surface water laboratory data are summarized in the attached Table 1B. Sediment and background soil samples that exceeded Residential PSRGs are depicted on Figure 4A. Surface water samples that exceeded 2B Standards are depicted on Figure 4B. 6.0 WASTE DISPOSAL AREA Soil borings were advanced along the perimeter of the WDA to further delineate the extent of the waste identified by the geophysical survey. Borings were advanced at approximately 53 locations via auger drilling methods to visually identify the presence or absence of waste. Where waste was not encountered in a soil boring (to a depth of 10 feet), offset borings were advanced toward the suspected WDA until waste was encountered in a soil boring. Similarly, where waste was encountered in a soil boring, offset borings were advanced away from the suspected WDA limits until waste was not encountered in a soil boring. GPS coordinates were collected at these boring locations. Based on the resulting data, the extent of the WDA was redefined as shown on Figure 2, which comprises approximately 8.47 acres. Figure 3 illustrates the waste disposal area based on historical investigations and data. Table 2 presents WDA perimeter delineation boring information. Task Order 794SUM-B PRLF ID #NONCD0000794 Old Hickory Landfill, Hickory, NC January 28, 2021 Page 4 of 11 7.0 MEDIA CHARACTERIZATION 7.1 Above Ground Vapor Survey Ambient air readings were collected in 2012, 2013, and 2014 at the locations of the landfill gas probes detailed in Section 7.7. Ambient air measurements for methane, oxygen, carbon dioxide, hydrogen sulfide, and volatile organic compounds (VOCs) were recorded. Readings indicative of landfill gas vapors were not detected during these events. 7.2 Waste Characterization Soil borings were advanced within the WDA at 26 locations to collect information on the depth and characteristics of the waste throughout the Site. Debris typical of municipal solid waste was observed within the borings, including metal, wood, glass, plastic, cloth, and rubber. Wastes were observed to range in thickness from 0.5 to 28 feet. The average waste thickness was calculated to be 9.52 feet. Using an average waste thickness of 9.52 feet across the 8.47-acre WDA, the waste volume is estimated to be approximately 130,090 cubic yards. Each waste characterization boring was continuously logged, and up to three solid media samples were collected from each boring: (1) above the waste, (2) within the waste media, and (3) below the waste. Soil/waste samples were submitted for laboratory analysis of the following parameters by the most current U.S. EPA Contract Laboratory Program Target Compound List, including: •Volatile organic compounds (VOCs); •1,4-dioxane; •Semi-volatile organic compounds (SVOCs); •HSL Metals; and •Ammonia; nitrate; and sulfate. Samples were also analyzed for the Top 10 tentatively identified compounds (TICs). Hexavalent chromium was analyzed on the four soil samples that contained the highest concentrations of total chromium. Waste characterization borings are depicted on Figure 2, and detailed waste characterization boring information is presented in Table 3. 7.3 Soil Cover Historically, soils were placed to cover the waste at the Site. The cover soils across the WDA were observed to vary, ranging in total depth from approximately 1 foot to 8 feet BGS on the eastern end of the WDA; from approximately 4.5 feet to 10 feet BGS in the central portion of the WDA; and Task Order 794SUM-B PRLF ID #NONCD0000794 Old Hickory Landfill, Hickory, NC January 28, 2021 Page 5 of 11 from approximately 3 feet to 10 feet BGS on the western end of the WDA. Cover soil was observed up to approximately 26 feet deep in the westernmost waste characterization boring, located west of 6th Street Drive SW). Cover soil thicknesses are summarized in Table 3, and a generalized Cover Soil Thickness Map is included as Figure 5. 7.4 Surface Water/Sediment/Seep Investigation Surface Water Investigation Surface water samples were collected from the unnamed tributary located adjacent and to the west of the WDA. Samples were collected in 2012 and 2019 and were submitted for laboratory analysis of VOCs; SVOCs; 15 metals including mercury; ammonia, nitrate, and sulfate. The 2019 surface water samples were also submitted for analysis of 1,4-dioxane, as well as hexavalent chromium on the sample with the highest concentration of total chromium. Inorganic analytes detected in the 2012 surface water samples included elevated manganese in the downstream (SW-1) sample at a concentration above the 2B Standard. Elevated levels of manganese and zinc were detected in the three 2019 surface water samples at concentrations above the 2B Standards. Concentrations of manganese in both sampling events were higher in the most downstream sample location (SW-1). Other metals were detected at similar concentrations in the upstream and downstream sample locations. Analytical results for surface water samples are summarized in Table 1B. Surface water samples that exceeded the 2B Standards are depicted on Figure 4B. Sediment Investigation Sediment samples were collected from the unnamed tributary at the surface water sample locations. Samples were collected in 2012 and 2019 and were submitted for analysis of the same parameters described above in the Surface Water Investigation section. Several SVOCs were detected at concentrations exceeding PSRG levels in the 2012 samples; however, no SVOCs were detected in the 2019 sediment samples. Arsenic was detected in each sample collected in 2019 at concentrations above the Residential PSRG. Iron was detected at a concentration just above the Residential