Weber Avenue, 3rd Floor <br /> Stockton, CA 95202 <br /> Subject: Monitoring Well Abandonment Summary at Gemelos-Paladine Mileage Center, <br /> 2421 Holly Drive, Tracy, California, Site Code: 1412 <br /> Dear Mr. Infurna: <br /> ATC Associates has prepared this letter on behalf of Elaine Kluve to summarize groundwater <br /> monitoring well abandonment activities at the above referenced site (Figure 1). This work was <br /> performed following Regional Water Quality Control Board's concurrence with San Joaquin <br /> County Environmental Health Division's (SJEHD's) request for No Further Action. <br /> On March 1, 2002, ATC supervised the abandonment of on-site monitoring wells MW1, MW2, and <br /> MW3 (Figure 2). The wells were abandoned by Gregg Drilling, a C57 licensed drilling company. <br /> The three monitoring wells were destroyed by overdrilling the casing and sandpack to depths of <br /> approximately 16 feet. <br /> Soil cuttings generated during well destruction activities were disposed of at Forward Landfill in <br /> Stockton, California on April 8, 2002. Two drums of rinsatelpurgate water were transported by <br /> American Valley Waste Oil on June 21, 2002 to Seaport Environmental in Richmond, California. <br /> Copies of the nonhazardous waste manifest are attached. A third drum of water was analyzed and <br /> determined to be non-detect, and was discharged to the surface at the site on June 21, 2002. <br /> Laboratory results are attached. <br /> All work was completed in accordance with ATC's Workplan for Destruction of Groundwater <br /> Monitoring Wells at Gemelos-Paladine Mileage Center, 2421 Holly Drive, Tracy, California, <br /> Site Code: 1412 dated February 5, 2002 and Site Safety Plan (SSP) dated February 2002. <br /> w:lwordprol92054.021reportslwellabandonmcnt 1 <br /> ENVIRONMENTAL, GEOTECHNICAL AND MATERIALS PROFESSIONALS <br />
