Every five years teams supporting U.S. Environmental Protection Agency’s National Aquatic Resource Survey—consisting of tribal, state, and federal partners—collect samples from over 2000 river and stream reaches throughout the United States. CSS analytical chemists support this effort by processing the samples and then analyzing them for various chemicals to help characterize their water quality.  The data are available at the U.S. EPA National Aquatic Resource Survey website where more information is provided on this program.
