The Report discusses the results of 10 direct push borings to <br /> collect grab groundwater samples and the installation of monitoring well MW-35. Although <br /> MW-35 was installed downgradient of borings with no or low detections of constituents of <br /> concern, the sample from MW-35 has detections of total petroleum hydrocarbons as gasoline and <br /> diesel, tertiary butyl alcohol, and di-isopropyl ether. Shell recommends sampling MW-35 for <br /> four quarters to determine if additional monitoring wells are needed. <br /> Regional Board staff concurs with the recommendations in the Report. In the 2003 Annual <br /> Report, due 30 January 2004, Shell needs to include a discussion of the extent of petroleum <br /> pollution, the effects of the groundwater pump and treat system on the extent of the plume, and <br /> whether additional monitoring wells are needed.
