The values used to solve the above equation are as follows: <br /> K = 8.11 x 10-5 centimeters per second (cm/sec) or <br /> 83,69 feet per year (ft/yr) <br /> i = 0.0106 foot per foot (ft/ft) for northwest flow between SB-1 and <br /> MW-5 <br /> = 0.0003 ft/ft for northwest flow between MW-4 and SB-1 <br /> n = 0.30 <br /> The hydraulic conductivity deten-nined with a slug test in well MW-4 was <br /> 8.11 x 10-5 cm/sec for the perched groundwater zone.The hydraulic gradients were <br /> calculated by dividing the difference in groundwater elevations between contour <br /> lines 234 and 229 for the northwesterly flow between SB-1 and MW-5 and water <br /> elevations recorded in wells MW-4 and SB-1 for the northwesterly flow between <br /> MW-4 and SB-1 by the distance between contour lines measured in the direction <br /> of groundwater flow. <br /> An average porosity value of 0.30 was used based on published porosity values <br /> for similar geologic materials. <br /> A maximum groundwater velocity of 2.97 ft/yr was calculated for the <br /> northwesterly flow as follows: <br /> V = 83.69 fflyr x 0.0106 ft/yr <br /> 0.30 <br /> 2.97 ft/yr <br /> A maximum groundwater velocity of 0.08 ft/yr was calculated for the <br /> northwesterly flow as follows: <br /> V = 83.69 ft/yr x 0.0003 ft/yr <br /> 0.30 <br /> 0.08ftlyr <br /> Stephen T.
