is it safe for babies to be exposed to chlorinated water (free chlorine concentration of 1ppm) in swimming pools? eg small splashes of water get on their face, and potentially into their mouths if they lick the water on their gums.

So far it's pretty safe for babies to go into the pool and play with them. And baby lifespan in the pool is not long too, the most 30-60 minutes. So it's kind of pretty harmless to them. There is even baby swimming lesson in swimming pool too. Chlorine is good in a way, it's help to kill bacteria too. http://www.livescience.com/37122-how-chlorine-kills-pool-germs.html http://www.cdc.gov/healthywater/swimming/residential/disinfection-testing.html Something to read about the pretty harmless chlorine.
