Akmed: I really enjoyed seeing your response. The truth of the matter is that plumbers know remarkably little about water quality, though for the most part are professionals in the highest order to protect the health and safety of the nation.
To that end, I am offering my services in the NY area as an analytical chemist, and I will ONLY work for plumbers, and send my reports to the same. I can tell you what is in the water, and in most cases how much. It is fof YOU, our protector to use that information to recommend the proper course of action.
