' k'q KLEINFELDER <br /> was analyzed for the first time in January 2001 and was detected in the groundwater sample <br /> collected from MW-1 at 3 3 mg/1 <br /> 1 Based upon analytical data obtained during these sampling events, the CVRW CB and EHD <br /> requested continued quarterly groundwater sampling, and preparation of a workplan to address the <br />' extent of the contamination in the vicinity of the subject site, including a sensitive receptor survey <br /> and estimates as to the amount of contarmnatzon in soil and groundwater <br /> At the request of General Mills, Kleinfelder installed three additional monitoring wells in the <br /> vicinity of the UST in January 2002 (MW2, MW-3 and MW4) During the installation, soil <br /> samples were collected from the bonngs and submitted for laboratory analysis None of these <br /> samples contained detectable concentrations of TPH-G, TPH-D, nor BTEX, at or above laboratory <br /> reporting limits <br />' Four quarterly sampling events were conducted in 2002 with groundwater samples collected from <br /> all four monitoring wells MW-i through MW-4 Monitoring wells MW-2, MW-3 and MW-4 were <br />' installed as perimeter monitoring wells MW-2 and MW-3 were installed downgradaent of the UST <br /> area and MW-1 was installed upgradient of the UST area Based on findings of the four quarterly <br /> sampling events conducted during 2002, fuel constituents continued to be present in MW-1 <br />' including TPH-D, TPH-G, ethylbenzene and total xylenes at relatively lower concentrations (See <br /> Table 2) Floating product was noted in September 2002 in monitoring well MW-1 Product <br /> thickness since this time has been noted in MW-1 at thicknesses ranging from a film (<0 1 feet) to <br /> approximately 4 inches A trace concentration of TPH-D was detected to the June 2002 sampling <br /> event in downgradient well MW-2, followed by four quarterly sampling events of non detect results <br /> for the requested petroleum constituents <br />' The following Sections document Kleinfelder's findings from the four <br /> th quarter 2003 sampling <br />' event <br /> 1 <br /> 1 <br />' 28209 T03/ST04R]57 <br /> Page 5 of I 1 <br />' OO 2004 Klemfelder, Inc February 3,2004 <br />
