The CDC studied public Atlanta-area pools last summer and found that nearly 60 percent of the filters contained E. Coli, the same bacteria found in human feces.
"It is gross and I don't want my kids to swim," said Earlene Scott.
Officials believe the problem is likely nationwide.
The report says swimmers are often contaminating the water.
"This means that swimmers brought feces in when they had a diarrhea or from stool incident in the water or it could mean that they didn't take a shower before they got into the water and feces rinsed off their bodies," Michele HLavsa with the CDC said.
Here in Tampa the Parks and Rec. director says parents shouldn't worry about dirty-pools. They city's 11 public pools are cleaned multiple times a day.
"It is a continuous filtration system so its on 24 hours a day but then ph and chlorine are monitored every hour and its done by computer," Greg Bayor said.
The CDC recommends taking a pre-swim shower and staying out of the pool if your feeling ill.
As for the little ones make sure they take regular bathroom breaks and check their diapers often.
Swimmers like Nancy Hughes say this "#2 news" won't stop her from taking a dip.
"It looks pretty clean to me and I grew up in the 50s and we didn't think about it back then," Hughes said.
