3.0 CONCLUSIONS, RECOMMENDATIONS AND PROJECT STATUS <br /> Between December 30, 2004 and March 23, 2005, the groundwater surface rose an average of <br /> 1 42 feet, the groundwater gradient increased from 0 0134 to 0 0143 foot/foot, and the <br /> groundwater flow direction remained toward the northeast These groundwater surface <br /> characteristics are consistent with historical and seasonal trends <br /> Between December 30, 2004 and March 23, 2005, gasoline compounds in groundwater generally <br /> increased at MW-1, and remained relatively consistent at MW-2 and MW-3 Concentrations of <br /> gasoline compounds in groundwater at MW-1 have generally declined, since the monitoring wells <br /> were installed in July 2002, probably due to source removal efforts and natural attenuation <br /> processes Since March 2004, concentrations of MTBE have been detected in the perimeter <br /> wells (MW-2 and MW-3) As such, it appears that MTBE has migrated away from the source area <br /> in the downgradient direction, and that the extent of impacted groundwater is undefined <br /> Ramage Environmental recommends that the plume of impacted groundwater continue to be <br /> monitored on a quarterly basis If the concentrations of MTBE in the perimeter wells continue to <br /> increase, it may be necessary to expand the groundwater monitoring well network <br /> 8 <br />
