Two more Nassau County beaches, Sea Cliff Beach and Island Park Beach, were closed to swimming after high levels of bacteria were found, the county health department said.
Three additional beaches — Philip Healey Beach and Biltmore Beach Club in Massapequa and Morgan Sound in Glen Cove — also remain shut for the same reason, a statement from health officials said.
The closures will continue until testing reveals "acceptable limits" of bacteria, the health department said.
Higher bacteria levels arise from stormwater runoff, which occurs when the ground cannot absorb all the rain that falls and can contaminate bodies of water with effluents from leaking cesspools and septic systems, pesticides, fertilizers, oil and various kinds of debris.
