ECS Carolinas, LLP (ECS) recently completed a Phase I Environmental Site Assessment (ESA) of the site in September 2105 (ECS Project No. 09.26039). The site consists of an approximate 1.45 acre tract identified as Parcel Identification Number (PIN) 371107792430. The site currently contains an approximate 3,680 square foot commercial building, occupied by Direct TV and an automobile repair business (southern portion of the site); two single family residences (northern portion of the site); asphalt parking areas; and, landscaped areas. During the ESA site reconnaissance, a dark black stained bush and soil was observed near the southeastern corner of the residence located on the northeast corner of the property. The commercial building was reportedly occupied by various commercial businesses, including Old Sealtest Dairy and DRR Properties, LLC and Harold King. The Direct TV portion of the building contained offices and storage areas. The automotive repair portion of the building contained an automotive repair bay/workshop and a restroom. De minimis staining was observed on the concrete floor in this area; however, floor drains were not observed in the building and the spilled material had not left the concrete. According to interviews, the automobile repair business had been located on the site for approximately three months. Based on this information, the automobile repair business was not considered a recognized environmental condition (REC). An automobile repair facility was reportedly located on adjoining property east of the site from at least 1992 to 1999. Based on the proximity to the site, a release from this property could impact the site. Therefore, the former automobile repair facility represented a REC. A regulatory database search report was provided by Environmental Data Resources, Inc. (EDR). The EDR report identified the Old Sealtest Dairy site as having a documented release. We reviewed the North Carolina Department of Environmental Quality (NCDEQ) file for this incident. According to information in the file, a release was discovered during the removal of a 6,000 gallon gasoline UST, a 5,000 gallon gasoline UST, a 1,100 gallon diesel UST, and a 550 gallon fuel oil UST March 1997. Laboratory analysis of confirmation soil samples collected from the base of the excavations indicated that total petroleum hydrocarbons (TPH) were detected above state action levels. Approximately 50 cubic yards of petroleum impacted soil was removed from the former UST basins in September 1997. Laboratory analysis of confirmation soil samples did not identify petroleum constituents above detection limits. The NCDEQ issued a No Further Action letter for this incident, dated October 28, 2003. A soil and groundwater assessment was performed in October 2013 by Geological Resources, Inc. (GRI) in the area where the dispenser for the former gasoline USTs was located. The gasoline USTs and dispenser were located along the east side of the property. Laboratory analysis of soil and groundwater collected during the investigation did not detect petroleum compounds above detection limits in the soil or groundwater; however, tetrachloroethylene (Perc) and trichlorofluoromethane were discovered in the groundwater sample. Perc was detected above the 15A NCAC 02L Groundwater Quality Standards (NC2L standards). Trichlorofluoromethane was detected below the NC2L standard. The incident was transferred Soil and Groundwater Assessment Report Former Sealtest Dairy 2115 Highway 70 Southeast Hickory, Catawba County, North Carolina ECS Project No. 09.26039B November 4, 2015 2 to the Inactive Hazardous Site Branch (IHSB) due to the presence of Perc in the groundwater above the NC2L standard. Based on information in the file, additional assessment has not been performed. The Perc-impacted groundwater represented a REC of the site. ECS was contracted by Mr. Dan Uebelhor with InSite Real Estate, LLC to complete a soil and groundwater assessment at the site. Project information is based on a conversation between Mr. Uebelhor and Mr. John Stewart of ECS and the previously cited report. 2.0 FIELD ACTIVITIES 2.1 Introduction to Scope of Work The soil and groundwater assessment consisted of drilling and collecting soil and groundwater samples using a Geoprobe® drill rig. The drilling contractor used for this project was 3D Environmental Investigations, LLC. 2.2 Utility Clearance Prior to commencing with field activities, ECS contacted NC One-Call to locate and mark public utilities at the site. ECS also contracted with a private utility locator to locate private underground utilities at each parcel. Required separation distances between subsurface activities and marked utilities (typically 30-inches) were maintained during the field activities. 2.3 Geoprobe® Drilling Services The Geoprobe® consists of a hydraulic jack mounted on an all-terrain vehicle (ATV). The Geoprobe® is capable of driving various forms of groundwater and soil sampling probes into the ground to depths equivalent of auger refusal. 