SINCLAIR TRUCKING <br /> Page 2 <br /> Boreholes completed as MW-1 and MW-4 confirm the presence of fuel hydrocarbons 'in soil above and <br /> beneath observed groundwater levels. Concentrations of TPH as gasoline and. Benzene are confirmed at 14 <br /> feet below grade surface in borehole MW-4 7 930 <br /> . ( -mg/kg :and I 1• mg/kg respectively), Higher <br /> concentrations of TPH as gasoline and Benzene are confirmed at 9 feet below grade surface in borehole <br /> MW-I (13,600 mg/kg and 171 mg/kg respectively).,,Borehole MW-4 is approximately 30 feet from MW-I, <br /> the concentrations of fuel hydrocarbons at these points suggest that hydrocarbon contamination is present <br /> laterally between and beyond these data points. Please complete the definition of the soil and groundwater <br /> plume. IIs <br /> 1 <br /> You are directed to submit a workplan to PHS/EHD which when implemented will define the'soil <br /> and groundwater plume at this site. The workplan must be received at PHS/EHD offices no later <br /> than 5:OOpm on September 15, 1999. l <br /> PHS/EHD strongly recommends that the responsible party at this.site routinely request at least three bids <br /> for all scopes of work proposed related to corrective action activities at this Underground Storage Tank site. f <br /> All site work must be approved by PHS/EHD first then cost pre-approved by the Underground Storage <br /> Tank Cleanup Fund(USTCF)prior to commencing work. ` <br /> f <br /> Should you have questions.regarding this correspondence please contact Ron Rowe at (209) 468-0342 or 1 <br /> Margaret Lagorio at(209)468-3449, } <br /> Donna Heran, REHS,Director <br /> Environmental Health Division <br /> Le <br /> Ronald Rowe, Sr. REHS Margaret agorio, RENS i <br /> LOP/Site Mitigation Unit Supervisor <br />
