What Tannins Do in Water
They are created as water passes through peaty soil and decaying vegetation; like trees that were cut down but haven’t been cleared away yet. This causes the water to have a faint yellow to red color, and can cause yellow staining on fabrics, fixtures, and laundry. Tannin may give an unpleasant aftertaste to water. It may also cause water to have a musty or earthy odor.
Are Tannins Safe?
While water affected by tannins does not pose any health or safety risk when consumed or used in the home, it can create some unique problems. Besides the unappealing color, affected water can have a plant-like, musty odor to it and will have an unpleasantly tangy aftertaste when consumed.
This is why it’s important to test your water, so you know what’s in your water, it like Tannins.
