Mr Michael Collins 3 September 17, 1992 <br /> ' PropospQ Well and B rin L.o-cations <br /> Well and boring locations (see Figure 3) were chosen to locate the potential source <br /> area, and to serve as extraction weils, if remediation is necessary Since the results <br /> of the soil vapor survey were inconclusive, the locations are based on results from the <br /> UST removal samples. Because of the sandy soil conditions, extraction wells were <br /> spaced using an assumed radius of influence of 15 feet for vapor extraction, should <br /> it be necessary <br /> ' These locations are only proposed and may be moved based on physical site <br /> characteristics or based on new site information from field activities. Drilling for <br /> Phase II activities is scheduled to start the week of September 28, 1992. <br /> ' If you have any questions concerningthis re lease <br /> report,� p contact Gina Morrison or <br /> myself at (510) 463-9117 <br /> ' Very truly yours, <br /> Chris Young, P E. <br />' Project Engineer <br />' Cy/pm <br /> Attachments <br /> 1 <br /> CanoweEnvlronmental <br /> PL1W 191-63CREPORTS1Colims1 RPT[September 17 19921 <br />