PSRG in sample SW-2 in 2019. Sediment sample laboratory data are summarized in Table 1A. Sediment and background soil samples that exceeded Residential PSRGs are depicted on Figure 4A. Seep Investigation Seeps have not been observed on the Site. Task Order 794SUM-B PRLF ID #NONCD0000794 Old Hickory Landfill, Hickory, NC January 28, 2021 Page 6 of 11 7.5 Groundwater Investigation Six Type III flush-mounted permanent groundwater monitoring wells were constructed within the landfill waste boundary in 2013. The monitoring wells were initially drilled to a depth below the extent of waste, or until bedrock was encountered. Six-inch diameter casings were installed to isolate the waste interval. Each well was then advanced through the casing until groundwater was encountered, and then completed with a 10-foot screened interval. Table 4, Monitoring Well Construction Information summarizes locations, depths, elevations, and well construction details. Groundwater samples were collected from the monitoring wells in 2013 and 2019, and were analyzed for VOCs, 1,4-dioxane, SVOCs, total metals, ammonia, nitrate, and sulfate. The three groundwater samples with the highest total chromium concentrations collected in 2019 were also analyzed for hexavalent chromium. Exceedances of several inorganic analytes were detected above 15A NCAC 02L Groundwater Quality (2L) Standards during both sampling events, including chromium, iron, manganese, and nickel. Table 5 summarizes groundwater analytical data collected at the Site, and Figure 6, Groundwater Analytical Data, depicts sample locations and analytical results that exceeded 2L Standards. As groundwater flows through on-site soils, high levels of naturally-occurring iron and manganese (noted in Section 4.0 above) dissolve and, accordingly, resulted in high concentrations of iron and manganese detected in groundwater samples (The USGS Water Science School, 2016). The depth to groundwater on site ranges from approximately 19 feet to 27 feet BGS. Previous groundwater data collected on site have indicated groundwater flows west to northwest toward the unnamed tributary of Geitner Branch. 7.6 Potable Water Supply Well Sampling Potable water supply wells were not observed on the Site or within 1,000 feet of the Site. City of Hickory provides water to the Site and surrounding area. 7.7 Landfill Gas Probe Installation and Monitoring Landfill gas was evaluated from 19 landfill gas probes (GP-1 through GP-19) that were installed in 2012, 2013, and 2014, and again in 2019. Field activities consisted of screening each probe for oxygen, carbon dioxide, methane, total VOCs, and hydrogen sulfide. Task Order 794SUM-B PRLF ID #NONCD0000794 Old Hickory Landfill, Hickory, NC January 28, 2021 Page 7 of 11 Methane has historically been detected at the Site, with the highest concentrations recorded in landfill gas probes GP-4 (up to 46.1% methane by volume), GP-5 (up to 77.7% by volume) and GP-6 (up to 48.3% by volume). Concentrations of methane between the lower and upper explosive limits have consistently been detected in landfill gas probes GP-2, GP-3, GP-9, GP-10, GP-11, and GP-15. Hydrogen sulfide has also frequently been detected in nine landfill gas probes (GP-2 through GP-6, GP-9 through GP-11, and GP-15), ranging from 1 to 19 parts per million. The highest hydrogen sulfide readings have typically been observed in landfill gas probes GP-3 and GP-6. Historical landfill gas readings are summarized in Table 6, and depicted on Figure 7. In May 2013 and November 2014, landfill gas samples were collected in summa canisters and submitted to a certified laboratory for analysis of VOCs by EPA Method TO-15. Several VOCs were reported in 2013, including benzene, chlorobenzene, 1,4- dichlorobenzene, and dichlorodifluoromethane (Freon 12), reported at concentrations that exceeded the NCDEQ Inactive Hazardous Sites Branch Residential Vapor Intrusion Screening Levels (VISLs). In 2014, several VOCs were reported at concentrations that exceeded the Residential VISLs, including benzene; 1,4-dichlorobenzene; 1,2,4-trimethylbenzene; and 1,3,5- trimethylbenzene. No constituents were detected at concentrations that exceeded Non-Residential VISLs. Table 7, Landfill Gas Analytical Results, summarizes VOC laboratory results for the Site. Detections of VOCs above Residential VISL are shown on Figure 8, Landfill Gas Analytical Results. 7.8 Structural Vapor Intrusion Potential Indoor landfill gas surveys were conducted in various structures on and near the Site in December 2008, May 2012, and December 2015. Methane was detected in seven structures up to 0.5% by volume during the initial survey in 2008; hydrogen sulfide was not detected in any structures. Based upon the methane measurements recorded during this survey, methane alarms were either installed at or provided to 30 properties in the vicinity of the Site. Methane was not detected during the 2012 or 2015 surveys. Methane alarms were replaced in 11 structures in December 2015. 7.9 Contaminant Sources and Impacted Receptors No other sources have been identified that may be contributing to the potential and/or documented contamination at the Site.

Based upon the calculator, direct contact soil cumulative risk was exceeded for Resident, Construction Worker, and Recreator/Trespasser receptor categories. Cumulative vapor intrusion risk (indoor air and soil gas-to-indoor air) was exceeded for the Resident receptor category; and cumulative contaminant migration risk was exceeded for the groundwater pathway. In addition, the Total Sitewide Risk hazard indices were exceeded for the Non-Residential Worker in Current and Future Scenarios.
