NVORK PLAN FOR HYDROCARBON-IMPACTED SOIL REMEDIATION <br /> PROGRESS DRILLING <br /> February 1995 <br /> Art & Artists <br /> 204 East Lodi Avenue <br /> Lodi, California <br /> 1.0. INTRODUCTION <br /> In accordance with the request of Mr. James DeMera of Mullen, Sullivan & Newton, Advanced <br /> GeoEnvironmental, Inc. (AGE) has prepared this Work Plan for soil remediation monitoring at 204 <br /> East Lodi Avenue in Lodi, California (Figure i - Location klap). The scope of work includes the <br /> drilling of up to two soil borings at the site. <br /> The work plan is prepared in accordance with San Joaquin County Public Health Services - <br /> Environmental Health Division (PHS-EIID) and Central Valley Regional Water Quality Control <br /> Board (CVRWQCB) guidelines for the investigation of underground storage tank (UST) sites. <br /> 2.0. BACKGROUND <br /> In July 1994, a Final Remedial Plan (FRP) for the site v,'as prepared by Geological Audit Services, <br /> Inc. (GAS). The FRP recommended installation of a soil vapor extraction/in-situ air sparging <br /> (SVE/IAS) system for hydrocarbon-impacted soil and ground water remediation. The FRP was <br /> approved by the PHS-EHD in August 1994. <br /> In July 1995, an SVE/IAS system was installed inside a fenced enclosure at the southeast corner of <br /> the Art & Artists building. The system began operation in August 1995. Remediation monitoring <br /> recommendations contained in the FRP included the biannual drilling of soil borings and collection <br /> of soil samples to evaluate progress of the SVE system. <br /> 3.0. SCOPE OF WORK <br /> 11. DRILLING AN-D SAMPLING <br /> The scope of work will include the drilling of one or two soil borings within the estimated area of <br /> impacted soil. Estimates are based upon information contained in the Problem Assessment Report <br /> (PAR) and FRP, both prepared by GAS. <br /> Initially, a single boring will be advanced approximately 15 east well MW-1, immediately outside <br /> the fenced enclosure containing the SVE/IAS systems. If hydrocarbon-impacted soil is not <br /> encountered in samples collected from the first boring, a second boring will be advanced <br />
