Officials in Nassau County have temporarily closed close to 20 beaches to swimming over bacteria concerns following heavy rain.
The beaches closed Saturday are mostly on the north shore of Long Island. They include:
Centre Island Sound
Laurel Hollow Beach
North Hempstead Beach Park
Piping Rock Beach Club
Sea Cliff Village Beach
Officials also closed four beaches on the south shore, including Hewlett Point Beach, Island Park Beach, Merrick Estates Vicis Association and Philip Healey Beach.
Storm water runoff after heavy rains can wash things into the water, but health authorities are especially concerned about bacteria from sewage.
