[Greenbuilding] Acidic Water

[Sally Shivnan]

Acid water has a low pH (the opposite is alkaline, with a high pH) and to 
treat this you use an acid neutralizer (ours uses a mineral bed--a medium of 
some kind, I forget what, that gets backwashed every two days; there's 
another type that injects something into the water to counteract the 
acidity).  Hardness is a measure of mineral content--it's what water 
softeners treat.  We have an acid neutralizer, a softener, a UV light to 
kill any bacteria, and reverse osmosis as a final step for the drinking 
water portion of our water.  (We had TERRIBLE well water and had to do all 
this...)
