Oh my goodness, this is SO helpful! I didn't think it was related to the RO or the softener! Okay, yes, I agree that something is reacting to the copper. Do you know any theories of what that could be? Knowing some ideas would be so helpful. What could be reacting if the pH is normal?
The RO is only one small line that goes from that system to one secondary faucet in the kitchen... We stopped using the RO so we wouldn't stress out that system. That RO water only runs in that one location.
No one analyzed the sludge, despite my efforts to get someone to. They basically said we'd have to test it for something and we can't just do random tests. They said "there's no 'what is this?' test."
Thanks, the town has a team working on it, as well as environmental conservation, the health department, as well as county sanitarians. We called the utility company to ask about electrolysis as an option but the house appears to be grounded properly. Everyone says they've never seen this.
pH...
PLEASE HELP!!
We have blue water in our home that is only visible with a full bathtub amount. It isn't light refraction. It stains laundry, tastes like metal, and when left to sit for 24-48 hours, leaves a blue sharp-like looking sludge. It comes and goes every 6-8 months and no one can figure...
