"NOMA <br /> Working To Restore Nature <br /> GROUNDWATER FLOW DIRECTION <br /> Water level measurements were collected from wells MW-1, MW-2 and MW-3 on March 28, <br /> 1994 Water levels ranged from 27.52 to 27 91 feet below the tops of the well casing <br /> elevations, representing an average rise in the water table of approximately 1 81 feet since <br />' August 1993 The water level data were used to develop the groundwater elevation contour map <br /> (Plate 3) Assuming that horizontal isotropic conditions prevail, groundwater in the uppermost <br /> ' aquifer beneath the site flowed in an east-northeast direction The hydraulic gradient on March <br /> 28, 1994 was calculated to be 0.009 ft/ft or 47 ft/mile A summary of groundwater monitoring <br /> ' data is presented in Table 2 <br /> ' CONCLUSIONS <br /> Petroleum hydrocarbon analytes remained non-detectable in the groundwater sample collected <br /> ' from well MW-1 Concentrations of petroleum hydrocarbon analytes remained the same order <br /> of magnitude or increased slightly in monitoring wells MW-2 and MW-3 since the last <br /> monitoring episode in August 1993 <br />' The direction of groundwater flow has changed and the magnitude of hydraulic gradient has <br /> decreased since August 1993 Groundwater elevations have increased due to seasonal <br /> conditions <br />' RECOMMENDATIONS <br />' Based on the results of the first quarter 1994 monitoring episode, we recommend continued <br /> quarterly monitoring at the site <br /> 1500781QUARTLYIIQR-1994 FNL 3 <br />
