What's in the Water?
Interested in water-quality concentrations, loads, and trends in streams and rivers across the United States? Check out a new USGS website with data from the USGS National Water Quality Network—110 stream and river sites with long-term, consistent data on water quality.
Use the website to access annually updated information on nutrients, sediment, pesticides, and streamflow. These data are collected to assess the status and trends of water-quality conditions at large inland and coastal river sites as well as in small streams in urban, agricultural, and undeveloped basins.
