Pleasant Maintenance Yard I rerracon September 25, 2019 Terracon Project No. 71177023 1.0 INTRODUCTION Terracon has prepared this Groundwater Monitoring Report on behalf of the North Carolina Department of Transportation (NCDOT) Roadside Environmental Unit. It presents the findings of recent field activities conducted by Terracon at the Mt. Pleasant Maintenance Facility (the site), located at 150 Dutch Road in Mt. Pleasant, Cabarrus County, North Carolina (Figure 1). 1.1 Site Description The site is located at 150 Dutch Road approximately 650 feet north of its intersection with NC Highway 73 in Mt. Pleasant, Cabarrus County, North Carolina. The site is bisected by Dutch Road. Topography at the site slopes gently to the west towards Dutch Buffalo Creek, which is located along the western property boundary. The site is currently occupied by the NCDOT Cabarrus County Maintenance Yard. The site is primarily asphalt -paved with isolated lawn and landscaped areas. Several buildings are located on the site including various administrative offices, maintenance shops, and storage buildings. Various NCDOT machinery, vehicles, and equipment are also staged on the site. The surrounding area is primarily used for agricultural and rural residential purposes. The Cabarrus Correction Center is located south of the site. 1.2 Site Operational History The site is currently occupied by the NCDOT Mt. Pleasant Maintenance Yard. Dating back to 1958, 12 underground petroleum storage tanks (USTs) have been maintained at the site. The USTs have contained gasoline, diesel, kerosene, or waste oil. Nine (9) of the USTs have been removed from the site, while three (3) remain in -place and are currently active. The following table provide details on the current and former on -site USTs. UST ID Size (gallons) Contents Date Installed Date Removed 1 3,000 Waste oil 09/26/1969 02/14/1990 2 2I5 Kerosene 09/29/1958 02/14/1990 3 2,000 Kerosene 09/29/1958 02/14/1990 4 2,000 Gasoline 09/29/1958 02/14/1990 5 6,000 Gasoline 08/30/1970 02/23/1990 6 10,000 Gasoline 1972? 03/28/1991 7 10,000 Gasoline 08/29/1972 03/28/1991 8 10,000 Diesel 08/29/1973 03/28/1991 9 2,000 Waste oil October 1989 05/31/2005 10 10,000 Gasoline 02/14/1990 Currently in use 11 10,000 Diesel 02/14/1990 Currently in use 12 1 2,000 Waste oil 02/14/1990 Currently in use Responsive ■ Resourceful ■ Reliable Groundwater Monitoring Report Irerracon NCDOT Mt. Pleasant Maintenance Yard September 25, 2019 Terracon Project No. 71177023 1.3 Site Investigation History The site was first investigated in May 1992 when three (3) monitoring wells were installed following the removal of USTs 1 through 8 in 1990 and 1991. Additional data regarding the identification, location, or analytical results associated with these wells was not available in the NCDEQ incident file associated with the site. Thirteen (13) monitoring wells (MW-1 through MW-10 and TP-1 through TP-3) were reported to have been located at the site (ECS, 1997). Groundwater has been estimated to flow to the north. Petroleum constituent concentrations are known to have historically been identified in monitoring wells MW-2, MW-4, MW-6, MW-7, MW-8, and MW-9. Free product was historically measured in monitoring well MW-6 (1.5 inches on November 14, 1996 [ECS, 1997]). Naphthalene was detected at a concentration of 197 micrograms per liter (ug/L) during the November 22, 1996 sampling event (ECS, 1997). Residual soil contamination has been reported in the vicinity of USTs 1 and 5 (ECS, 1997). The most recent investigation occurred in 2005 after the removal of UST 9 (2,000-gallon waste oil UST). 1.4 Historical Receptor Information Subsurface utilities consisting of water, sewer, and storm drain lines are present at the site generally buried at depths up to 3 feet below land surface (bls). Existing on -site buildings are constructed as slab -on -grade; thus, crawlspaces are not present. The closest surface water feature is Dutch Buffalo Creek, which extends along the western property boundary. Seven (7) water supply wells were previously identified within 1,500 feet of the source area (ECS, 1997). Public water is available to the site and surrounding properties by the Town of Mt. Pleasant. 1.5 Site Remedial History Remedial activities at the site have been limited to the removal of USTs and over -excavation of soils near the USTs. USTs 1 through 8 were removed in 1990 and 1991. Approximately 185 cubic yards of soil was reportedly removed and spread on the site with NCDEQ approval. The location of the spread soils is unknown. UST 9 was removed in 2005. Excavated soils were not reported during the removal of UST 9. E Responsive ■ Resourceful ■ Reliable Groundwater Monitoring Report NCDOT Mt. Pleasant Maintenance Yard Irerracon September 25, 2019 Terracon Project No. 71177023 1.6 Site Regulatory Status NCDEQ issues a Notice of Regulatory Requirements (NORR) that indicated the site's risk ranking was "High" (NCDEQ 2018). The NORR stated the following requirements: sample the existing on -site monitoring wells on a semi-annual basis (May and November); and sample water supply wells within 1,000 feet of the site. The NORR indicated a monitoring report summarizing the requested activities should be submitted to the NCDEQ by November 30, 2018. Terracon submitted a request for an extension to Ms. Trudy Beverly of the NCDEQ — Mooresville Regional Office. Ms. Beverly granted an extension until December 14, 2018. NCDEQ indicated that the next semi-annual sampling event should occur in May 2019 and the monitoring report summarizing the requested activities be submitted by June 30, 2019 (NCDEQ 2019). Terracon submitted a request for an extension to Ms. Trudy Beverly of the NCDEQ Mooresville Regional Office. Ms. Beverly granted an extension until September 27, 2019. 