Advanced <br /> GeoEnvironmental, Inc . <br /> 05 August 2015 <br /> AGE Project No. 06-1463 <br /> Ms. Vera Fischer <br /> Central Valley Regional Water Quality Control Board <br /> 11020 Sun Center Drive # 200 <br /> Rancho Cordova, CA <br /> Subject: Well Destruction Work Plan <br /> SUPER CENTER MART <br /> 701 East Charter Way, Stockton, California <br /> Dear Ms. Fischer: <br /> At the request of Mr. Swaran Chouhan, Advanced GeoEnvironmental, Inc. (AGE) has <br /> prepared this work plan for the destruction of eleven (11) groundwater monitoring wells <br /> (MW-1 through MW-11), four vapor extraction wells (VW-1 through VW-4) and two <br /> groundwater extraction wells (EW-1 and EW-2). The site and the surrounding area are <br /> illustrated in Figure 1. Structures, soil borings, and well locations are illustrated in Figure <br /> 2. Historical soil, depth to water and groundwater analytical data are included in Tables <br /> 1 through 3. This work plan was prepared in accordance with California Regional Water <br /> Quality Control Board (CRWQCB) guidelines for the investigation of underground <br /> storage tank (UST) sites. <br /> This work plan also includes pre-remediation adsorbed mass estimates, pre- and post- <br /> remediation dissolved mass estimates and the estimated time for impacted groundwater <br /> to reach water quality objections as previously required by the San Joaquin County <br /> Environmental Health Department (SJCEHD), by letter dated 14 April 2015 <br /> (Appendix A). <br /> INTRODUCTION <br /> A total of eleven (11) groundwater monitoring wells (MW-1 through MW-11), four vapor <br /> extraction wells (VW-1 through VW-4) and two groundwater extraction wells (EW-1 and <br /> EW-2) remain installed on-site as part of the subsurface investigation of the former UST <br /> areas at 701 East Charter Way, Stockton, California. As part of site closure activities all <br /> remaining wells are proposed for destruction. <br /> 837 Shaw Road • Stockton,CA 95215 <br /> Telephone(209)467-1006• Fax(209)467-1118 <br />
