EPA researchers develop tool that helps water quality managers meet nutrient load targets

Read the full story from U.S. EPA.

Nutrient pollution is one of America’s most widespread, costly, and challenging environmental problems. This pollution can occur when excess amounts of nutrients, such as nitrogen and phosphorus, run off from land into streams, rivers, lakes, and other water sources. To help water quality managers reduce nutrient pollution, EPA researchers developed the River Basin Export Reduction Optimization Support Tool (RBEROST), a regional online tool currently available for the Upper Connecticut River Basin that provides low-cost solutions to meet nutrient load targets…

RBEROST is publicly available in EPA’s GitHubEXITEXIT EPA WEBSITE online repository. While anyone can use RBEROST, users must have R and RStudio software installed to access the data and code files. Once those are installed, RBEROST will install RShiny through its setup segment, which will allow users to customize management practices and loading targets. RBEROST is also compatible with USGS’ Northeast Regional SPARROW model, which is used to estimate major sources and environmental factors that affect the supply, transport, and fate of contaminants in streams.
