level indicator. Field procedures for hydraulic conductivity testing are presented in <br /> Appendix E. <br /> The test data were analyzed using the Bouwer-Rice (1989) method to determine hydraulic <br /> conductivity values and compared to published ranges for specific soil types (Freeze and <br /> Cherry,Page 29, Table 2.2). The following information on the recovery testing are included in <br /> Appendix J: <br /> • Aquifer test data sheet <br /> • Analysis work sheet <br /> • Graph of plotted data <br /> • Comparison of calculated hydraulic conductivity values to soil types (Freeze and Cherry, <br /> 1979, page 29) <br /> The relationship between hydraulic conductivity and the average linear horizontal <br /> groundwater flow velocity is defined by Darcy's Law,which can be expressed as follows <br /> (Fetter, C.W., 1988): <br /> v = (K/n)(dh/dl) <br /> where: v =horizontal groundwater flow velocity <br /> K = hydraulic conductivity <br /> n= effective soil porosity (0.35 based on Fetter, 1988) <br /> dh/dl =horizontal hydraulic gradient(0.0006 based on Sept. 3, 1998 event) <br /> 8 <br />
