Arsenic in Vermont’s Groundwater Resource and the Connection between Geology and Public Health

Arsenic is a naturally occurring trace element in the natural environment, and in some regions geological factors have conspired to create elevated arsenic concentrations in the rocks and sediments that host groundwater. Research over the past ten years by the Vermont Geological Survey, the Vermont Department of Health and Middlebury College has revealed that certain parts of the state are prone to elevated arsenic in bedrock aquifers – these include parts of the Taconic slate region, the Rowe-Hawley Belt in north-central Vermont and parts of Windsor County in the vicinity of a granitic intrusion. This talk will explore geological, topographic and hydrological controls on groundwater arsenic in the complex geological landscape of Vermont and also reflect on recent changes to public policy as a result of scientific research.
