Water Questions
Where Does Our Water Come From?
The water that flows from every single spigot in Nassau and Suffolk County comes from groundwater aquifers and nowhere else.
Where Does It Go When I Flush?
Even when working properly, traditional Long Island cesspools and septic systems are not designed to keep reactive nitrogen from entering groundwater aquifers.
What is Nitrogen Pollution?
Nitrogen makes plants grow. But too much of a good thing is a bad thing. When too much nitrogen flows to our bays, fast-growing plants out-compete and kill slower-growing beneficial plants.
