Recommended for targeted testing of tannins in drinking water. Tannins are a naturally formed, organic material and are commonly described as "fulvic" or "humic acids". They form when vegetation is degraded and fermented, and then enters the water supply. This package is ideal for clients on well water–particularly those noticing yellow coloration, staining of fabrics, fixtures, and china. Tannins also often impart a musty/earthy odor in water and can lead to unpleasant taste.

This Tap Score water test package provides all required materials to properly collect and submit a sample for certified laboratory testing. Reported results will include detailed, quantified analysis of tannins.

What our scientists say:

“ Tannins are a natural organic material that often results from contact with decaying vegetation. While they are not known to cause health problems, tannins can cause water to appear yellow, taste tangy, smell musty, and leave stains. "


This is the right test if you:

    • Are served by a private or shared well.
    • Water tastes tangy or tart.
    • Water smells musty.
    • Water appears discolored, ranging from light yellow to dark tea.
