> According to Brian Spear, whose company handled the chemical filtration of the pools used for U.S. Olympic Swim Trials, the potent smell associated with swimming pools is the byproduct of odorless chlorine reacting with organic compounds in the water, like hair or dead skin. Or urine.

Interesting...so if a pool "smells like chlorine," that means it's very dirty?
