Coastal Plain Groundwater

The coastal plain region of the Potomac River basin includes portions of the states of Maryland and Virginia, and parts of Washington, D.C. The principal sources of water in this region are confined aquifers, although a shallow unconfined system is sometimes used as well, particularly for domestic supply wells. Regions of high water use are impacting groundwater heads. Additional information on the extent of the drawdown as well as the implications for water supply is needed.

On June 14, 2005, ICPRB hosted a meeting of regulators (Maryland Department of the Environment, Virginia Department of Environmental Quality, D.C. Department of Health) and scientists (Maryland Geological Survey, USGS - MD-DE-DC office and VA office) to share information on the coastal plain groundwater system and to discuss common issues of concern. Managing the water supply to ensure its sustainability for future generations is a common concern of all the jurisdictions. Working together to better understand this shared resource can help to achieve management goals.

On March 9 2006, ICPRB hosted a meeting of regulators, local water supply planners and managers, and scientists, with presenters from Maryland Department of the Environment, Virginia Department of Environmental Quality, Maryland Geological Survey, and USGS - MD-DE-DC office and VA office to share information on the coastal plain groundwater system and to discuss common issues of concern. Download the program. Presentations will be available soon. A list of key issues were developed from the meeting's discussions. Several presentations from the workshop are available:
