3.0 CONCLUSIONS, RECOMMENDATIONS AND PROJECT STATUS <br /> Between August 23, and December 30, 2004, the groundwater surface dropped an average of <br /> 0 37 feet, the groundwater gradient decreased from 0 0022 to 0 0016 foot/foot, and the general <br /> direction of groundwater flow remained toward the east The groundwater surface configuration <br /> appears to be consistent with historical and seasonal trends <br /> Between August 23, and December 30, 2004, the concentrations of gasoline compounds in <br /> groundwater remained relatively stable Gasoline hydrocarbons are concentrated as free product <br /> near former UST#3, and concentrations of gasoline compounds decrease with distance from the <br /> source area As shown on the isoconcentration maps, the lateral extent of MTBE in groundwater <br /> is mostly defined (Figure 7), and the lateral extents of TPH-as-gasoline and benzene in <br /> groundwater remain undefined to the west of the source area (Figures 5 and 6) The vertical <br /> extent of impacted groundwater has not been investigated <br /> Between October 5, and December 13, 2004, the thickness of free product in MW-1 decreased <br /> significantly During the fourth quarter of 2004, approximately 112 25 ounces of free product were <br /> removed from MW-1 in three monthly site visits <br /> Between February 23 and 25, 2005, Ramage Environmental supervised the installation of one <br /> nested sod vapor extraction well, one nested air sparge/soil vapor extraction well, and one <br /> additional groundwater table monitoring well The results of this work will be submitted with the <br /> first quarter 2005 groundwater monitoring report <br /> Ramage Environmental recommends ends that upon the availability of funding, the previously-approved <br />' remedial feasibility testing tasks be completed In the meantime, monthly free product removal <br /> and quarterly groundwater monitoring should continue <br /> i <br /> 1 <br /> 1_ <br />
