The Niagara County Department of Health has issued a beach advisory at Olcott Beach, located in Olcott, and is expected to remain in effect until further notice.
The Health Department says recent surveillance sampling conducted on Wednesday has determined the water is not suitable for swimming because of "unsatisfactory bacteriological water quality." Health officials are continuing to monitor the situation closely and say they will reopen the beach for swimming when conditions return to a safe level.
Additional information is posted on the Niagara County Department of Health website.
