The document is the result of an initiative to design and mathematically model a ground-water withdrawal system that would increase well yields at two Superfund sites with contaminated coastal aquifers, without inducing the movement of saltwater up into the freshwater zone of the aquifer. Implementing the model equation before initiating a pump-and-treat effort or operating a freshwater production well should roughly predict how a coastal aquifer will liekly behave under new stress conditions imposed by the operation of a pumping system on the aquifer. The equation is fairly simple and easily implemented on a computer. The operation of a multilevel pumping-well system has been shown to be effective in improving overall well yields.
