Letter: Stop nitrogen pollution of waters

Excessive levels of nitrogen from sources, such as wastewater and septic systems, are harming the salt marshes on Long Island, including this one in the Otis Pike Fire Island High Dune Wilderness, seen here on Nov. 10, 2012, that are critical in protecting coastal communities from storm surges and flooding, the state Department of Environmental Conservation has said.

I’m writing in regard to “Private polluters a peril in Suffolk” [News, Dec. 16]. It’s so important to keep our waters clean. Nitrogen is dangerous. Marine life is being harmed, and the groundwater is being threatened.
Our world needs to be protected. The poisoning of our surface waters is a crucial issue, and authorities need to get a handle on it right away. The nitrogen levels need to stop going up.
