(AGE) has prepared this report for the destruction of three (3) ground water monitoring wells at 244 West Harding Way, Stockton, California (site). The site location is depicted on Figure 1; site structures and former well locations are depicted on Figure 2. INTRODUCTION/BACKGROUND Ground water monitoring wells had been installed as part of a subsurface investigation of the former underground storage tank (UST) area at the site. Two-inch diameter ground water monitoring wells MW-1 through MW-3 were installed to depths of 45 feet below surface grade (bsg). Monitoring wells were destroyed as outlined in the AGE-prepared, Well Destruction Work Plan, dated 20 October 2011. All three wells were destroyed under San Joaquin County Environmental Health Department boring permit, which has been included in Appendix A. PROCEDURES Well destruction activities were performed on 12 January 2012 by All Well Abandonment of Sacramento,California. Ground water monitoring wells MW-2 and MW-3 were destroyed by pressure grouting the well columns with Portland Type II cement (six gallons water for every 94-pound sack of portland cement )and over-drilling the upper three feet of the well using hollow stem augers. Ground water monitoring well MW-1 was removed by over- drilling the well to total depth (45 feet bsg) with 8-inch (2-inch diameter monitoring well) X S1t.€tt Rot.d • 5€ircktoaIt.
