SANTA ROSA BEACH — The water at a South Walton County beach is a potential health risk, according to the Florida Department of Health in Walton County.

A health advisory was issued Thursday for Dune Allen Beach based on the enterococci standard recommended by the Environmental Protection Agency, a DOH news release said.

The previous health advisory for Grayton Beach has been lifted.

The water samples are analyzed for enteric bacteria that normally inhabit the intestinal tract of humans and animals. The fecal pollution can come from stormwater runoff, pets, wildlife and human sewage, according to the release.

The bacteria may cause disease, infections or rashes to people in the water, the release said.

The results of all seven sites are as follows:
