Water Filtration - Arsenic Removal

When arsenic (As) is present in drinking water, it can exist in two forms: As(III) and/or As(V). Both forms of arsenic are potentially harmful to human health.If chlorine is present in your water, As (III) will be converted into As(V). GE Reverse Osmosis Systems can remove As(V). In order to be assured that all of the arsenic in the drinking water can be removed by GE Reverse Osmosis systems, the water must have been treated with chlorine.The Reverse Osmosis system MUST NOT be used to remove arsenic from water that has not been treated with chlorine.Chloramines (also known as Combined Chlorine) is often used in place of chlorine, but may not be sufficient to convert all of the As(III) to As(V).Prior to using a Reverse Osmosis system to remove arsenic from drinking water, you should contact your local water utility to verify that the water has been treated with chlorine. In addition, the consumer should have the treated water tested for total arsenic content, to verify that arsenic reduction is being achieved and the Reverse Osmosis system is functioning properly.Additional information regarding arsenic in drinking water can be found on the U.S. Environmental Protection Agency (EPA) website at http://water.epa.gov/lawsregs/rulesregs/sdwa/arsenic/index.cfm .
