Post Office 160 Elizabethtown, North Carolina 28337 Prepared by: Geological Resources, Inc. 3502 Hayes Road Monroe, North Carolina 28110 (704) 845-4010 August 14, 2017 Holden McClenney Rae Troiano Brown, P.G. Staff Scientist Project Manager 704.698.1254 EXECUTIVE SUMMARY Han-Dee Hugo #5 is located at 1210 North Main Street in Bladenboro, Bladen County, North Carolina. The site is currently an active petroleum retail facility and convenience store. Three 8,000-gallon gasoline USTs, one 8,000-gallon fuel oil, one 8,000-gallon diesel, and one 2,000-gallon kerosene USTs are in use at the site. A release at the site was discovered during Environmental Site Assessment activities. Contaminated soil was discovered during site renovations in May and June 2012. A total of 2,162.49 tons of soil was removed from the site. The site is ranked as high risk because one potable water supply well (WSW-7) was identified within 1,000-radius of the site. Another water supply well (WSW-10) was identified within a 1,500-foot radius of the subject site. Three irrigation wells (WSW-1, WSW-2, and WSW-5) were confirmed within 1,000 feet of the site. There are no water supply wells within 250 feet of the site. Municipal water is available to all properties in the area. A well abandonment agreement was sent to the owner of WSW-7 who denied abandoning her well and connecting to municipal water. On June 6, 2017, GRI personnel installed five Type II monitoring wells at the site to assess the Gross Contaminant Level plume in the vicinity of MW-11. On June 20, 2017, five Type II monitoring wells and one Type III monitoring well were gauged, purged, and sampled. Free product was not measured in any monitoring well during the June 2017 sampling event. Concentrations of individual BTEX constituents, MTBE, naphthalene and/or di-isopropyl ether that exceeded the maximum allowable concentrations specified in T15A NCAC 2L.0202 were reported in the ground water samples collected from MW-14, MW-15, MW-16, MW-17 and MW-18. None of the report contaminant concentrations exceeded GCLs. Based on this information, the site risk classification should remain high risk due to GCL concentrations. GRI recommends conducting a ground water assessment in six months to include nutrient analysis. Subsequent to the assessment, a corrective action feasibility study should be conducted for the site.

The site is currently an active petroleum retail facility and convenience store. Three 8,000- gallon gasoline, one 8,000-gallon fuel oil, one 8,000-gallon diesel, and one 2,000-gallon kerosene USTs are in use at the site. According to the Phase II Limited Site Assessment (LSA) Report (April 25, 2005) submitted by CBM Environmental Services, Inc., a release at the site was discovered during Environmental Site Assessment activities. Four shallow monitoring wells (MW-1 through MW-4) and one deep monitoring well (TW-1) were installed during LSA activities. Contaminated soil was discovered during site renovations in May and June 2012. A total of 2,162.49 tons of soil was removed from the site. GRI submitted an Initial Action Abatement Report on August 27, 2012. In December 2012 and January 2013, during the Comprehensive Site Assessment (CSA), monitoring wells MW-1R, MW-2R, MW-4R, MW-5 through MW-13, and TW-1R were installed. The CSA report was submitted by GRI in May 2013. Monitoring wells MW-14 through MW-18 were installed on June 6, 2017. The site is ranked as high risk because one potable water supply well (WSW-7) was identified within 1,000-radius of the site. Another water supply well (WSW-10) was identified within a 1,500-foot radius of the subject site. Three irrigation wells (WSW-1, WSW-2, and WSW-5) were confirmed within 1,000 feet of the site. There are no water supply wells within 250 feet of the site. Municipal water is available to all properties in the area. In October 2013, a well abandonment agreement was sent to the owner of WSW-7 who denied abandoning her well and connecting to municipal water. Site Vicinity Map showing the locations of water supply wells is included as Figure 2. A Site Map showing the locations of the monitoring wells and the structures on-site and on surrounding properties has been included as Figure 3. In addition, concentrations of benzene and MTBE reported in MW-11 have exceeded the gross contaminant levels (GCLs) since 2013. 2.0 CURRENT SITE ASSESSMENT The purpose of this report is to present the results of ground water sampling activities conducted at the site. The activities were conducted in accordance with GRI Proposal Number 17-337 which was submitted to the NCDEQ on May 23, 2017, and approved as Task Authorization Number 29175-9 on June 15, 2017. The current scope of work includes obtaining current ground water quality data for the GLC plume assessment in the vicinity of MW-11. 2 3.0 MONITORING WELL INSTALLATION On June 6, 2017, GRI personnel installed five Type II monitoring wells (MW-14 through MW-18) to a total depth of fifteen feet below ground surface utilizing a mobile drill rig with six inch solid stem augers. Locations of the monitoring wells are shown on Figure 3. A summary of well construction information is presented in Table 1. Well installation records are included in Appendix A. 4.0 GROUND WATER SAMPLING ACTIVITIES 4.1 Site Hydrogeology On June 20, 2017, monitoring wells MW-14 through MW-18 were gauged, purged and/or sampled. The depths to ground water in the Type II monitoring wells during the June 2017 sampling event ranged from 5.61 to 6.36 feet below the tops of well casings. Ground water elevations in the newly installed Type II monitoring wells relative to a temporary benchmark with an assumed datum of 100.00 feet ranged from 95.73 to 96.40 feet. The locations of the monitoring wells are shown on Figure 3. A Water Table Surface Map based on data obtained from the Type II wells in June 2017 is included as Figure 4. A summary of well construction and gauging information is presented in Table 1. 4.2 Ground Water Sampling Laboratory analyses were performed on the ground water samples collected from the monitoring wells and water supply well during the June 2017 sampling event for volatile organic compounds by EPA Method 602. Concentrations of individual BTEX constituents, MTBE, naphthalene and/or di-isopropyl ether that exceeded the maximum allowable concentrations (MACs) specified in T15A NCAC 2L.0202 were reported in the ground water samples collected from MW-14, MW-15, MW-16, MW-17 and MW-18. None of the reported contaminant concentrations exceeded the GCLs. A Ground Water Quality Map based on data from the June 20, 2017, sampling event has been included as Figure 5. A summary of ground water sampling analytical results is presented in Table 2. A complete laboratory report has been included in Appendix B. 5.0 CONCLUSIONS AND RECOMMENDATIONS  In July 2017, five monitoring wells (MW-14 through MW-18) were installed in the vicinity of MW-11 in order to assess the GCL plume.  Concentrations of individual BTEX constituents, MTBE, naphthalene and/or di-isopropyl ether that exceeded the MACs were reported in the ground water samples collected from MW-14, 3 MW-15, MW-16, MW-17 and MW-18.  None of the reported contaminant concentrations exceeded the GCLs.  Based on this information, the site risk classification should remain high risk due to GCL concentrations. GRI recommends conducting a ground water assessment in six months to include nutrient analysis. Subsequent to the assessment, a corrective action feasibility study should be conducted for the site. 6.0 LIMITATIONS This report has been prepared for the exclusive use of Sampson-Bladen Oil Company, Inc. for specific application to the referenced site in Bladen County, North Carolina. The assessment was conducted based on the scope of work and level of effort specified 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 geology and hydrogeology 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.
