The Florida Department of Health in Walton County (DOH-Walton) conducts regularly scheduled saltwater beach water quality monitoring at seven sites through the Healthy Beaches Monitoring Program. Samples are collected from March through the end of October. The water samples are analyzed for enteric bacteria (enterococci) that normally inhabit the intestinal tract of humans and animals, which may cause human disease, infections, or rashes. The presence of enteric bacteria is an indication of fecal pollution, which may come from storm water runoff, pets and wildlife, and human sewage. The purpose of the Healthy Beaches Monitoring Program is to determine whether Florida has significant coastal beach water quality problems and whether future beach monitoring efforts are necessary.
| Site | Name | Enterococci | Water Quality |
| SP-1 | Miramar Beach | 8 | Good |
| SP-3 | Dune Allen Beach | 8 | Good |
| SP-4 | Blue Mountain Beach | 60 | Moderate |
| SP-5 | Grayton Beach | 44 | Moderate |
| SP-7 | Holly Street Beach | 72 | Poor |
| SP-8 | Eastern Lake Beach | 276 | Poor |
| SP-9 | Inlet Beach Access | 52 | Moderate |
Water quality classifications are based upon United States Environmental Protection Agency’s (EPA’s) recommended criteria and Florida Healthy Beaches Program Categories:
Good = 0 – 35 Enterococci CFU per 100 ml of marine
Moderate = 36 – 70 Enterococci CFU per 100 ml of marine water
Poor = 71 or greater Enterococci CFU per 100 ml of marine water
Health Advisories has been issued for the Eastern Lake Beach access and the Holly Street Beach access based on the enterococci standard recommended by the EPA. This should be considered a potential health risk to the bathing public.
