Florida 2012 Beachwater Quality Summary
Reported Sources of Beachwater Contamination
(number of closing/advisory days)
- 1,813 (78%) stormwater runoff
- 1,627 (70%) wildlife
- 1,206 (52%) sewage spills/leaks
- 1,124 (48%) other contamination sources
- 432 (19%) unknown contamination sources
(Totals exceed total days and 100% because more than one contamination source was reported for most events.)
With its year-round swim season and more than 1,000 miles of coastline, Florida has the most coastal swimmers in the nation. The state has more than 600 public coastal beaches stretching along its Atlantic and Gulf of Mexico shores. A national survey on recreation and the environment in 2000 estimated that about 14 million people visit Florida’s beaches annually.
What are the Water Quality Challenges and Improvements in Florida?
Hurricane Sandy was one of the largest storms ever to hit the northeastern United States. Killing 159 people and causing an estimated $70 billion in damage in eight states, Sandy was the most destructive hurricane of the 2012 Atlantic hurricane season and the second-costliest hurricane in U.S. history. Sandy hit southern Florida on October 25, 2012, bringing tropical-force winds and heavy rains for several days. Tropical storms prior to Sandy also left Florida with more than 2 feet of rain. Stormwater runoff from this heavy rainfall caused an increase of fecal indicator bacteria and affected beachwater quality.
Improved Public Information
In February 2013, the Florida Department of Health (DOH) updated its Healthy Beaches web page to make it more accessible to the public and informative. In the 2013 monitoring season, DOH plans to add the monitoring results for more than 100 freshwater (inland) bathing beaches to its marine Healthy Beaches web page.
What Does Beachwater Monitoring Show?
In 2012, Florida reported 636 coastal beaches, of which 76 (12%) were monitored once a week and 184 (29%) every other week; 376 (59%) were not monitored. In 2012, 6% of all reported beach monitoring samples exceeded the state’s daily maximum enterococcus standard of 104 colonies/100 ml and/or a fecal coliform standard of 400 colonies/100 ml, or both. The beaches with the highest percent exceedance rates of the state standards in 2012 were Garniers in Okaloosa County (83%); Monument Beach in Gulf County (72%); Rocky Bayou (Fred Gannon State Park) (61%) and Liza Jackson Park (50%) in Okaloosa County; Bayview Park in Escambia County (45%); Lincoln Park (45%) and Poquito Park (38%) in Okaloosa County; and St. Joe Beach in Gulf County (32%). Okaloosa County had the highest exceedance rate of the daily maximum standard in 2012 (35%), followed by Gulf (29%), Walton (21%), Escambia (16%), Bay (12%), Hillsborough (9%), Sarasota (5%), Santa Rosa (5%), Monroe (5%), Broward (5%), Martin (5%), Pasco (4%), Pinellas (4%), Miami-Dade (2%), St Lucie (2%), Manatee (2%), Charlotte (1%), Franklin (1%), Brevard (1%), Lee (1%), and Palm Beach (1%). No samples taken in Volusia, Hernando, Wakulla, Flagler, Indian River, St. Johns, Collier, Duval, and Nassau Counties exceeded the daily maximum standard. NRDC considers all reported samples individually (without averaging) when calculating the percent exceedance rates in this analysis. This includes duplicate samples and samples taken outside the official beach season, if any.

What Are Florida's Sampling Practices?
Monitoring occurs year-round, but the peak season is from April to mid-September. In 2011, Florida eliminated state funding for beachwater quality monitoring, and the program is now funded only by the federal BEACH Act grant. However, in 2012, several county health departments used their own funds to conduct increased sampling beyond the program baseline.
The beachwater quality monitoring program is administered by the Florida DOH, which determines sampling practices, locations, standards, and notification protocols and practices throughout the state. Samples are collected 18 inches below the surface in water that is approximately 36 inches deep, usually in the morning. Beaches are prioritized for monitoring on a county-by-county basis. Priority for monitoring is given to beaches that are more heavily used, that have potential pollution sources nearby, and that are affected by stormwater runoff. While this ensures that the most critical beaches in each county are monitored, there are a wide variety of beach characteristics in Florida, and beaches chosen for monitoring in one county may not be as important as those left unmonitored in another county.
Sampling frequency does not increase after an advisory is issued.
How Many Beach Closings and Advisories Were Issued in 2012?
Total advisory days for 232 events lasting six consecutive weeks or less increased 22% to 2,328 days in 2012 from 1,915 days in 2011. In previous years there were 3,052 days in 2010, 2,201 days in 2009, 2,067 days in 2008, 3,139 days in 2007, 2,686 days in 2006, and 2,991 days in 2005. In addition, in 2012 there were 6 extended events (378 days total) and 1 permanent event (113 days total). Extended events are those in effect more than six weeks but not more than 13 consecutive weeks; permanent events are in effect for more than 13 consecutive weeks. For the 232 events lasting six consecutive weeks or less, 100% (2,328) of advisory days were due to monitoring that revealed elevated bacteria levels.
How Does Florida Determine When to Warn Visitors About Swimming?
The DOH does not have authority to close Florida beaches; advisories are issued instead. Near-real-time data are posted on the Healthy Beaches web page; in addition, when there is an advisory, signs are posted at the beach and the media is alerted.
Florida applies the U.S. EPA’s marine designated beach area criterion for enterococcus: a single-sample maximum of 104 cfu/100 ml; for beaches that are sampled at least weekly, a 5-week geometric mean of 35 cfu/100 ml may also be used. In the past, Florida also applied a fecal coliform single-sample maximum standard of 400 cfu/100 ml. However, the state stopped using the fecal coliform standard when state funding was eliminated in July 2011. Some counties are subsidizing their beach monitoring and are continuing to monitor for fecal coliform and to apply the 400 cfu/100 ml standard.
In most coastal counties, officials issue an advisory if a standard is exceeded. However, if the county can conduct follow-up sampling within the same week, the beach may be resampled before an advisory is issued. If the resample confirms an exceedance, an advisory is issued.
Pinellas County has a preemptive rainfall standard for two of its marine beaches: Maximo and North Shore. Maximo Beach’s standard is 0.8 inch within a 24-hour period, and North Shore Beach’s standard is 1 inch within a 24-hour period. Martin County has a preemptive standard based on turbidity. Most counties will warn against swimming after a sewage spill until sampling results are satisfactory. After a hurricane or tropical storm makes landfall, precautionary advisories are issued.
Additionally, Florida tracks the presence of harmful algal blooms in marine water and freshwater and reports findings on line.
