Discolored water in ground water systems is usually the result of the oxidation of soluble iron and/or manganese that occur naturally in water. The discolored water is not harmful, but is unsightly and causes staining of clothes, porcelain sinks and tubs, and exterior concrete or brick. The discoloration can often impart an undesirable taste and odor making it less than pleasant to drink.

Two frequently used methods to alleviate the problem of discoloration are to flush the lines frequently or use polyphosphates. The flushing of lines wastes water and is surprisingly expensive. Since water is a precious natural resource that is becoming less plentiful all the time, it should not be wasted by excessive and unnecessary flushing. The economical alternative is the use of polyphosphates. Treatment for discolored water with Water Solutions Unlimited inhibitors is very cost effective. Minimal chemical feeding equipment is required. WSU inhibitors control the iron and/or manganese immediately after the water is pumped from the well but before the addition of the chlorine. The chemical additive keeps the iron and/or manganese in the soluble form and prevents the oxidation process from completion. Without the WSU inhibitor the metal ions will oxidize and discolored water will result. This discoloration must be removed either by flushing or some costly mechanical process. Controlling iron and/or manganese with WSU products does not cause any problems with taste, odor, or water clarity. Polyphosphates such as Water Solutions Unlimited's have been used in potable water systems for years.
