Perhaps you've noticed a toddler's sagging swim diaper and wondered if it's really keeping the poop out of your neighborhood pool.

The Centers for Disease Control and Prevention has the answer for you: no.

Last summer, researchers at the federal public health agency collected 161 filter samples from public swimming pools in the Atlanta area. More than half of those samples, 58 percent, were contaminated with E. coli.

That, the CDC reported today, "signifies that swimmers introduced fecal matter into pool water."
