Monitoring Well Destruction Report <br /> First Student Bus Facility(Former A.W. Hayes Facility) <br /> 2005 Navy Drive—Stockton, CA <br /> SCOPE OF WORK <br /> On November 9, 2012, the four (4) 2-inch groundwater monitoring wells located on the <br /> Site were destroyed under permit issued by the San Joaquin County Environmental <br /> Health Department. A copy of the Permit for the destruction of the wells is included in <br /> Appendix A. The locations of the four (4) monitoring wells are illustrated on Figure 2 - <br /> Site Plan. <br /> The four (4) wells were destroyed by drilling out the 2-inch well casing using 8-inch <br /> hollow stem augers, and then filling in the former well borings using neat cement <br /> (Portland) to a depth of approximately 2-inches below ground surface (bgs). <br /> Groundwater was encountered in each of the four (4) monitoring wells at an average <br /> depth of approximately 12 feet bgs. The top 2-inches of each of the destroyed wells was <br /> then sealed using a concrete seal to match the existing surface grade. The soil and PVC <br /> well casing removed during the destruction of the wells were placed into new, 55-gallon, <br /> DOT approved drums and transported off-site for disposal under a Non-Hazardous Waste <br /> Manifest. A copy of the manifest for the transportation and disposal of the waste (soil <br /> and PVC well casing) generated during the destruction of the wells is included in <br /> Appendix C. <br /> LIMITATIONS <br /> Information presented herein was collected in accordance with procedures generally <br /> accepted for soil and groundwater investigations, and destruction of monitoring wells. <br /> As such, data and information collected for analysis and evaluation is limited by the level <br /> of completeness of information made available to KR Environmental, Inc. through the <br /> Client, past environmental investigations, State and County government documents, and <br /> guidelines and restrictions of other procedural information acquisition sources.
