The swimming advisory posted on October 4, 2017 has been lifted for the following areas: Crandon North, Crandon South and Key Biscayne Beach Club.
Analyses of water samples from these beaches collected on October 9, 2017 met the Florida Department of Health's recreational water quality standard.
The Florida Department of Health in Miami-Dade County has been conducting marine beach water quality monitoring at 17 sites, including the beach sites at Crandon North, Crandon South, and Key Biscayne Beach Club, weekly since August 2002, through the Florida Healthy Beaches Program. The sampling sites are selected based on the frequency and intensity of recreational water use and the proximity to pollution sources. The water samples are being analyzed for enteric bacteria enterococci that normally inhabit the intestinal track of humans and animals, and which may cause human disease, infections, or illness. The prevalence of enteric bacteria is an indicator of fecal pollution, which may come from storm water run-off, wildlife, pets and human sewage. The purpose of the Florida Healthy Beaches program is to determine whether Florida has significant beach water quality concerns.
