WORK PLAN FOR - <br /> C SOIL.AND GROUNDWATER SAMPLING <br /> BY DIRECT PUSH (GEOPROBE) <br /> California State University Stanislaus <br /> Multi-Campus Regional Center <br /> r June 21,2000 <br /> L t <br /> 1. INTRODUCTION <br /> This work plan was prepared by Condor Earth Technologies, Inc. (Condor) to describe soil and <br /> groundwater investigation utilizing Geoprobe direct push technology at the California State University <br /> Stamslaus (CSUS), Multi Campus Regional Center in Stockton, California. The site is located at the <br /> intersection of Aurora Street and Flora Street in the southeast portion of the campus (Figures 1 and 2, <br /> Appendix A). The purpose of the proposed limited subsurface investigation is to evaluate the potential <br /> for petroleum hydrocarbon contamination in soil and/or groundwater related to an underground storage <br /> Ctank (UST) formerly located at the site. -This work plan was prepared at the request of Mr. Mark <br /> Lemieux,Manager of Contract Services for CSUS. <br /> C - <br /> All work conducted by Condor will be under the supervision of a California Registered Geologist. This <br /> work plan includes project background information, a description of the field, laboratory and reporting <br /> procedures proposed to conduct the work, and a project schedule. <br /> 2. PROJECT BACKGROUND <br /> The site contained three USTs associated with past uses of the site. . On July 22, 1998, Henderson <br /> Construction of Stockton, California removed the three USTs from the site, each from a separate <br /> excavation. Tank 6 (TK6) reportedly contained fuel oil for a generator room. Tank 10 (TK10) was- <br /> reportedly a 10,000-gallon capacity UST formerly containing diesel fuel-. Tank 11 (TK11) was <br /> Creportedly a 1,000-gallon capacity UST formerly containing gasoline. TK10 and TK11 were located <br /> adjacent to the north and south end, .respectively, of a fuel dispenser island. TK6 was .located <br /> approximately 100 feet southeast of TKIO and TKI 1. On July 23, 1998, a Condor representative was on <br /> site to collect soil samples under the direction of Ms. Letitia Briggs of the San Joaquin County Public <br /> Health Services Environmental Health Department (PHS/EHD). The.soil samples were analyzed by <br /> APCL of Chico, California. Henderson Construction prepared a brief of letter report, dated August 31, <br /> L �J CONDOR <br /> i' <br />
