New USGS Website Maps Water Quality in U.S. Streams and Rivers

The new USGS National Water Quality Network (NWQN) website provides a map with access to data collected at 110 stream and river sites across the US. Visit the website to access annually updated information on nutrients, sediment, pesticides, and streamflow, including graphs that display how water-quality conditions are changing through time. This data can be useful to local, regional, or national-scale studies related to multiple topics, including drinking water-quality, chemical fate and transport, and harmful algal blooms. For more information and to view the map and data, visit the USGS NWQN website.
