National Water Quality Assessment (NAWQA) Program

The National Water Quality Assessment (NAWQA) Program is a research initiative by the U.S. Geological Survey that studies the quality of water sources like rivers, lakes, and groundwater across the country. Its goal is to understand what pollutants are present, how water quality changes over time, and what factors influence these changes. The program provides valuable information to help communities manage water resources, protect public health, and ensure safe water for everyday use and ecosystems. NAWQA combines scientific monitoring, data analysis, and reporting to support informed decision-making.
