Tannins in Water

Tannins come from decomposed natural organic material. When water passes through peaty soil and decaying vegetation it picks up natural tannins, also known as fulvic and humic acids.  Tannins can cause well water to have a light yellow to tea-like color. Tannins may cause yellow staining in laundry. Tannins can cause a tart aftertaste and earthy odor to water.


Health Effects of Tannins: Tannins are not associated with health risks at the levels found in drinking water. Tannins creates aesthetic problems with taste, odors and in the laundry.


How to Remove Tannins:  A WECO Point Of Entry (POE) activated carbon backwashing filter will remove tannins and correct taste and odor problems.
