Pollutants of Concern in Rockland County’s surface waters (waters ‘above’ such as streams and rivers) are pollutants that may rise to levels high enough to cause a violation with New York’s water quality regulations. When it rains, all the pollutants on the ground are flushed into our waterways through the stormwater. Stormwater runoff is water from rain or even melting snow that runs over the land before it has a chance to soak into the ground, picking up and spreading pollutants. Polluted stormwater runoff is one of the top water quality issues in New York State, as well as a major source of contamination in the Nation’s waterbodies that ultimately pollutes our drinking water sources. One goal of the State’s stormwater program is to implement no net increase of Pollutants of Concern in our waterways. Our everyday activities contribute to POCs, which include pathogens from trash and leaky septic systems, drippy motor oil from our vehicles, and nutrients that lead to excessive algae growth (“scum”) and fish die-offs. See our Nutrient Pollution brochure for common POCs and ways you can reduce them (‘Your Home & Water Quality Impacts at http://rocklandcce.org/fact-sheets.
(Note on side of photo): When it rains, stormwater runoff rapidly carries pollutants over the land within your watershed, such as salt from roadways, motor oil from our vehicles, fertilizers on our lawns, animal wastes and more. This runoff flushes to local waterbodies causing great impacts to them and to the final receiving water in your watershed. If you see a construction site with sediment leaving the site or draining to the catch basin which will also cause clogging, report this at once to your municipality .
