Health officials are advising against swimming at 47 Suffolk County beaches after heavy rainfall Tuesday.
In a Wednesday news release, the Suffolk Department of Health Services said the advisory is based on "the potential that bacterial numbers in excess of New York State standards, resulting from the heavy rain, will impact these areas."
The beaches are located within and adjacent to several North Shore embayments -- Cold Spring Harbor, Huntington Harbor and Bay, Centerport Harbor, Northport Harbor and Northport Bay, Port Jefferson Harbor, and Stony Brook Harbor -- and are "directly impacted by nearby stormwater discharges and are heavily influenced by stormwater runoff from the surrounding watersheds and/or adjacent tributaries," according to the release.
The bathing advisory is expected to be lifted by 9 a.m. Thursday, unless sampling indicates elevated bacterial numbers persisting beyond the 24-hour period.
Copiague Harbor Beach in Copiague remains closed after bacterial levels were found in excess of acceptable criteria.
The New York State Office of Parks, Recreation and Historic Preservation also said Wednesday that swimming is prohibited at Field No. 6 at West Beach located within Heckscher State Park in East Islip.
The closing is because of unacceptable water quality samples, the agency said, and is a precautionary step to assure protection of the health and safety of our swimmers.
Field No. 8, which usually is closed on weekdays, is open Wednesday to give swimmers another option during the hot weather.
