3 0 CONCLUSIONS, RECOMMENDATIONS AND PROJECT STATUS <br /> Between December 29, 2004 and March 22, 2005, the groundwater surface beneath the site <br /> rose an average of 2 84 feet, the groundwater gradient decreased from 0 0035 to 0 0025 <br /> foot/foot, and the groundwater flow direction remained toward the northwest The groundwater <br /> f flow direction and gradient are consistent with seasonal and historical trends <br /> Between December 29, 2004 and March 22, 2005, the concentrations of petroleum <br /> hydrocarbons detected in groundwater, including TPH-as-diesel, TPH-as-gasoline and BTEX <br /> compounds, generally decreased The oxygenate compounds continued to be below laboratory <br /> detection limits, and 1,2-DCA was detected for the first time in the sample collected from MW-3 <br /> Since the three monitoring wells were installed in December 2000, the concentrations of <br /> petroleum hydrocarbons in groundwater have generally declined, probably in response to source <br /> removal and natural attenuation processes <br /> As shown on Figures 4, 5, and 6, the lateral extent of impacted groundwater at the groundwater <br /> table is undefined for TPH-as-diesel and TPH-as-gasoline, and mostly defined for benzene <br /> Impacted groundwater appears to be concentrated beneath the former USTs, and to the west <br /> and north of the former USTs <br /> On May 8, 2003, Ramage Environmental published Work Plan, Additional Site Investigation and <br /> Groundwater Mon►tonng Report, First Quarter 2003 EHD approved the work plan on June 3, <br /> 2003 Currently, implementation of the approved scope of work is pending the availability of <br /> funding within the county budget <br /> �f <br /> g <br />
