Long story, but I have a friend that is dealing with some serious liver health issues, and one suspect is heavy metals in the water sourced from a well that flows through old galvanized pipes. Anyone here know of a good lab at a reasonable price? Just googling, prices are well over $100, and often triple that. And many (Texas A&M) say not for drinking water. I ordered those cheap strips on Amazon to have a trial against distilled as a control, but not hopeful. Any help is appreciated.
