Beach water can change within a day of heavy rain. A result here is only as current as the date shown next to it, and outside Memorial Day to Labor Day most beaches are not tested at all. No result listed does not mean the water is safe. Look for posted signs at the beach, and check the agency’s own page before you swim.
