Reliability of state "healthy beaches" Web site questioned
Visitors crowd Shell Point Beach in Wakulla County on April 25 despite an advisory against swimming that was correctly posted on a state website: www.floridashealth.com/beachwater.
Heading to the beach this summer? A good idea might be to check the Florida Department of Health Web site to see if there are advisories against swimming because of bacteria.
But a recent review by FloridaEnvironments.com of DOH's database of swimming advisories found numerous reporting errors. Bacteria tests are an indicator of fecal pollution from stormwater runoff, pets, wildlife and human sewage, according to the department.
Much of the state, including the Atlantic Coast beaches, have not been under advisories this spring. But there have been advisories at some beaches in the Florida Panhandle and Big Bend, where most of the reporting problems also were found.
Some advisories weren't posted when they should have been, or they were lifted when there were no test results to suggest it was safe to swim. Testing wasn't done at Taylor County beaches for several weeks and some test results weren't reported in Gulf County -- therefore no advisories were issued.
David Polk, state healthy beaches coordinator at the Florida Department of Health, attributed the Web site inaccuracies to a variety of administrative, computer and clerical problems. He began correcting some of the inaccuracies last week after FloridaEnvironments.com raised questions.
"I'm going to go back and review our policies to see if we need to make further improvements," he said.
At Dixie County's Shired Island, advisories were inadvertently lifted for 12 weeks when they should have been maintained, Polk said. He corrected the Web site last week.
At Taylor County's four beaches where water is tested, the state web site indicated that advisories were lifted when there were no test results to confirm swimming safety.
Polk said, "That was an administrative snafu by me."
He explained that advisories are automatically lifted by the computer software if there are no test results -- unless he takes action to maintain the advisory, which he failed to do. Department policy, he said, requires the advisory to be maintained until there are test results to show bacteria levels have dropped.
The Taylor County Health Department also failed to conduct testing between March 10 and May 5 that it was supposed to do, Polk said.
The Florida Department of Health allowed Taylor County to quit testing during the winter months when there are few swimmers and when low tides create mud flats that are difficult to cross to obtain water samples, Polk said.
Taylor County began retesting on March 3, and new advisories were issued on the state Web site for Dekle Beach, Cedar Beach and Hagens Cove. Then the advisories were lifted, according to the web site, after Taylor County Health Department quit testing from March 16 to May 5.
After testing resumed on May 5, new advisories were issued for Dekle Beach and Hagens Cove.
Taylor County Environmental Health Director James Rachal said in an e-mail to FloridaEnvironments.com that beaches were not tested because of local flooding and other health priorities, but he couldn't be reached on the telephone to elaborate. He also said the advisories against swimming remained even while the Web site erroneously indicated they had been lifted.
Polk said he plans to meet with Taylor County officials to discuss the testing.
"We may have to re-evaluate how they continue the program," Polk said. But he ruled out the possibility that beach testing would stop in Taylor County.
In Franklin, Levy and Wakulla counties, there were single instances of advisories being lifted on the Web site when there were no test results to show that it was safe to swim.
And at Dixie Belle Beach in Gulf County, there was no health advisory issued on April 13 despite high levels of enterococcus bacteria. Polk said he would need to find out why there was no advisory issued. Test results also were not reported for at least three weeks this spring because sampling results were not provided by a laboratory, Polk said.
Polk said the DOH beach testing Web site still is a useful tool because residents and visitors can view water quality results at their favorite beaches even if an advisory isn't correctly posted.
"We still think the Web site is a credible means to determine whether you should or should not swim that day," he said.
