GROUNDWATER

Groundwater is an important natural resource in Vermont. Vermont’s population depends on groundwater for their drinking water supply. Groundwater is also used for manufacturing, agriculture, commercial enterprises, and to support aquatic habitat (“The Status of Groundwater and Aquifer Mapping in Vermont, January 2003” (pdf)). Groundwater is dynamic, responding to internal and external conditions. Groundwater quantity and quality varies with climate, precipitation, overlying land use, and the rock and soil types through which it moves. Vermont's geology, characterized by multiply deformed (folded, faulted, fractured) rock and a variety of unconsolidated glacial deposits, is the vessel for Vermont’s groundwater resources. The Survey focuses on mapping bedrock and surficial deposits and obtaining data about this vessel.

Statewide Analyses of Groundwater

Statewide maps (2009, 2010).
The Vermont Geological Survey compiled and assessed existing datasets (bedrock and surficial maps plus water well, soils and elevation data) related to groundwater in Vermont. Groundwater favorability maps for aquifers in surficial materials are in progress.

Groundwater poster presented at NEGSA, 2014: A GIS-based approach to characterizing Vermont's groundwater resources by M. Gale, G. Springston, J. Van Hoesen and L. Becker.

Water well interference study (Vt Rural Water, 2009): Part 1, 2, 3, 4, 5

A water use study by Medalie and Horn, 2010, Estimated Water Withdrawals and Return Flows in Vermont in 2005 and 2020: USGS study which identifies areas of increased groundwater use. Contact the Vermont Geological Survey for a copy of the database.
Also see the USGS Water Use web page

County Groundwater Resource Maps : As part of the statewide analysis of groundwater resources, the VGS is producing county maps at a scale of 1:100,000.
