The number one problem in public pools is not number one as you might expect, but instead, number two.

I think we've all known someone who's peed in the pool right?  Surely it wasn't us, never would we do such a thing.  Turns out, that may be the least of our worries when hanging out in a public pool.

A CDC study found that almost 60% of public swimming pools contained traces of fecal matter. Experts say E. coli bacteria can wind up in the water due to accidents or from traces of fecal matter on swimmers.

The bacteria was found to be worse in public pools than at private clubs.  And while most pool water samples were found not to contain E. coli germs that could cause illness, you may want to think twice about swimming in public pools this summer.
