Need to reduce loadings of nitrogen and phosphorus in waterways? The U.S. Environmental Protection Agency (EPA) has a tool to help.

The Nitrogen and Phosphorus Pollution Data Access Tool (NPDAT) was created to help states and other stakeholders develop source reduction strategies and numeric criteria for nitrogen and phosphorus, according to EPA’s NPDAT website.

The recently updated tool enables users to view data layered on a map or to download data collected from various EPA data sources, such as SPARROW, the STORage and RETrieval database, the National Water Information System, the National Aquatic Resource Survey, and the National Land Cover Dataset.

Users can find nitrogen and phosphorus loadings in waterways, locate water quality monitoring sites collecting nitrogen and phosphorus data, and see hydrological and political boundaries. New information enables users to find facilities likely to discharge nitrogen and phosphorus to water, waterways listed for nitrogen and phosphorus impairments, and waters with nitrogen and phosphorus total maximum daily loads, the website says.

The tool is one of many technical resources offered on EPA’s Nutrient Pollution website, which provides information, tools, and resources for all audiences.
