We have well water. We don't drink it. We buy bottled water or put one of those purifiers on the faucet. They (health officials) tell everyone to pour about a cup of clorox in the well once a year or so.

As for the stains in the bathtub/showers, I keep the automatic daily shower cleaner in our showers. Last one to shower in the morning pushes the button.

We've switched our little dog over to bottled water too. We always noticed our other dog that died after 17 years, he always had horrible breath. When we got our new little dog, he didn't have bad breath when he got here. Once he was at our house for a while and was drinking well water, his breath started smelling. Now we've switched him to bottled water and his breath is fine now.

The well has been tested and it's fine. It's just the minerals, etc. in it. But it does makes you wonder, you know?? That's why we switched to bottled water.
