r <br /> . Ground Water Monitoring Well Installation Report - <br />;' Is` Quarter 2000 <br /> GREWAL'S MARKET <br /> 4100 East Fremont Street, Stockton, California <br /> 1.0. INTRODUCTION <br /> i' Advanced GeoEnvironmental, Inc. (AGE) has prepared this Ground Monitoring Well Installation <br /> Report documenting well installation and soil sampling activities at 4100 East Fremont Street(site), <br />' Stockton, California. The location of the site is illustrated in Figure 1; general features at the site are <br /> illustrated in Figure 2. <br />' The scope of work of this investigation included installation of three ground water monitoring wells <br /> with the objective of assessing the impact of petroleum hydrocarbons to soil and ground water. This <br /> report is prepared in accordance with guidelines established by the San Joaquin County Public <br /> Health Services - Environmental Health Division (PHS-EHD) and by the Central Valley Regional <br /> Water Quality Control Board for investigation of underground storage tank(UST).sites. Background <br /> information is summarized in the Preliminary Investigation and Evaluation Report, dated 27 <br />' September 1999 and prepared by AGE. <br />'' • 2.0. PROCEDURES <br /> In February 2000, monitoring wells MW-1, MW-2 and MW-3 were installed on-site; soil sampling <br /> was performed at five-foot intervals during drilling activities. Ground water monitoring well <br /> installation procedures for the site were outlined in Monitoring Well Installation Work Plan - <br /> September 1999, dated 01 September 1999, prepared by AGE and approved by the PHS-EHD by <br /> letter dated 23 September 1999. <br /> 2.1. DRILLING AND SAMPLING <br /> On 01 and 02 February 2000,three soil borings/monitoring.wells (MW-1, MW-2 and MW-3) were <br /> advanced on-site as part of site assessment activities related to the former USTs at the site. Soil <br /> borings MW-1, MW-2 and MW-3 were advanced vertically to depths of 70 feet below surface grade j <br />' (bsg). The soil borings were advanced utilizing a CME-75 high torque, truck-mounted drill rig <br /> equipped with 8-inch diameter hollow-stem augers. Soil cuttings were stockpiled on and covered by <br /> plastic sheeting at the site; the soil boring/monitoring well locations are depicted in Figure 2. <br />' 2.2. SOIL SAMPLE COLLECTION <br /> Discrete soil samples were collected at 5-foot intervals beginning at 10 feet bsg from all three soil <br /> Advanced GcoEnvironmentai,Inc. <br />
