(GeoAudit) has <br /> prepared this Quarterly Report of activities at 16 South Cherokee <br /> Lane in Lodi, California. <br /> 2 .0 BACKGROUND <br /> Figure 1 shows the location of the site. Evidence of an <br /> unauthorized release of gasoline from underground fuel storage <br /> tanks (UST's) was encountered during the removal of three UST' s <br /> from this site in 1985 . Several environmental firms have been <br /> involved in the subsequent assessment of this release. The impact <br /> of this release on the vadose and saturated zones was initially <br /> investigated by J.H. Kleinfelder, Inc. (Kleinfelder) in the latter <br /> portion of 1985 . Between 1985 and 1990, Brown and Caldwell <br /> Consultants (BCC) performed additional field investigations. Field <br /> work was performed by PES Environmental in 1991, and in July of <br /> that year, PES submitted a Problem Assessment Report that <br /> summarized all previous investigations and proposed remedial <br /> Ialternatives. <br /> The PAR became the basis for an FRP, which was submitted by <br /> I GeoAudit in January 1992 . The FRP focused primarily on a discussion <br /> of recommended methods for soil and groundwater remediation. No <br /> additional field work was performed, and new data on vadose-zone <br />' contamination were not generated. <br /> San Joaquin County Public Health Services _ Environmental Health <br /> Division (PHS/EHD) and the Central Valley Regional Water Quality <br />' Control Board (CVRWQCB) found the FRP inadequate for several <br /> reasons , including the absence of maps and cross sections depicting <br /> vadose zone contamination. Therefore, GeoAudit submitted additional <br /> information in July 1992, but was unable to respond to all Board <br /> questions without collection of additional data. <br /> GeoAudit submitted a work plan for the installation of additional <br />' soil borings and wells in April 1993 . The objective of this phase <br /> of investigation was to complete the assessment of the lateral and <br /> vertical extent of vadose zone contamination, and to install <br /> remedial wells. One monitoring well, four remediation wells and two <br /> additional soil borings were installed during this phase of the <br /> investigation. The results of the final investigation at the site <br /> 1 <br />
