Groundwater is an important natural resource in Vermont. Vermonters depend on groundwater for their drinking water supply, agriculture, manufacturing and to support aquatic habitat. Groundwater quantity and quality vary with climate, precipitation, overlying land use, and the rock and soil types through which it moves.
Vermont's geology, characterized by deformed (folded, faulted, fractured) rock and a variety of unconsolidated glacial deposits, is the vessel for Vermont's groundwater resources. The Geological Survey maps bedrock and surficial materials, samples water for chemistry as it relates to geologic materials and conducts regional to local studies of groundwater.
Statewide Groundwater Studies: Compilation and assessment of existing datasets, 2010.
County Groundwater Resource Maps were produced at a scale of 1:100,000 based on the statewide analyses.
Town and Watershed Groundwater Projects are conducted in order to understand groundwater sustainability and quality for public and private water supplies.
We use a variety of methods for aquifer characterization.
