Hard water woes?

[ravenword.livejournal.com]

Hello Davis residents! Recently (well, for several months...) my roommates and I have noticed some mysterious stains appearing on our laundry. They look like either rust stains or bleach stains. My roommate did some Googling and read that chlorine bleach can interact with the iron in hard water to create stains like this, and she was wondering if I could poll the community to see if anyone else has had similar troubles. What say you?
