Simplot Company Facilities <br /> Lathrop, California <br /> On Monday, May 23 , 1988, a WESTON representative (Bruce Handel) <br /> arrived at the Lathrop, J.R. Simplot Company Site to gather soil <br /> samples from beneath two fuel oil storage tanks. These tanks <br /> were being removed. <br /> The WESTON representative arrived at 10:25 am and discussed the <br /> tank removal strategy with Mr. John Pallen (Simplot) and Mr. <br /> Kasey Foley (San Joaquin Local Health District) . The samples <br /> were to be taken from the backhoe bucket. <br /> At 10: 35 am the backhoe bucket was steam cleaned and a backhoe <br /> bucket load of soil was gathered from 3 ' below the bottom of the <br /> diesel storage tank. The sample was obtained from the backhoe <br /> bucket and contained in a brass tube with teflon liners and <br /> plastic end caps. The sample was labeled DST-3 . <br /> At 11: 30 the backhoe bucket was steam cleaned and a bucket load <br /> of soil was gathered from 5 ' beneath the bottom of the gasoline <br /> storage tank. The sample was gathered and contained in a similar <br /> fashion as the diesel tank soil sample. This sample was desig- <br /> nated GST-5. <br /> The samples were stored on ice in an ice chest and transport <br /> directly to the WESTON Analytics Stockton Laboratory. The <br /> samples were to be analyzed for the following parameters: <br /> 0 GST-5 <br /> o BTX- EPA Method 8020 <br /> o TPH - EPA Method 8015 modified <br /> o Organo lead <br /> 0 DST-3 <br /> o BTX - EPA Method 8020 <br /> o TPH - EPA Method 8015 modified. <br /> Attached are the field notes with a field sketch which depicts <br /> the sampling locations and the sampler's field observations. <br />
