J. H. KLEINFELDER & ASSOCIATES <br />File No. S-1716-2 <br />July 2, 1985 <br />Page 6 <br />sampling techniques employed in the field. <br />Each well head will be surveyed in and sounded to determine the pieziometric <br />water level in each well and to determine the general groundwater gradient underlying <br />the facility. Analytical results and the groundwater gradient will be used to <br />recommend the location of additional wells. <br />Disposal method of the purge water must be approved by the county and state. <br />Options include storm sewer discharge or temporary containerization for eventual <br />treatment in conjunction with the groundwater remedial program. We will investigate <br />these options and recommend the most cost-effective option prior to well development. <br />P hase 2 <br />Phase 2 is intended <br />to refine the Phase 1 data by establishing <br />groundwater <br />contours and obtaining additional data to <br />assess the extent of the <br />groundwater <br />contamination. We will locate and install a <br />well in the most upgradient <br />location to <br />establish upgradient water <br />quality conditions. <br />Approximately three additional wells may <br />be installed downgradient <br />of identified sources to describe the contaminant <br />plume. <br />Construction sampling and <br />analyses of these <br />wells will follow the program <br />outlined for <br />Phase 1. <br />Phase 3 <br />Phase 3 work will be necessary only if the wells installed in Phases 1 and 2 <br />cannot sufficiently establish the leading edge of the contaminant plume. We estimate <br />that one of two additional wells could be necessary in this phase. <br />REPORT OF FINDINGS AND EVALUATION OF REMEDIAL ALTERNATES <br />A report will be prepared summarizing the findings of the investigation.
