NSF International has released four final verification reports on arsenic treatment technologies. The reports were issued by the EPA/NSF Environmental Technology Verification (ETV) Drinking Water Systems Center.
"These reports are an important step in protecting the public from arsenic exposure," said Bruce Bartley, NSF's technical manager in the ETV DWS Center. "By providing consumers with proven results of product evaluations, the evaluation reports accelerate the implementation of new drinking water technologies into the marketplace."
The ETV DWS Center reports demonstrate a significant reduction of arsenic in drinking water. These tests were performed in small communities in three states in conjunction with Delta Industrial Services and the University of Alaska at Anchorage; Watts Premier and MWH in Thermal, CA; Kinetico, Inc. and Alcan Chemicals with Gannett Fleming in Carroll Township, PA; and ADI International with Gannett Fleming in Sellersville, PA.
In 2001, the U.S. Environmental Protection Agency issued a new arsenic maximum contaminant level (MCL) of 10 micrograms per liter ((µg/L). As of January 23, 2006, all public water systems will be required to comply with the 10 µg/L MCL.
With assistance through an EPA grant, NSF International entered into an agreement on October 1, 2000, with the EPA to form the ETV DWS Center. The center is dedicated to providing independent performance evaluations of drinking water technologies and helping small communities comply with the 10 µg/L MCL.
