Suffolk County issued the following announcement on July 31.
Due to heavy rainfall, the Suffolk County Department of Health Services has issued an advisory against bathing at 61 beaches. The advisory is based on the knowledge that bacteria at levels that exceed New York State standards will affect these beaches.
The beaches covered by the advisory are located in areas that are heavily influenced by stormwater runoff from the surrounding watersheds or adjacent tributaries, and because of their location in an enclosed embayment, experience limited tidal flushing.
The department recommends that bathing and other water contact be suspended in affected areas until the waters have been flushed by two successive tidal cycles (at least a 24-hour period) after the cessation of rainfall. This advisory will be lifted Saturday, August 1, 2020, at 10:00 a.m., unless sampling conducted by the department reveals elevated levels of bacteria persisting beyond the 24-hour period.
Additionally, Bayport Beach and Sayville Marine Park Beach, which closed yesterday due to the finding of bacteria at levels that exceed state standards, remain closed until further testing reveals that the bacteria have subsided to acceptable levels.
