SOUTHAMPTON - Researchers from Stony Brook University testing the water around Long Island say the water surrounding parts of New York City is actually cleaner than water in some parts of the East End.

The crews tested the water for oxygen, salt content, pH, phytoplankton and algae.

Dr. Christopher Gobler, from the university's Marine Science Center, says he was surprised to find water with more algae blooms on the South Shore than in Jamaica Bay or the western Long Island Sound.

Doctoral candidate Ryan Wallace says the algae blooms because of excess nitrogen, due to the overuse of lawn and farm fertilizer.

The testing will continue through the summer and into the fall.

Stony Brook University is sharing its water quality data with the state Department of Environmental Conservation, as well as the Nassau and Suffolk health departments.