1.7 Objectives and Scope of Work The objective of the scope of work was to monitor the dissolved phase plume conditions and sample supply wells. This report contains a summary of the following activities and results: sampling of the existing monitoring well network; sampling of supply wells within 1,000 feet of the source area; and recommendations for future site activities. 1.8 Standard of Care Terracon's services were performed in a manner consistent with generally accepted practices of the profession undertaken in similar studies in the same geographical area during the same time period. Terracon makes no warranties, either express or implied, regarding the findings, conclusions, or recommendations. Please note that Terracon does not warrant the work of laboratories, regulatory agencies, or other third parties supplying information used in the preparation of the report. These services were performed in accordance with the scope of work agreed with you, our client, as reflected in our proposal. 3 Responsive ■ Resourceful ■ Reliable Groundwater Monitoring Report Irerracon NCDOT Mt. Pleasant Maintenance Yard September 25, 2019 Terracon Project No. 71177023 1.9 Additional Scope Limitations Findings, conclusions, and recommendations resulting from these services are based upon information derived from the on -site activities and other services performed under this scope of work; such information is subject to change over time. Subsurface conditions may vary from those encountered at specific borings or wells or during other surveys, tests, assessments, investigations, or exploratory services; the data, interpretations, findings, and our recommendations are based solely upon data obtained at the time and within the scope of these services. 2.0 RECEPTOR INFORMATION 2.1 Private Water Supply Wells Terracon conducted a windshield water supply well survey on February 3, 2017 in an attempt to locate water supply wells within a 1,500-foot radius from the site boundary. During the visual reconnaissance, properties were assumed to have a water supply well if a wellhead cover was observed, such as faux rock, concrete block, or ornamental `wishing well' style structures. Results are summarized on Table 1 and Figure 3. Terracon identified the following items: The service area provided by the Town of Mt. Pleasant Water and Sewer Department includes properties within a 1,500-foot radius of the site. Visual evidence of four (4) private water supply wells was identified based on the reconnaissance survey (Figure 3). Two (2) water supply wells were identified within a 1,000-foot radius of the site. Terracon contacted the Town of Mt. Pleasant Water and Sewer Department in an effort to determine if developed properties identified within a 1,500-foot radius of the site had a water account. Based on information provided by Ms. Amy Schueneman of the Town of Mt. Pleasant, the properties within the 1,500-foot radius to the north and one property to the south of the site are not connected to municipal water. There are two water supply wells (WSW-2 and WSW-3) located between the 500 foot and 1,000 foot -radius. There are potentially four water supply wells (WSW- 1, WSW-4, WSW-5 and WSW-6) located between the 1,000 foot and 1,500-foot radius. Property owners located greater than 1,000 feet from the source area were not directly contacted nor were water supply well questionnaires issued to property owners. As such, the use of each suspected well (potable water or irrigation) located greater than 1,000 feet from the site was not confirmed. 4 Responsive ■ Resourceful ■ Reliable Groundwater Monitoring Report NCDOT Mt. Pleasant Maintenance Yard I rerracon September 25, 2019 Terracon Project No. 71177023 2.2 Surface Water Surface water in the vicinity of the site is part of the Yadkin -Pee Dee River Basin. Dutch Buffalo Creek is located approximately 300 feet to the west of the source area. A pond is also located approximately 400 feet to the north of the source area. Surface water runoff at the site generally flows to the west and southwest towards Dutch Buffalo Creek that is located along the west side of the property. Surface water features are shown on an excerpt from the Mount Pleasant, NC 7.5- Minute Topographic Quadrangle Map, which is depicted on Figure 1. 2.3 Land Use and Places of Public Gathering Terracon did not identify properties considered places of public gathering within 1,500 feet of the site. According to the Cabarrus County GIS database, land use within 1,500 feet of the site is primarily residential and agricultural with some light commercial. 