Arsenic (As) is not easily dissolved in water. Therefore, if it is found in a water supply, it usually comes from mining, metallurgical operations or runoff from agricultural areas where materials containing arsenic were used as industrial poisons. Arsenic in water has no taste, odor or color. Arsenic and phosphate easily substitute for one another chemically; therefore commercial grade phosphate can have some arsenic in it. Arsenic is highly toxic and has been classified by the EPA as a carcinogen. These cartridges contain an Arsenic-selective Resin specifically designed to filter Arsenic V and Arsenic III.
