Nineteen Nassau County beaches remain closed Saturday as a precautionary measure, the agency said.
The beaches were closed because of concerns over bacteria, health officials said. During heavy rains, stormwater runoff can sweep bacteria and pathogens into local streams and bays, causing bacterial levels to spike.
The closed beaches include 14 on the North Shore: Centre Island Sound, Creek Club, Lattingtown Beach, Laurel Hollow Beach, Morgan Sound, North Hempstead Beach Park, Piping Rock Beach Club, Pryibil Beach, Ransom Beach, Roosevelt Beach, Sea Cliff Village Beach, Soundside Beach, Stehli Beach and Tappen Beach.
Five closed beaches are on the South Shore: Biltmore Beach Club, Hewlett Point Beach, Island Park Beach, Merrick Estates Civic Association and Philip Healey Beach.
Health department representatives are available weekdays, from 9 a.m. to 4:45 p.m., at 516-227-9717. The Health Department phone number for recorded information on beach closings and openings in Nassau, 516-227-9700, will not be in service until Tuesday, a health official said.
