The last step is the confirmation stage to <br /> optimize the design and operation of the wells for the <br /> E~' management and remediation of <br /> ground water. <br /> This section presents the results and findings of the aquifer <br /> ry analysis and tests performed to date. <br /> LB <br /> v' w <br /> ` The hydraulic Y properties of aquifers and soil materials that <br /> define the rate of water movement it <br /> subsurface materials, and its effect o, <br /> then ie and out of zometric <br /> E? surfaces or water tables, are hydraulic conductivity <br /> (K <br /> transmissivity (T) , and storage coefficient (S) or specific <br /> yield for unconfined aquifer. <br /> Hydraulic conductivity is defined as the rate at which water <br /> moves through a porous media (soil) under a unit hydraulic <br /> gradient. It is primarily dependent upon the porosity and <br /> permeability of the soil and the density and viscosity of the <br /> 6.; water. However, not all water occupying pore spaces in .a <br /> saturated aquifer can be readily extracted. one measure of <br /> [ the water-yielding ability of an aquifer is the storage <br /> coefficient.
