Le � 5.2 Ground Water Gradient A ground water gradient map was produced from the data obtained from the June 22, r� 1995 sampling event (Figure 2). The ground water gradient betwwen M.W-2 and MW-6 is calculated to be 0.004 ft/ft. The ground water flow direction is toward the west during this sampling event. This gradient and flow direction is consistent with previous monitoring events. TABLE 4 L" Monitoring Well Water Elevations r L.

Gasoline levels of 26 mg/L and 0.76 mg/L were found in wells MW-1 and MW-6, respectively. The duplicate sample analysis performed on the MW-6 sample indicated L- slightly higher levels, however, they are within acceptable ranges to verify the accuracy of the primary sample. The bailer blank collected at MW-1 indicated non detectable levels for all analyzed constituents. The remaining four monitoring wells, MW-2, MW-3, MW-4 and MW-5 all indicated non LO detectable levels for gasoline and gasoline constituents during this quarter. Ground water samples were analyzed for dissolved lead and chromium from each of the six monitoring wells, one bailer blank collected at MW-1, and one duplicate sample collected at MW-6. Laboratory analyses indicate non detectable levels for dissolved lead in all of the samples analyzed. Dissolved chromium was detected in monitoring wells Le MW-2, MW-3, MW-4 and MW-5 at levels below the maximum contaminant level (MCL) of 0.10 mg/L. American Geological Services, Inc. cA95DE-029 9 L..
