The adjoining properties are commercial and residential. No potable water supply wells were identified within a 1,000-foot radius of the site. Municipal water is available to the site and surrounding properties. The site has a risk classification because free product is present in monitoring wells MW-1 and MW-8A. In August 2017, the sorbent socks were removed from monitoring wells. On February 6, 2018, four monitoring wells (MW-1, MW-2A, MW-8A, and MW-9) were gauged, purged and/or sampled. Concentrations of requested method constituents that exceeded the Maximum Allowable Concentrations specified in T15A NCAC 2L.0202 were reported in the ground water samples collected from MW-1, MW-2A, MW-8A, and MW-9. None of the reported contaminant concentrations exceeded the Gross Contamination Levels. Therefore, no further assessment should be required.

According to available information, four 3,000-gallon and one 6,000-gallon gasoline underground storage tanks (USTs) were removed from the site in May 1993. A total of eighteen Type II monitoring wells (MW-1, MW-2A, MW-3A, MW-4 through MW-7, MW-8A, and MW-9 through MW-18) and two Type III monitoring wells (TW-1 and TW-2) were installed at the site during past ground water assessment activities. According to the historical information, monitoring wells MW- 6, MW-7, and TW-1 have been destroyed. Previous assessment and remediation activities were conducted by other consultants. Geological Resources, Inc. (GRI) cannot verify the accuracy of information obtained from previous reports, but for the purposes of this report, it is assumed to be correct. Please refer to previous submittals for further historical information regarding the site. 2.0 CURRENT SITE ASSESSMENT This report presents the results of ground water sampling activities conducted on February 6, 2018 at the Former Sunrise BP site in Goldsboro, Wayne County, North Carolina (Figures 1 and 2). The activities were conducted in accordance with GRI Proposal Number 17-627 which was submitted to the North Carolina Department of Environmental Quality (NCDEQ) on January 11, 2018, and approved as Task Authorization Number 10679-29 on January 18, 2018. The purpose of the scope of work was to obtain current ground water quality data for the site since removing sorbent socks in August 2017. 3.0 GROUND WATER QUALITY Four Type II monitoring wells (MW-1, MW-2A, MW-8A, and MW-9) were gauged on February 6, 2018. The depths to ground water in the Type II monitoring wells gauged during the February 2018 sampling event ranged from 6.07 to 6.63 feet below the tops of well casings. Ground water elevations in the Type II monitoring wells relative to a temporary benchmark with an assumed datum of 100.00 feet ranged from 93.93 to 94.81 feet. A Site Map showing the location of the monitoring wells has been included as Figure 3. A Water Table Surface Map has been included as Figure 4. A summary of well construction information and ground water elevation data is presented in Table 1. Laboratory analyses were performed on the ground water samples for volatile organic compounds using EPA Method 602. Concentrations of BTEX constituents, MTBE, and/or naphthalene that exceeded the maximum allowable concentrations (MACs) specified in T15A NCAC 2L.0202 (2L) were reported in the 2 ground water samples collected from MW-1, MW-2A, MW-8A, and MW-9. None of the reported concentrations exceeded the Gross Contamination Levels (GCLs). A Ground Water Quality Map based on data from the February 2018 sampling event has been included as Figure 5. A summary of ground water sample analytical results is presented in Table 2. A copy of the complete laboratory analytical report has been included as Appendix A. 4.0 CONCLUSIONS AND RECOMMENDATIONS  In August 2017, sorbent socks were removed from monitoring wells.  In February 2018, monitoring wells MW-1, MW-2A, MW-8A, and MW-9 were gauged and sampled. The average depth to ground water in the Type II monitoring wells in February 2018 was 6.25 feet.  Concentrations of BTEX constituents, MTBE, and/or naphthalene that exceeded the MACs were reported in the ground water samples collected from MW-1, MW-2A, MW-8A, and MW-9.  None of the reported concentrations exceeded the GCLs. Therefore, no further assessment should be required. 5.0 LIMITATIONS This report has been prepared for the exclusive use of Castleberry’s, Inc. for specific application to the referenced site in Wayne County, North Carolina. The assessment was conducted based on the scope of work and level of effort desired by the NCDEQ and with resources adequate only for that scope of work. Our findings have been developed in accordance with generally accepted standards of environmental practices in the State of North Carolina, available information, and our professional judgment. No other warranty is expressed or implied. The data that are presented in this report are indicative of conditions that existed at the precise locations sampled and at the time the samples were collected. In addition, the data obtained from samples would be interpreted as being meaningful with respect to parameters indicated in the laboratory report. No additional information can logically be inferred from these data. Please note that field data collected prior to the November 2009 receptor survey update, free product evaluation, and ground water sampling events were not obtained under the supervision of GRI. Although the accuracy of this information cannot be verified, for the purpose of this report GRI assumes that it is correct.
