How Safe Is Your Local Beach?
Report card rates cleanest and most contaminated beaches across U.S.

WEDNESDAY, June 26 (HealthDay News) -- If you're not careful, you may bring something other than sand and wet swimsuits home from a day at the beach this summer.
Released Wednesday, the report card on more than 3,000 of the nation's beaches shows that the water can put swimmers at risk for catching a range of bacterial and viral illnesses.
"There's a silent and invisible danger," said Steve Fleischli, director of the water program at the Natural Resources Defense Council (NRDC), which produces the yearly report.
Although the number of beach closings and advisories about polluted water at coastal U.S. beaches last year was down 14 percent from 2011, there were more than 20,000 beach closing and advisory days throughout the nation. Fifty-nine beach closing and advisory events lasted longer than six weeks, and 38 such events lasted 13 weeks in a row.
The decline was attributed to a substantially drier beach season in large parts of the continental United States and Hawaii. Rainier seasons tend to be associated with higher numbers of advisories because raw sewage can overflow from treatment plants after periods of intense rain.
The high number of closings and advisories shows that beaches have a serious water pollution problem, Fleischli said. "Too many beaches are sick," he added.
Bacteria levels that exceed quality standards established for beach water were the top reason beaches were closed or advisories were issued. High levels of bacteria suggest the presence of human or animal waste, according to the NRDC.
Overall, 7 percent of beach water samples violated public-health standards, said Jon Devine, senior water attorney for the NRDC. The Great Lakes had the highest contamination rate, at 10 percent of samples, while Delaware had the lowest, with 3 percent of beach water samples showing bacteria.
The U.S. Environmental Protection Agency (EPA) estimates that up to 3.5 million people become ill from contact with raw sewage in beach water every year, according to the report.
The NRDC experts estimated that the number could be even larger, as many of those who develop gastrointestinal or other illnesses after a day at the beach don't associate their illness with the ocean, or fail to report it.
