Radon

Radon is a colorless, odorless, and tasteless gas that forms naturally from the radioactive decay of uranium in rocks, surficial materials, and soils over millions of years. After formation, radon can move through fractures and layering in rocks or through connected pores in surficial materials and soils and enter a home through the foundation. Exposure to radon in indoor air is estimated by the Environmental Protection Agency (EPA) to be the second leading cause of lung cancer, with smoking being the first.

Mapping Program

The mapping program produces bedrock and surficial geologic maps by town, quadrangle and watershed. It is funded through STATEMAP, an annual competitive grant process through the National Cooperative Geologic Mapping Program of the U.S.Geological Survey. The State Mapping Advisory Committee, comprised of legislators, consultants, geologists, and mineral industry personnel, meets with the State Geologist to review the map program and make recommendations concerning the goals of this project.

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.
