The Nassau County Department of Health is issuing an advisory against bathing at 14 beaches, effective today.

This advisory is issued as a precautionary measure for beaches known to be impacted by stormwater runoff caused by heavy rainfall.  

Stormwater runoff can impact bathing water quality by elevating bacteria levels, which may cause exceedances of the New York state standard for bathing water quality.

This advisory will be lifted at 7 a.m. Wednesday,  unless there is additional heavy rainfall or water samples reveal elevated bacterial levels.
