In the CountyAssessors Records, for the <br /> t years 1963, 1968 and 1974 is a listing of a 500-gallon underground fuel storage tank (UST) <br /> valued to the property. No record was found as to the disposition of the tank. However, it <br /> was reportedly filled with cement and left in place._ A site inspection revealed evidence of <br /> what appears to be a former fill pipe plugged with concrete`and a former pump dispenser pad <br /> capped with concrete. A magnetometer survey showed evidence of a small"size tank oriented <br /> r+ west of the fill pipe structure. (see Figures 1 & 2). <br /> On July 12, 2005, V&W Drilling and Geological Technics Inc. (GTI) personnel mobilized to <br /> the site to advance three GeoProbe boreholes (GP-1, GP-2 &GP-3;). The locations are shown <br /> on the Site Map (Figure 2). Each of the three GeoProbe borings was advanced to a total <br /> depth of 20 feet bgs. Two (2) soil samples from each boring were selected for laboratory <br /> analysis (see- Table l for laboratory results and Appendix; C for data sheets). Logs were <br /> produced for each of the boreholes and these logs are attached as Appendix B. <br /> GTI's preliminary interpretation of the approximate extent of the contamination and soil <br /> types that was included in our August 3, 2005 "Tank Closure Iniestigation" is presented in <br /> Figure 3. GTI has developed the following work plan to further define the lateral and vertical <br /> extent of gasoline and diesel range petroleum hydrocarbons at the site. <br /> 3' <br /> f <br /> I <br /> n <br /> � 1911 <br />
