Rappahannock River The ability of groundwater resources to meet the needs of Fauquier County over time, in terms of both water quantity and water quality, is unknown. Considerable work is needed and is on-going to help us understand this resource and to plan for the future.   

Presentations at the Conservation Roundtable, July 31, 2017

County residents outside of the Town of Warrenton rely exclusively on groundwater for their water supply needs. In decades past, the County explored surface water options including reservoirs, and due to high costs, impacts on historic and environmental resources, and public opposition, the Board of Supervisors abandoned the idea in favor of groundwater.

Over the past 20 years or so, the County, in conjunction with the Water and Sanitation Authority, has undertaken numerous investigations and projects focused on building water supply capacity within Service Districts. Additional approaches to monitor and protect our groundwater resources are needed to ensure a quality water supply for future generations.
