Land use planners, property owners, and watershed managers need all the help that they can get to reduce the impacts of nitrogen (N) pollution on waterways, particularly in coastal areas. CLEAR, URI and EPA have developed an online tool, N-Sink, that provides some of this help. N-Sink identifies areas within a watershed that are likely to contribute N to coastal waters, and other areas that are likely to remove N from the system before it gets to the coast. The tool now covers all of the coastal watersheds of Connecticut and Rhode Island. This 30-minute webinar will describe the workings behind the tool, demonstrate the new N-Sink web app, and initiate a discussion on ways that the information might be used. Presented by Chet Arnold & Qian (Rachel) Lei-Parent, UConn CLEAR on 4/21/21.
