Long Island waters threatened by excess nitrogen

As the weather starts to heat up, Long Islanders headed to local beaches may have to share the water with an unwanted visitor: toxic algae.

Last year, toxic algae was found in nearly every major bay and estuary across Long Island, according to data compiled by the Nature Conservancy, a national environmental organization. 

President of Friends of Bellport Bay, Thomas Schultz, explained that the excess algae blocks sunlight from penetrating the water column, thereby inhibiting photosynthesis. “We do have some bodies of water like that where there’s hardly any life at all because there’s no oxygen, there’s no photosynthesis,” he said.
