WORK PLAN FOR <br /> 3 <br /> SOIL AND GROUNDWATER SAMPLING <br /> BY DIRECT PUSH (GEOPROBE) <br /> California State University Stanislaus <br /> Multi-Campus Regional Center <br /> June 21, 2000 <br /> 1. INTRODUCTION <br /> This work plan was prepared by Condor Earth Technologies, Inc. (Condor) to describe soil and <br /> ,. igroundwater investigation utilizing Geoprobe direct push technology at the California State University <br /> Stanislaus (CSUS), Multi-Campus Regional.Center in Stockton, California. The site is located. at the <br /> k 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 I <br /> , <br /> tank (UST) formerly Iocated at the site. This work plan was prepared at the request of Mr.;Mark <br /> Lemieux,Manager of Contract Services for CSUS. <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 /> I . <br /> ' procedures proposed to conduct the work,and a project schedule. <br /> i <br /> a iS <br /> 2. PROJECT BACKGROUND <br /> The site contained three USTs associated with past uses of the site. On July 22, 1998, Henderson <br /> r 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 (TKl1) was <br /> reportedly a 1,000-gallon capacity UST formerly containing gasoline. TKIO and TKl1 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 TK10 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 /> a <br /> Health Services Environmental Health Department (PHS/EHD). The soil samples were analyzed by <br /> APCL of Chico, California. Henderson Construction prepared a brief letter report, dated August 31, <br /> I <br /> 'c <br /> t� ,F CONDOR <br /> �g <br />
