Vermont's geology contributes to many facets of human health. Bedrock, glacial materials, and soils each have positive and/or negative impacts on water quality and air quality. Healthy human bodies require minerals and elements (ex. salt, calcium, iron) which are transferred from the geologic environment through the food chain. Some geologic materials may filter contaminants so they do not reach groundwater supplies. Geologic materials may also be the source of airborne contaminants or of naturally-occurring elements of concern in drinking water, including radionuclides and arsenic.
The Geological Survey and our partners work on geology and health issues related to arsenic, radionuclides, radon, nitrates, floride, manganese , asbestos and other contaminants. The investigations focus on source, fate and transport of materials within earth systems and the impact on both human and environmental health. The goal is to reduce exposure of Vermonters to chemical and mineral contaminants. View list of current projects and our process for aquifer characterization.