3.0 FIELD ACTIVITIES AND METHODS Sampling activities were conducted in general accordance with NCDEQ's requests (2018 and 2019). Field activities conducted during the August 2019 field events included collection of water level measurements, groundwater samples from 10 monitoring wells, and an attempt to collect a groundwater sample from two water supply wells (WSW-2 and WSW-3). Site wells are shown on Figure 2 and supply wells are shown on Figure 3. 3.1 Water Supply Well Sampling Terracon was unable to collect samples from the water supply wells located within 1,000 feet of the site (WSW-2 and WSW-3) during the August 2019 sampling event. Supply wells located greater than 1,000 feet (wells WSW-1, WSW-4, WSW-5 and WSW-6) from the source area were not included in the August 2019 sampling event per the NCDEQs September 2018 NORR. Terracon staff knocked on the door of the residence where WSW-2 is located but a minor answered the door and the property owner was not home to authorize sampling. The property owner of WSW- 3 answered the door but stated he was not interested in having his well sampled. 3.2 Site Inspection and Well Network Evaluation Terracon conducted an inspection of site monitoring wells. Monitoring well construction details are provided on Table 2. The following summarizes observations: Several wells (MW-2, MW-3, MW-4, and TP-3) could not be located and were likely paved over based on information gathered from discussions with NCDOT employees at the site office. Based on available historical documents, these wells were last located in 1996. 5 Responsive ■ Resourceful ■ Reliable Groundwater Monitoring Report NCDOT Mt. Pleasant Maintenance Yard Irerracon September 25, 2019 Terracon Project No. 71177023 Monitoring well MW-6 was not able to be sampled. The well appears to be constructed of corrugated plastic pipe and the well is not vertical. MW-6 bends at approximately three feet below grade which prevented the purging and sampling of the well. New monitoring wells MW-4R and MW-6R were installed on November 3, 2017 to replace MW-4 and MW-6. The majority of the wells were in good condition. During the August 2019 groundwater sampling event, water level measurements and groundwater samples were collected from the following nine monitoring wells: Shallow monitoring wells: MW-1 MW-4R MW-5 Deep monitoring well: MW-10 3.3 Water Level Measurements MW-6R MW-9 MW-7 TP-1 MW-8 TP-2 Water level measurements were collected from accessible site monitoring wells on August 14, 2019 to estimate the groundwater flow direction and horizontal and vertical hydraulic gradients. The water levels were measured with an electronic water level probe that was decontaminated before and after each use. The water level measurements were converted to water level elevations using existing top -of -casing elevation data for each well (Table 2). The water level elevations were used to prepare a water level contour map to estimate the shallow groundwater flow directions at the site, as discussed in Section 4.1 of this report. 3.4 Groundwater Sample Collection Groundwater samples were collected using a peristaltic pump. Low flow purging and sampling techniques were used to the extent practical for each well. During purging, the field geochemical parameters of temperature, pH, conductivity, dissolved oxygen (DO), and oxidation-reduction potential (ORP) were measured using a handheld YSI 556 multiparameter probe units. Purging continued until pH and conductivity parameters stabilized. Table 3 summarizes indicator parameter measurements of temperature, pH, specific conductance, DO, and ORP. Sampling equipment was thoroughly decontaminated with phosphate -free soap and distilled water prior to fieldwork and between each well to prevent cross -contamination. New polyethylene tubing was used during the purging and sampling of each monitoring well. Decontamination water and purge water was poured on the land surface.

Pleasant Maintenance Yard I rerracon September 25, 2019 Terracon Project No. 71177023 3.5 Sample Analysis Once collected, the groundwater samples were placed in appropriately labeled containers and packed on ice pending delivery to Shealy Environmental Services, Inc. (Shealy). Water samples collected in the field remained in the presence of a project representative until picked up by Shealy personnel and delivered to the laboratory in West Columbia, South Carolina. A completed chain - of -custody record was provided with the cooler containing groundwater samples. The following analytical methods were requested on the chain -of -custody for the wells sampled in August 2019: Volatile organic compounds (VOCs) by EPA Method 8260, Semi -volatile organic compounds (SVOCs) by EPA Method 8270, and MADEP Methods extractable petroleum hydrocarbons (EPH) and volatile petroleum hydrocarbons (VPH). 3.6 Quality Assurance/Quality Control Samples The quality assurance/quality control (QA/QC) sampling included one trip blank. A QA/QC sample was submitted to the laboratory for analysis of VOCs by EPA Method 8260. 