Curbing Polluted
Stormwater Runoff

What is Polluted Runoff?

Did you know that the way we care for our homes, lawns, cars, and streets says a lot about how much we care about the health of Long Island Sound? That’s because commonly-used products such as fertilizers, pesticides, household cleaners, and motor oil can pollute Long Island Sound if we fail to use and dispose of them properly. How so? Rain or melted snow can carry products such as fertilizer, pesticides, or leaking motor oil from driveways, streets, and lawns into local streams or storm sewer systems. Eventually, these harmful chemicals get flushed into the Sound.

Why Should We Be Concerned?

Here are a few reasons:

  • The oil from a single automobile engine can produce an eight-acre oil slick;
  • The fertilizer that helps keep lawns and plants abundant can fuel the excessive growth of algae when it reaches a water body, which then sucks up the oxygen needed for fish and other animals living in the Sound;
  • And the soil washed into the Sound can harm fish eggs and clog up harbors.
