USGS National Water Quality Network

Understanding the quality of U.S. streams, rivers, and groundwater requires consistent data collection and analysis over decades for proper context of current conditions. The USGS collects nationally standardized data and information as part of the National Water Quality Network (NWQN). The NQWN is made up of sites across the Nation where USGS scientists regularly measure water-quality conditions.