4.0 RESULTS Field and laboratory analytical results from the soil and groundwater sampling events conducted in August 2019 are discussed in detail below. Laboratory analytical reports from Shealy were reviewed and validated to ensure that they met specific data -quality objectives. Laboratory analytical results are provided in Appendix A. 4.1 Groundwater Flow System Water level measurements were collected from the site monitoring wells on August 14, 2019. The depth -to -water measurements and the converted water level elevations are listed in Table 2. Depth to water measurements for the shallow wells (10 to 15 feet bls) ranged from approximately 3.60 to 7.91 feet bls. Water elevations were used to produce a potentiometric surface elevation map for the shallow wells (Figure 4). Based on the water level measurements collected in August 2019, the groundwater flow direction in the shallow aquifer zone appears directed to the north. The groundwater flow direction is generally consistent with historical site data. Shallow groundwater had a horizontal gradient of approximately 0.023 feet per foot (ft/ft). 7 Responsive ■ Resourceful ■ Reliable Groundwater Monitoring Report NCDOT Mt. Pleasant Maintenance Yard I rerracon September 25, 2019 Terracon Project No. 71177023 4.2 Groundwater Analytical Results Laboratory analytical results and field parameter results from the August 2019 sampling event are described below. Constituent concentrations in groundwater are presented in Table 4. Groundwater analytical results for VOCs, SVOCs, EPH, and VPH were compared with their NCAC 2L groundwater quality standards (2L standards). 4.2.1 Monitoring Well Network Groundwater samples were collected from 10 permanent monitoring wells on August 14, 2019. Groundwater concentrations in the samples collected from the permanent monitoring well network are presented in Table 4. 4.3 Evaluation for Vapor Intrusion Based on the Interstate Technology and Regulatory Council (ITRC) Petroleum Vapor Intrusion (PVI) guidance, additional evaluation of the PVI pathway for the dissolved -phase plume is not warranted. The on -site buildings are not likely at potential risk for PVI based on the observed groundwater concentration data and average vertical extent of the vadose zone at the site. 4.4 Quality Control The trip blank sample did not contain compounds at concentrations above laboratory method detection limits. A copy of the laboratory analytical report is provided in Appendix A. 4.5 Data Review and Validation This section provides an evaluation of the laboratory analytical data for the completeness of data package deliverables. Additionally, field data were reviewed to verify completion of required documentation. A copy of the laboratory analytical reports is provided in Appendix A. Field activities were documented on groundwater sampling logs. Groundwater samples were appropriately labeled, stored in sample containers on ice, and delivered to Shealy in good condition and properly preserved. The sample container chain -of -custody forms were forwarded with the samples to the analytical laboratory. The samples were analyzed for parameters as detailed in Section 3.5. For the August 2019 sampling event, one trip blank accompanied the cooler sent to the laboratory for analysis of VOCs by EPA Method 8260. VOCs were not detected in trip blank. EPH constituents (C9-C18 Aliphatic range) were detected in the method blank for the prep batch 8 Responsive ■ Resourceful ■ Reliable Groundwater Monitoring Report Irerracon NCDOT Mt. Pleasant Maintenance Yard September 25, 2019 Terracon Project No. 71177023 that contained samples MW-1, MW-4R, MW-5, MW-6R, MW-7, MW-8, MW-9, MW-10, TP-1 and TP-2. Samples MW-1, MW-4R, MW-5, MW-7 and MW-10 did not contain detections of the target analyte; therefore, the laboratory did not re -extract the samples. Samples TP-1, TP-2, MW-6R, MW-8, and MW-9 had detections of C9-C18 Aliphatic; therefore, the samples were re -extracted and re -analyzed outside of holding time. Both sets of data are included in the laboratory analytical report provided in Appendix A. Although samples were analyzed outside of hold time after re -extraction, the data associated with samples TP-1, TP-2, MW-6R, MW-8, and MW-9 is believed to be a reflection of on -site conditions. After re -extraction of select samples, the sample criteria were met. The surrogate, laboratory control sample, and matrix spike and matrix spike duplicate (MS/MSD) recoveries and precision on client samples were all within the advisory limits. MS/MSDs that were performed on non -project samples were not evaluated because matrix similarity to project samples could not be assumed. 5.0 FINDINGS AND RECOMMENDATIONS The findings of this report are as follows: Groundwater in the shallow aquifer (3 to 25 feet bls) is estimated to flow north; C9-C22 Aromatics were detected at a concentration above its 2L Standard in MW-6R. Compounds were not detected above 2L Standards in the remaining nine monitoring wells sampled; Terracon was unable to collect samples from two water supply wells (WSW-2 and WSW- 3) during the August 2019 sampling event. The on -site buildings are not likely at potential risk for PVI based on the observed groundwater concentration data and average vertical extent of the vadose zone at the site. Based on the current and historical results, Terracon offers the following recommendations: Conduct at least one (1) additional sampling event of monitoring well network to monitor for temporal trends particularly in monitoring well MW-6R. Abandon damaged monitoring well MW-6. 6.0 REFERENCES ECS, 1997. Engineering Consulting Services, Ltd (ECS).
