Nassau County is advising residents not to swim at 18 area beaches.
The advisory was issued Thursday as “a precautionary measure for beaches known to be impacted by stormwater runoff caused by heavy rainfall,” the county Health Department said in a news release. “Stormwater runoff can impact bathing water quality by elevating bacteria levels,” which may exceed state water quality standards.
Health officials said the advisory will be lifted at 9 a.m. Friday “unless there is additional heavy rainfall or water samples reveal elevated bacterial levels.”
Separate from the advisory, Biltmore Beach in Massapequa remains closed until further notice, officials said.
The advisory is in effect for:
Centre Island Sound, Bayville
Creek Club, Lattingtown
Lattingtown Beach, Lattingtown
