Tannin Water Test


Tannins are fermented organic materials that can be present in well water or city water supplies. While they don’t harm health, they discolor water and give it a tangy aftertaste and a musty odor.

Is Tannin in My Water Harmful?
Tannins enter water as it passes through decaying vegetation. They dye water brown and can cause yellow or brown stains on dishes and fabrics. They do not pose a health threat. Differentiating staining from tannins or minerals like iron or manganese may require a scientific test.

How Much Does a Tannin Water Test Cost?
This test costs $30 and will enable you to design the correct water treatment system to remove these organic materials from your water.
