Aerating Water to Get Rid of Iron

[chem geek]

Am lead to believe, after reading a while back an American Ground Water Association article, that aerating water by passing bubbles through it releases Iron and other minerals into the air, therby removing Iron from the water. Is this true?

This doesn't sound right to me. The iron that is in water is an iron ion (when dissolved) or typically a solid iron oxide when stained (precipitated) on plaster. To aerate iron or other minerals, they would have to be in some sort of gaseuos form and I just don't see that happening. If you can find the article, post a link and I'll take a look at it.
