Lauri Cotulla <br /> 30 October 1986 2MIAOSS <br /> ASSOC44M3 PM <br /> 3} Sample soil during well installation in the unsaturated and saturated <br /> zones for chemical analysis: !' <br /> 4) Analyze soil samples for THC and BTXEB by CC/FID. <br /> Y 5) Install two additional ground water monitor wells to determine ground <br /> water gradient and flow direction. it <br /> 6) Develop and sample the three moniJ wells and analyze for THC, BTXEB <br /> and soluble lead. �1 <br /> 7) Prepare a report for regulatory and"comments. <br /> i y review <br /> f ` Our approach is to determine the vertical extent of fuel hydrocarbon <br /> contamination beneath the gasoline tank excavation in the unsaturated and <br /> saturated zones. The three monitor wells will yield data for ground water <br /> f gradient, flow direction and <br /> ground water, quality. If this approach meets <br /> with your approval WA and PI will proceed. 10 fyou have any questions or r <br /> comments please let us know.
