Giving water to babies / water for bottles ?'s

[Erinne]

Hijack, sorry!
Hi Beaverton mama, maybe you can help me. I live in Portland but I work in Beaverton, so I could bring a jug to take some tap water from Beaverton and have a choice between the waters, but I'm not sure if one is better than the other. Do you know if either city adds floride to their water? I just moved to Oregon, and so far I have been serving Portland water that has been through the Brita filter, but I don't know if I should just bring some Beaverton water home. I'm paranoid, I know! And if you don't know, that's cool too! Thanks!
