Ground Water Monitoring Report Prepared on: December 9, 2021 U-Filler Up #26 Project Manager: William Regenthal, P. G. GRI Project No. 2964 ii EXECUTIVE SUMMARY The former U-Filler Up #26 site is located at 101 Smith Church Road in Roanoke Rapids, Halifax County, North Carolina. The site is currently owned by D. H. Roanoke, LLC and is operated by Walgreens as a drugstore. The site formerly operated as a petroleum retail facility. Three 12,000-gasoline USTs were removed from the site in October 1991. The adjoining properties are a mixture of single family residential and commercial properties. A CSA was completed in 2003. A CAP proposing air sparge and soil-vapor extraction was developed for this incident in 2003 but has not been fully implemented. On November 16, 2021, six Type II monitoring wells were gauged, purged and sampled. No free product was observed in the monitoring wells prior to sampling. Concentrations of individual BTEX constituents, MTBE, naphthalene, methyl chloride, isopropylbenzene, methylene chloride, n-propylbenzene, 1,2,4- trimethylbeneze and/or 1,3,5- trimethylbeneze that were above the MACs were reported in the ground water samples collected from MW-1, MW-4, MW-5, MW-9, MW-12 and MW-13. Concentrations of benzene reported in the ground water sample collected from MW-1 was above the GCL. Contaminant mass as the site has decreased by 40.4% since May 2018. Based on this information, the site incident can close once contaminant concentrations have been reduced to less than the GCL for benzene. The CAP that was developed in 2003 could be implemented at the site, however, a series of AFVR and/or MMPE events could be conducted at the site in order to reduce contaminant mass in core monitoring wells MW-1, MW-4 and MW-5. Since the site is an active Walgreens, soil excavation or the installation of additional wells is not practical and may not be allowed by the property owner. A feasibility study discussing the implementation of the 2003 CAP and/or ground water extraction events could be developed. ___________________________________________________________________________________________ Prepared by: Geological Resources, Inc.

GRI Project No. 2964 1 1.0 SITE HISTORY AND CHARACTERIZATION GRI presents the results of the November 2021 ground water sampling event at the U-Filler Up #26 site; located at 101 Smith Church Road in Roanoke Rapids, Halifax County, North Carolina (Figure 1). These activities were conducted in accordance with GRI Proposal No. 21-663, which was submitted to NCDEQ on October 28, 2021, and was approved as Task Authorization No. 7093-20 on October 29, 2021. NCDEQ correspondence associated with the incident is included as Appendix A. The site is currently owned by D. H. Roanoke, LLC and is operated by Walgreens as a drugstore. The site formerly operated as U-Filler Up #26, a petroleum retail facility. According to available information, three 12,000-gallon gasoline USTs were removed from the site in October 1991 by Applied Environmental Services, Inc. (AES). UST owner/operator information and UST system information are included as Tables 1 and 2, respectively. The Registered Tank Report is shown below: The site and surrounding area are a mixture of single family residential and commercial properties. The site contains one building and is primarily capped with concrete and landscaping. The overall topography at the site is relatively flat. Fifteen Type II and one Type III monitoring wells were installed at the site during previous ground water assessment and corrective action activities. The Type III monitoring well (MW-7) was abandoned in July 2019. A Site Vicinity Map showing the location of the site and surrounding property boundaries is included as Figure 2. A Site Map showing the locations of the monitoring wells and the structures on-site has been included as Figure 3. According to the November 12, 1991, Tank Closure Assessment completed by AES, contaminated soil encountered during UST closure activities was removed from the site and transported to a permitted disposal facility. Excavation activities ceased when ground water was encountered in the excavation basin at a depth of approximately 11.5 feet bgs. A CSA was completed in 2003. A CAP proposing an air sparge and soil-vapor extraction remediation system was developed in 2003, however it has not been fully implemented. ___________________________________________________________________________________________ Prepared by: Geological Resources, Inc. Ground Water Monitoring Report Prepared on: December 9, 2021 U-Filler Up #26 Project Manager: William Regenthal, P. G. GRI Project No. 2964 2 An AFVR event was conducted in February 2003 and a Free Product Evaluation/Recovery Event was conducted in August 2009. These activities were conducted by AES and others. Between January 2015 and October 2017, GRI supervised three AFVR events to remove free product from the site. 2.0 PRESENTATION OF CURRENT SITE ASSESSMENT INFORMATION/ COMPARISON TO HISTORICAL ASSESSMENT INFORMATION On November 16, 2021, six Type II monitoring wells (MW-1, MW-4, MW-5, MW-9, MW-12 and MW-13) were gauged, purged and sampled in accordance with the NCDEQ guidelines. Depths to ground water in the Type II monitoring wells ranged from 9.58 feet to 11.98 feet below the tops of well casings. Ground water elevations relative to a datum assumed by a previous consultant ranged from 131.09 to 132.64 feet. Ground water flow was generally to the south-southeast with a horizontal hydraulic gradient of approximately 0.03 feet per foot. Well construction and gauging information is presented in Table 3. A water table surface map is included as Figure 4. A summary of the current ground water gauging data is shown below: Well ID Screened Interval (x to y ft. BGS) Bottom of Well (ft.

