ATLANTA (AP) -- Health officials say many public swimming pools aren't as clean as they should be.

According to a new report, one in eight public swimming pools were shut down after inspections. Some were too dirty and some had other problems, like missing safety equipment.

Kiddie pools had the most disinfection problems, and were commonly contaminated by bits of fecal matter. One healthy official called the finding "concerning."

The Centers for Disease Control and Prevention released the report Thursday. It's based on more than 120,000 routine inspections of public swimming pools, including those in public parks and at hotels and motels. The checks were done in 2008 in 13 states.
