HydroGeo Consultants <br /> Analysis of drawdown data for observation wells MW-4, TB-1, and TB-7 is summarized <br /> in the following Table 2 According to Todd (1980), hydraulic conductivities in this <br /> range are representative of soils consisting of medium grained sand to coarse grained , <br /> sand These soils are slightly coarser grained than those described in the boring logs for <br /> the Site <br /> Table 2 ' <br /> Observation Well Results (Time Drawdown) <br /> Aquifer Parameters MW-4 TB-1 TB-7 <br /> Transmissivity(ft2/day) 3191 2260 1507 r <br /> ds = 0017 ds =0024 ds = 0036 <br /> Hydraulic Conductivity (ft/day) 80 57 38 <br /> Storativity (dimensionless) 0 059 NA NA <br /> Groundwater Velocity (ft/day) 1 7 12 082 <br /> Distance drawdown was also analyzed for the seven observation wells by plotting the <br /> maximum drawdown observed in each well and the distance each well is from the <br /> pumping well (Figure 10) This data was also analyzed and the results are included in <br /> Table 3 below According to Todd (1980), hydraulic conductivities in this range are ' <br /> representative of soils consisting of fine grained sand, and appear to be moderately <br /> representative of described Site soils <br /> Table 3 f <br /> Observation Well Results (Distance Drawdown) <br /> Aquifer Parameters Pumping ' <br /> Transmissivity (W/day) 362 <br /> ds= 015 <br /> Hydraulic Conductivity (ft/day) 9 1 ' <br /> Groundwater Velocity (ft/day) 020 <br /> Stagnation Point (ft) (ro) 240 <br /> 1 <br /> Page 10 TOC#171 Aquifer Test and RAP Rpt ' <br />
