Hazelton Ave <br /> Stockton, California 95205 <br /> Subject: Summary Report, Groundwater Well Destruction Activities at Stagg High School, <br /> 1621 Brookside Road, Stockton, California 95207 <br /> Dear Mr. Yoakum: <br /> ATC Associates Inc. (ATC) has prepared this summary report for well destruction, on behalf of <br /> Stockton Unified School District, for the above referenced site. <br /> SITE LOCATION <br /> The site is located at located at 1621 Brookside Road, Stockton, California, as shown on <br /> Figure 1. <br /> SITE HISTORY <br /> Recently, a well was discovered at the Stagg High School property located at 1621 Brookside <br /> Road in Stockton, California. The well did not appear to be associated with an investigation <br /> previously conducted for an underground storage tank at the site. ATC contacted the San <br /> Joaquin County Environmental Health Department (SJCEHD) who indicated that the well was a <br /> piezometer that was permitted and owned by the Stockton Unified School District (SUSD). <br /> Since the well is no longer needed, SUSD requested a cost estimate to destroy the well. <br /> SCOPE OF WORK <br /> Well Destruction <br /> On October 29, 2012, ATC supervised the destruction of monitoring well MW1. Well MW1 was <br /> constructed with 2 inch diameter PVC and set at a depth of 19 feet bgs. The well abandonment <br /> was conducted by Cascade Drilling, L.P. State C57 License No. 938110. For well MW1, the <br /> entire length of casing was overdrilled with 8 inch augers with a 2 foot stinger. The casing was <br /> overdrilled to 19 feet bgs, then the augers retracted. Neat cement grout was poured into the <br /> borehole to within one foot of the surface, and then completed to match the surrounding area. <br /> S:\EnviromentA7292.02 Stagg HS\0003-Well abandon\Well abandonment summary rpt t <br />
