This is due to the presence of tannin, also known as fulvic or humic acid, a natural organic material that is created as water passes through peaty soil and decaying vegetation. This can cause water to have a faint yellow to tea-like color, and can cause yellow staining on fabrics, fixtures, china, and laundry. High levels of tannin can give water a tangy or tart aftertaste, as well as a musty or earthy odor. Tannins are more common in surface water supplies and shallow wells than in deep wells. Water in marshy, low-lying, or coastal areas are also more susceptible to tannins.
This mineral stays in solution and cannot be filtered with conventional filters, but our ozone treatment system is more than capable of addressing this challenge. We have processed tannin-stained water directly from a creek source using our system, producing crystal clear, uncontaminated water.
