Coca-Cola Enterprises - West <br /> Job No. 90054 <br /> s <br /> Two steel underground storage tanks (USTs) existed at the site; one 10,000-gallon diesel UST <br /> T and one 1,000-gallon gasoline USI'. The diesel UST was installed in 1978 and the gasoline <br /> UST was installed in 1937. The site conditions at the time of USTEC's investigation including <br /> the location of the buildings, the former USTs, and soil gas sampling points are presented <br /> " on Figure 2- <br /> 1.2 <br /> 1.2 SCOPE OF WORK <br /> r; The preliminary field investigation was conducted during May 9 and 10, 1990. Work <br /> consisted of a soil gas survey designed to astimate the lateral extent of petroleum <br /> hydrocarbon contamination found during tank removal operations at the site. The soil gas <br /> survey will be used as a basis for the location o: future groundwater monitoring wells and <br /> soil borings. <br /> The soil gas survey consisted of twenty-two soil gas point locations. Of the twenty-two. <br /> point locations, two points, SG-3 and SG-12.were tested at multiple depths (5 and 13 feet). <br /> All other soil gas samples were collected at a depth of 5-feet. The Iocation of these samples <br /> is shown on Figure 2 <br /> k, All soil gas samples were analyzed for volatile organic compounds including benzene, <br /> toluene, and total xylenes, (BTX). In addition,a total volatile petroleum hydrocarbon (TVPH) <br /> analysis was provided for each sample. <br /> 2.0 FIELD METHODS <br /> The field investigation consisted of a soil gas survey which includes soil gas sampling and <br /> analytical testing. The soil gas survey was completed by Optimal Technology Inc., <br /> Carpinteria, California, under the supervision of a USTEC representative. <br /> �: 2 <br />
