- You may be confusing this with the question of soft vs. hard water.
- Soft water is more likely to dissolve certain metals in the pipes
- (I have a vague recollection that it's more acidic than hard water,
- but I wouldn't bet on this), so if your pipes are old and have lead
- solder, soft water is more likely to contain dissolved lead. But
- I've never heard anyone claim that the mineral content of hard water
- is enough to do you any good or harm. (Yes, there are a few odd
- exceptions here and there: for instance, moderate levels of naturally
- occuring fluorides will help prevent tooth decay in kids who drink
- the water, and really high levels can cause tooth mottling, but
- these aren't all that common.)
