The U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Program will characterize the status and trends of water quality and aquatic ecosystems by monitoring ambient water-quality and ecological conditions through a National Fixed Site Network (NFSN).The NFSN includes 102 surface-water stream and river sites across the United States. This annual water-quality reporting Web site is the primary vehicle for the reporting of NFSN data and findings.
