In short

The Monongahela Tannin is the Three Rivers answer to tannins in well water: a dedicated tannin resin captures the organic material behind yellow/brown tint, musty odor and staining. It is installed for well-water homes across the Greater Pittsburgh area after a water test confirms tannins are the problem.