Concentrations of individual BTEX constituents, MTBE, naphthalene, methyl chloride, isopropylbenzene, methylene chloride, n-propylbenzene, 1,2,4-trimethylbeneze and/or 1,3,5- trimethylbeneze that exceeded the MACs were reported in the ground water samples collected from MW- 1, MW-4, MW-5, MW-9, MW-12 and MW-13. Concentrations of benzene reported in the ground water sample collected from MW-1 was above the GCL. A summary of the analytical results for ground water samples collected on November 16, 2021, is presented in Table 4. A Ground Water Quality Map based on the November 2021 data is included as Figure 5. A complete report of laboratory analyses of the ground water samples collected from the monitoring wells during the November 2021 sampling event has been included as Appendix B. A summary of the current ground water analytical data is shown below: ___________________________________________________________________________________________ Prepared by: Geological Resources, Inc.

The contaminant plume is based on a benzene isoconcentration contour of 1 µg/L derived from the May 2018 ground water sampling event. The data indicates the contaminant mass has been decreased by 40.4% since May 2018. Please note that the contaminant mass cannot be calculated in wells containing free product; therefore, contaminant mass reduction calculations began with the May 2018 sampling event. Contaminant mass calculations have been included as Appendix C. A map of the contaminant mass area has been included as Figure 6. A chart depicting the overall trend in contaminant mass is shown below: The site is located along the eastern boundary of the Piedmont Physiographic Province of North Carolina. The water table has a seasonal high depth to water of approximately 7 to 13 feet bgs. Since the CAP has not been fully implemented for this site, cleanup milestones have not been established. ___________________________________________________________________________________________ Prepared by: Geological Resources, Inc. Ground Water Monitoring Report Prepared on: December 9, 2021 U-Filler Up #26 Project Manager: William Regenthal, P. G. GRI Project No. 2964 4 3.0 FREE PRODUCT REMOVAL Free product has historically been observed at this site. GRI has supervised three AFVR events since January 2015. These AFVR events have been conducted to remove free product. As of this report, a total of 0.47 gallons of vapor phase product have been recovered. Free product has not been detected at the site since the November 2017 sampling event. Past free product recovery events are summarized Table 5. 4.0 NATURAL ATTENUATION / NATURAL SOURCE ZONE DEPLETION STATUS No natural attenuation monitoring plan is currently in place at the site. Contaminant mass at the site continues to slowly decline since the last time free product was observed at the site (May 2018). Additional AFVR and/or MMPE events could be conducted at the site to remove contaminant mass, however, site restrictions may be prohibitive of conducting these activities. If contaminant concentrations can be reduced to less than the GCLs, then the site risk classification can be re-evaluated. Because the site is an active Walgreens, remediation activities will be restricted based on the site use. It is not likely that the property owner will allow excavation in the vicinity of MW-1, nor would they be likely to allow for the installation of additional monitoring wells in the parking lot of the drugstore. These factors should be considered with assessing the feasibility of implementing the proposed 2003 CAP. Additional ground water extraction events, via either AFVR or MMPE may be allowed. 5.0 CONCLUSIONS  On November 16, 2021, six Type II monitoring wells (MW-1, MW-4, MW-5, MW-9, MW-12 and MW-13) were gauged, purged and sampled. Ground water flow was generally to the south/ southeast with a horizontal hydraulic gradient of approximately 0.03 feet per foot.  Concentrations of individual BTEX constituents, MTBE, naphthalene, methyl chloride, isopropylbenzene, methylene chloride, n-propylbenzene, 1,2,4-trimethylbeneze and/or 1,3,5- trimethylbeneze were above the MACs reported in the ground water samples collected from MW- 1, MW-4, MW-5, MW-12 and/or MW-13. Concentrations of benzene reported in the ground water sample collected from MW-1 was above the GCL.  Contaminant mass at the site has decreased by 40.4% since May 2018. Contaminant mass at the site continues to slowly decline since the last time free product was observed at the site (May 2018).  Based on this information, the site incident can close once contaminant concentrations have been reduced to less than the GCL for benzene. The CAP that was developed in 2003 could be implemented at the site, however, a series of AFVR and/or MMPE events could be conducted at the site in order to reduce contaminant mass in core monitoring wells MW-1, MW-4 and MW-5.
