 Well, I think I would get the well people out there again and find out what's going on. Off the top of my head, I can't tell you. I do know if it's green. You could have a high copper or iron content, and you may need a specific filter for that. I don't know what your test numbers were. Obviously, chlorination is step one. I don't know if there's anything else that's needed. It sounds like there is.
