3.0 CONCLUSIONS, RECOMMENDATIONS AND PROJECT STATUS <br /> Between September 12, and December 11, 2003, the groundwater surface dropped an average <br />' of 0 08 feet, the groundwater gradient increased slightly from 0 0113 to 0 0114 foottfoot, and the <br /> groundwater flow direction remained consistent toward the northeast The depth to groundwater <br /> beneath the site was at its lowest level, since the monitoring wells were installed in July 2002 <br /> Otherwise, the groundwater surface characteristics are consistent with historical trends <br /> Between September 12, and December 11, 2003, gasoline compounds in groundwater continued <br /> to be limited to MW-1, and in close proximity to the former UST During the quarter, the <br /> concentrations of gasoline compounds at MW-1 remained relatively stable Concentrations of <br /> gasoline compounds in groundwater have generally declined, since the monitoring wells were <br /> installed in July 2002, probably due to source removal efforts and natural attenuation processes <br /> The extent of impacted groundwater appears to be defined to the north by MW-2, and to the <br /> northeast (downgradient) by MW-3 <br /> To date, the source of gasoline has been removed, the downgradient extent of the plume of <br /> impacted groundwater has been defined, and concentrations of gasoline compounds in <br /> groundwater appear to be degrading No sensitive receptors appear to be threatened by the <br /> gasoline compounds in soil and groundwater beneath the site Based on these conditions, <br /> Ramage Environmental recommends that EHD and RWQCB consider the case for regulatory <br /> closure In the meantime, the three monitoring wells should continue to be monitored and <br /> sampled on a quarterly basis The next monitoring event is scheduled for March 2004 <br /> 7 <br />
