Central Valley Water Board staff requested the <br /> Work Plan in our 12 May 2009 letter and discussed the work with KMEP during a <br /> 17 June 2009 meeting. <br /> Our 12 May letter observed that none of KMEP's monitoring wells are screened in the C or D <br /> zones and therefore provide no vertical delineation of the groundwater pollution. Central Valley <br /> Water Board staff requested a meeting to discuss additional investigation to address this data <br /> gap. During the meeting, KMEP concurred that the plume at the Site is not vertically <br /> delineated and agreed to prepare a work plan for one deep boring. <br /> Groundwater bearing zones underlying the Site are divided into four progressively deeper units <br /> designated as the A, B, C, and D zones. The Work Plan proposes to install two monitoring <br /> wells; one in the B zone and one in the C zone in the vicinity of SP/M-9 at total depths of <br /> 30 and 60 feet below ground surface (bgs), respectively. SP/M-9 is closest to KMEP's <br /> manifold area, the acknowledged source area for petroleum hydrocarbons that emanate from <br /> the KMEP facility. KMEP's wells, including the proposed wells, are located on property leased <br /> by another petroleum company. There are two monitoring wells at the facility, SP/M-7 and <br /> SP/M-8, that have screens that extend into the B zone. These wells, however, are located <br /> about 100 feet to the west and east of monitoring well SP/M-9. <br /> The proposed wells will be developed and sampled about 24 hours following installation. <br /> Performance of the field work will be contingent on obtaining access agreements with the <br /> property owner, the Port of Stockton. <br /> CaliJornin Environmental Protection Agency <br /> 0 Recycled Paper <br />
