I <br /> The work scope included destroying three off-site groundwater monitoring wells, MW-12, MWA 3 and ? <br /> MW-14, located on the northern adjacent lot(Figure 1,Attachment 1). The work was performed as <br /> described in Groundwater Technology's letter, Request to Destroy Three Groundwater Monitoring <br /> if <br /> Weiss, dated June 14, 1994. All work was conducted in accordance with State of California Water Well <br /> Standards, Bulletin 74-90, Section 461 for destruction of monitoring wells, and in accordance with <br /> San Joaquin County Public Health Services, Environmental Health Division (SJCPHS-EHD) <br /> requirements. <br /> I � i#I The wells were destroyed after laboratory results of groundwater indicated that no concentrations of <br /> benzene,toluene, ethylbenzene avid xylenes (BTEX), and total petroleum hydrocarbons-as-gasoline <br /> 1. <br /> (TPH-G)were detected in the three wells. In addition,the wells were not needed as data points for <br /> potentiometric map generation as part of quarterly reporting. <br /> 1 <br /> Monitoring Well Destruction st I <br /> On April 24, 1995, Groundwater TecHnology personnel supervised the destruction of three (3) <br /> 4-inch-diameter groundwater monitoring wells. Depth to water in the wells was approximately 4 feet <br /> below ground surface (BGS)with screened intervals from approximately 10 to 20 feet BGS. <br /> ;t <br /> 0105dest fir(SINS) <br /> , <br /> Offices throughout the US,Canada and Overseas <br />
