Progress Report:

As of July 2001, six test wells have been constructed and tested to determine aquifer hydraulic characteristics and natural water quality. The wells, located in Shady Side, Deale, Waysons Corner, and Davidsonville, were equipped with continuous water-level recorders to determine the effects that pumping and seasonal fluctuations in recharge have on water levels. Data gathered from the testing were used to construct a three-dimensional ground-water-flow model of the Aquia and Magothy aquifers. The model was calibrated using long-term water-level data and water levels collected from an observation-well network established for the study. Tables, graphs and maps displaying hydrogeologic and model data were prepared.
