My parents recently bought a home in an area that has a "neighborhood water supply", whatever that means. Suddenly, their hot water has started having a green tinge; the neighbors say they've all had this problem off and on, and it's due to excess acidity in the water. The fellow who nominally runs the water supply says things like "I don't know anything about water" and is generally not interested in the problem. That's perhaps not surprising: the neighbors say this goes back over two decades! Anyway, the conventional wisdom is that the problem is due to the acidity leaching copper from the pipes, and that the solution (!) is not to drink the water.
We'd like to understand this better. I was thinking that since it's just the hot water, could it be aggravated by a depleted hot-water tank anode?
My parents have tried contacting folks like the local EPA office, and haven't gotten very far. Any suggestions for how to approach analyzing the problem and solving it would be appreciated! I'm remote, so I can't do much for them other than make suggestions, alas.
Thanks, ...phsiii
