An <br /> additional nmahoring wan west of MW-14, likely to be off-site, <br /> Js needed to (Wly denm the extent of the hydrocarbon plume. <br /> Will eoc Uedon wean recover ground Water tear MW-14? <br /> Leprino Response: As stated in tate previous comment response, three additional <br /> monitoring wells are proposedfor installation Off-site to fully <br /> delineate the extent of the plume. Leprino proposes to place one <br /> of these monhoring welly northwest of MW-14 on the opposite <br /> side of the maWead right-of-way. The proposed locations for all <br /> three Monitoring wells are provided in the report titled "Second <br /> Qusrw orouud Water Sampling sed Analysis" (Hydro-Search, <br /> Inc. 1995). <br /> The intent of the exttaciion system is to provide complete <br /> containment across the entire site and prevent any uff-site <br /> migration of dee dissolved and fns-product plume. Ile system <br /> will also be designed to recover portions of the dissolved-plume <br /> which may have potcntlally migrated off-site. Although <br /> extractions wells are currently not planned for installation near <br /> MW-14, an extMcdoo well is proposed to be installed directly <br /> downgradient. Gnouadwater ntrttr MW-14 will thc.-eby be directed <br /> toward the dowagradient extraction well once the system becomes <br /> operational. <br /> If you have any additional questions regarding the KAP,please do not hesitate to contact me at <br /> any time. <br /> Sincerely, <br /> John Ewing, P_P.. <br /> LF-PRINO FOODS, INC. <br /> cc: Roy Gremgrass, Lepdno Ponds, Inc. <br /> Chris Williams, Hydro-Search, Inc. <br />
