National Water Quality Assessment (NAWQA)

The National Water Quality Assessment (NAWQA) is a program by the U.S. Geological Survey that studies the quality of the nation's rivers, lakes, and groundwater. It aims to understand the health of these water sources by monitoring pollutants, patterns, and changes over time. NAWQA collects data to inform policymakers, scientists, and the public about water quality issues, helping to protect drinking water and aquatic ecosystems. By assessing trends and identifying sources of contamination, the program plays a crucial role in ensuring safe and clean water for communities across the United States.
