The US Environmental Protection Agency Office of Water is rolling out several new tools to help fight “nutrient pollution” (high loadings of nitrogen and phosphorus) into our waters. Their redesigned Nitrogen and Phosphorus web site (http://www.epa.gov/waterscience/criteria/nutrient/) now houses scientific literature reviews, monitoring data, guidance manuals, and Web casts to help states establish numeric water quality criteria for nitrogen and phosphorus. The new web site also offers answers to states’ questions about how to use the criteria and a clearinghouse of water treatment technologies and land-use practices. The public can also visit the web site to learn more about this environmental problem and find out what each of us can do about it.