2.4 Geoprobe® Soil Boring The soil boring (SB-1) was advanced by hydraulically driving a five-foot long, 1.5-inch soil sampling probe into the soil in the area of stained soil adjacent to the bush. The location of the soil boring is shown on Figure 3. Prior to advancing the boring, the down hole equipment and Geoprobe® drill rig were decontaminated utilizing a high pressure steam cleaner that utilized municipal water. The down hole equipment and drill rig were decontaminated to prevent cross- contamination between boring locations. The soil sampling probe is lined with a disposable clear plastic tube, which is replaced with each five-foot interval. After the probe is driven, the clear plastic tube filled with soil is removed from the probe. The clear plastic tube is then cut open to remove the soil. 2.5 Soil Sample Collection and Preparation Soil samples were collected from a depth of three feet (SB1-3) and five feet (SB1-5) below ground surface. ECS visually classified the soils collected from each boring and screened the soil samples for relative levels of volatile organic vapors using a Thermo 2020 flame ionization detector (FID). Soil and Groundwater Assessment Report Former Sealtest Dairy 2115 Highway 70 Southeast Hickory, Catawba County, North Carolina ECS Project No. 09.26039B November 4, 2015 3 Each soil sample was transferred into new, clean resealable bags, and placed in a warm location for approximately ten minutes. The bag was opened slightly and the probe of the FID was inserted, and the bag immediately resealed using finger pressure. The meter of the FID was monitored and the reading recorded. The FID did not detect organic vapors in the samples. The sampler, wearing a new pair of disposable nitrile gloves for each sample, placed the samples in laboratory prepared containers. The sample containers were labeled and placed into protective packaging material and placed into a cooler with ice to maintain the samples at approximately 4 Celsius (C). The samples were transported to Research and Analytical Laboratories (R&A) in Kernersville, North Carolina and QROS Laboratories, LLC (QROS) in Wilmington, North Carolina for chemical analysis. Soil samples were analyzed for gasoline range organic (GRO) and diesel range organics (DRO) Total Petroleum Hydrocarbons (TPH) using ultraviolet fluorescence (UVF) by QROS and total chromium (Cr) and lead (Pb) using EPA Method 200.7 by R&A. Soil sample SB1-3 was also analyzed for hexavalent chromium (Cr+6) using EPA Method 7196. ECS maintained proper chain-of-custody (COC) procedures throughout the sample collection and transportation process. A Copy of the COCs is included in Appendix A. 2.6 Geoprobe® Groundwater Borings Groundwater borings GWB1 and GWB2 were drilled along the eastern property boundary in the vicinity where the PCE was previously detected. The sample locations are shown on Figure 3. The groundwater borings were advanced by hydraulically driving a four-foot long, one-inch diameter water-sampling probe into the soil to an approximate depth of five feet beneath the water table as estimated during drilling. The groundwater sampling probe is equipped with a stainless steel screen and a disposable drive point. The probe is driven to depth and then the rod is retracted to expose the screen. Groundwater then flows through the screen into the hollow probe rods. The groundwater is pumped to the surface using a peristaltic pump with dedicated plastic tubing lowered through the center of the probe rods. Upon completion, the groundwater boring was properly abandoned. 2.7 Groundwater Sample Collection and Preparation The groundwater samples were collected using the peristaltic pump and placed into laboratory prepared containers. The sample containers were labeled, placed into protective packaging material and placed into a cooler with ice to maintain the samples at approximately 4 Celsius (C). The samples were submitted to R&A for chemical analysis for volatile organic compounds (VOCs) using EPA Method 8260, semi-volatile organic compounds (SVOCs) using EPA Method 8270BNA (base neutrals and acid extractable), and total Cr and Pb. ECS maintained proper COC procedures throughout the sample collection and transportation process. Copies of the COCs are included in Appendix A.

Laboratory analysis detected total chromium and lead at concentrations above the laboratory reporting limits; however, the concentrations do not exceed their Inactive Hazardous Sites Branch (IHSB) Preliminary Residential Health-Based Soil Remediation Goal (SRG) or Protection of Groundwater SRG. Hexavalent chromium was not detected in soil sample SB1-3. A summary of the soil analytical results is presented in Table 1. The laboratory data sheets are included in Appendix A. 3.2 Groundwater Sampling Results Laboratory analysis of groundwater samples GWB1 and GWB2 did not detect VOCs or SVOCs above the laboratory quantitation limits. Laboratory analysis detected total Cr and Pb above their NC2LGWQS. A summary of the groundwater analytical results is presented in Table 2. The laboratory data sheets are included in Appendix A. 4.0 CONCLUSIONS Laboratory analysis did not detect DRO and GRO TPH above laboratory quantitation limits. Based on field observations, the oil that stained the soil and bush may have been from cooking oil. QROS did not detect the presence of petroleum hydrocarbons. The concentrations of total lead and chromium are typical for soil in the Piedmont of North Carolina. Laboratory analysis of the two groundwater samples did not detect targeted VOCs or SVOCs above the laboratory reporting limits. It is our opinion that the groundwater in the areas sampled has not been impacted by VOCs or SVOCs. Laboratory analysis of the two groundwater samples collected at the site detected total chromium and lead at concentrations that exceed their NC2LGWQS. Total chromium and lead were detected in the soil samples collected at the site, and the concentrations are indicative of naturally occurring concentrations. Because the groundwater samples were collected using a direct push sampler, there was sediment in the samples. Upon acidification of the samples (nitric acid is used a preservative), the metals in the soil can become more soluble and detected during analysis, providing a false positive. The concentrations of total chromium and lead in the groundwater samples are below what was detected in the soil samples. Because total chromium and lead are naturally present in the soil at the site and because there is no evidence of a release at the site, it is our opinion that the chromium and lead detected in the groundwater samples are naturally occurring and not indicative of a release.
