About N-Sink

The N-Sink tool was created to be a useful, easy way for local land use managers to explore the relationship between land use and nitrogen pollution in their waters. N-Sink uses the best available science on land use/nitrogen interactions, plus widely available basic datasets for waterway networks, soils and land use, to highlight major sources and sinks of nitrogen within a watershed context.

Sample Watershed Maps

N-Sink is designed as an interactive web tool, but here is a quick look at examples of the three maps created by the N-Sink analysis.  Included here are the Farm River in south-central Connecticut, the Niantic River in southeast Connecticut, and the Palmer River straddling the line between Rhode Island and Massachusetts.
