This report describes the ground-water system and presents results of numerical simulation of ground-water flow in the area of the North Penn Area 6 site, Lansdale, Pa. All hydrologic and geologic data collected by USGS during the 3-year (1996-99) investigation in and near Lansdale are summarized in this report; these data include geophysical logs and measurements of stream base flow, water levels in wells, chemical and physical properties of ground-water samples, and responses of water levels in wells to aquifer tests. Aquifer characteristics are defined. Ground-water flow directions, capture zones for streams and wells, and flowpaths from known sources of contamination in soil are presented for simulations under three different pumping conditions.
