This data layer was compiled to provide the U.S. Geological Survey's National Water Quality Assessment (NAWQA) Program's study of the Connecticut, Housatonic, and Thames River Basins with digital geologic information that could be applied to the analysis of water-quality characteristics of surface water and shallow ground water. Goals of the NAWQA program are to describe the status and trends of a large representative part of the Nation's surface- and ground-water resources and to identify the natural and human factors that affect the quality of these resources (Leahy and others, 1990). The data set presented here was intended to characterize the bedrock geologic units in the Connecticut, Housatonic, and Thames Basins study area in terms of mineralogic and chemical characteristics relevant to water quality, such that the geologic data exists in digital form and could be used in a Geographic Information System (GIS) to analyze and interpret water-quality and ecosystem conditions.
