This USGS site provides access to data sets collected by the National Water-Quality Assessment Program. It features fact sheets, reports, bibliographies, additional data sets and links to other resources about nutrients in streams, rivers and aquifers of the United States. The site briefly explains what nutrients are, how they are used in the agricultural industry, how they react chemically in the environment, some of the transport processes that introduce them to surface and groundwater, and why excessive nutrients create water quality problems.
