Groundwater Studies

PLAN - MAP - TEST - PROTECT
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.

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.

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.
