Monitoring Groundwater Levels and Maintaining Databases

Long-term measurement of groundwater levels throughout the Virginia Eastern Shore aquifer system continues to be an important aspect of understanding spatial and temporal changes in groundwater resources. Well maintenance and data collection and management are accomplished cooperatively by the Virginia Department of Environmental Quality and USGS.

In cooperation with USGS, the Virginia Department of Environmental Quality currently measures groundwater levels in 66 wells in Accomack and Northampton Counties of Virginia. Measurements include near real-time water levels, collected at intervals of an hour or less, and field measurements of water levels, collected at intervals of weeks to months.

Thousands of historical measurements at these and other wells also have been recorded. All water-level measurements are maintained in USGS databases and are available to the public through the National Water Information System.

Two web tools are available for exploring the Virginia Eastern Shore groundwater well monitoring networks and accessing data:
