• The depth to groundwater in the three monitoring wells was measured with a Solinst water level <br /> meter, and a battery-operated purge pump was used to purge the wells of standing water. Fifty-five <br /> gallons of water were removed from the wells and stored in a DOT-approved drum on site. After <br /> purging, water samples were collected in glass vials and transported to the laboratory. <br /> In contrast to previous quarters, the present groundwater gradient is southwest, at 0.025 ft/ft. The <br /> reason for the 180-degree reversal is unknown. Hydrocarbons were detected in all wells, but at <br /> significantly lower concentrations than in previous events. The reason for this decrease is uncertain, <br /> but could be due to either a seven-foot rise in the water table or the change in groundwater flow <br /> direction. It is unlikely that the decrease represents a real change in contaminant concentrations. <br /> • <br /> 2 <br />
