Generic ground-water-flow simulation models show that geohydrologic factors-fracture types, fracture geometry, and surficial materials-affect the size, shape, and location of source-water areas for bedrock wells
In this study, conducted by the U.S. Geological Survey in cooperation with the Connecticut Department of Public Health, ground-water flow was simulated to bedrock wells in three settings-on hilltops and hillsides with no surficial aquifer, in a narrow valley with a surficial aquifer, and in a broad valley with a surficial aquifer-to show how different combinations of geohydrologic factors in different topographic settings affect the dimensions and locations of source-water areas in Connecticut.
