t <br /> �1 <br /> Quik Stop Market No. 132 August 28, 1990 <br /> Job No.349132-31 Page 2 <br /> PROPOSED SCOPE OF WORK <br /> Exceltech proposes to drill and sample five exploratory soil borings at the locations <br /> shown in Figure 2. Three borings will be converted to groundwater monitoring wells <br /> upon their completion. If the results of the groundwater analysis of these wells show <br /> ill install wells where appropriate to fill any <br /> that hydrocarbons are present, Exceltech w <br /> data gap in an attempt to define the extent of contamination. The location of additional <br /> wells, if necessary, will be determined to 1) define lateral contamination with cross- <br /> gradient monitoring wells and 2) define the source of contamination with monitoring <br /> wells downgradient. If further groundwater characterization is necessary, Exc:;ltech <br /> f. <br /> will proceed according to the following flow chart: <br /> � Groundwater Characterization Flow Chart <br /> f a �. <br /> First Question: Has groundwater been impacted? <br /> i � Define soil contamination <br /> Yes I . <br /> Task 1.
