QUOGUE - Fifteen bodies of water on Long Island have been added to New York's list of "impaired waterways," and Long Islanders who make their living on the water say something has to be done to preserve water quality.

Environmentalists say the cause of the pollution involves nitrogen that leaks into the water from sewage treatment plans and underground cesspools. Ed Warner, a bayman and trustee for the Town of Southampton, says the nitrogen is killing fish.

"I make my living on the water. I'm out there every day and see what's going on," says Warner. Baykeepers suggest de-nitrification technology be implemented to save the water.

Out of the 15 bodies of water added to the list, nine are in Suffolk County and six are in Nassau County.
