Groundwater Quality in Selected Stream-Valley Aquifers, Eastern United States

Fact Sheet 2022-3037
National Water Quality Program
National Water-Quality Assessment Project



Groundwater provides nearly 50 percent of the Nation’s drinking water. To help protect this vital resource, the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Project assesses groundwater quality in aquifers that are important sources of drinking water (Burow and Belitz, 2014). The stream-valley aquifers constitute one of the important aquifer systems being evaluated.
