Something else. Is this well new construction or did you purchase this home and this is your only source of water? If the latter was the arsenic level part of the prepurchase acknowledgement by the seller? If you purchased the house and this is the sole source of water than I think you may want to speak to a lawyer and if purchased on a VA loan, the VA.
There could be a lot of people crosswise from the realtor to the prior owner. The prospective owner has a legal right to know of certain deficiencies prior to purchase. I can not believe that water contaminated with heavy metals isn't one of them.
We've got 2 wells. The one that goes to the house is the one with arsenic. The other one is an older ag well, which is quite a ways downhill from the garden and chicken area.
This is an older home, existing wells. We have a conventional loan, and believe me we nearly backed out because of this issue but we did a whole lot of research and decided to manage by doing RO water for drinking.
So, thing is, they didn't even require this test to purchase the home. The coliform testing was required, and we purchased lead and arsenic on our own. Even the water lab didn't recommend arsenic testing. But we insisted, and lo and behold, here we are today. My realtor said we did the more testing than any of her clients, and she's been a realtor for like 30 years. People just don't care (?). It sounds scary but plenty of people have arsenic in their water. It's very common in Arizona, people just RO their water. Can even be in city water. The guidelines a few years ago was 50ppm and under, they only recently changed it to 10ppm, so our water at 20ppm is not crazy high. I can talk your ear off about water, so to speak. I was just hoping maybe someone else would have some experience and can give me some insight.
Believe me, if you saw my place, you wouldn't be recommending distilling my water haha. How do you even do that? Boil it on the stove? Maybe this is the wrong forum for me
