Radioactivity-
Naturally Occuring in Rock, Soil and Water

Compilation and Assessment of
Geophysical and Geological Radioactivity Data in Vermont

The map is a compilation of areas where ground-based and airborne geophysical and geological surveys have indicated the presence of elevated naturally occurring radioactivity relative to surrounding areas. Public water supplies with gross alpha radioactivity equal to or greater than 15 picocuries/liter and uranium occurrences are also shown. Elevated radioactivity areas determined via these surveys in the Milton and Colchester area coincide with many of the locations of domestic groundwater wells with elevated radioactivity. Therefore, the Vermont Geological Survey is showing the statewide distribution of elevated radioactivity areas in Vermont based on an assessment and compilation of data from older sources.
