Summary
Abstract: Leakance, which is the vertical hydraulic conductivity of the confining unit divided by its thickness, can be used to provide an indication of the degree of confinement of the aquifer. For purposes of this discussion, an aquifer is considered to be well confined, or have 'good confinement', if leakance was less than 1.0 x 10-3 1/d. Sites where leakance was determined by aquifer testing to be less ... View entire text
