Watts Premier Completes the EPA ETV Program for Removal of Chemical Contaminants in Drinking Water. Watts Premier, a subsidiary of Watts Water Technologies, Inc. announced that it has completed Chemical Contamination testing under the EPA Environmental Technology Verification (ETV) program. Through this ETV testing, the Watts Premier line of reverse osmosis systems demonstrated the removal of minimally 98% of all chemical agents that were introduced in to the WP-4V test unit. Over the life span of the testing, the RO membrane was tested with elevated levels of Cadmium, Cesium, Mercury, Strontium, Aldicarb, Benzene, Carbofuran, Chloroform, Dichlorvos, Dicrotophos, Fenamiphos, Mevinphos, Oxamyl and Strychnine in the test waters. Over the life of the testing, all prefilters were removed from the test unit in order to evaluate the ability of the RO membrane by it self to reduce these contaminants from the drinking water. It was discovered that the Watts WP-4V RO membrane on its own was found to remove 98% or better of all chemicals except benzene, chloroform and mercury.However when tested with the unique VOC chemical reducing post filter (the filter after the RO membrane), the system together removed over 98% of all contaminants including benzene, chloroform and mercury.

Based upon these results, the use of these device would significantly reduce the risk of exposure to these chemical agents in drinking water in the event there is a contamination incident within the municipal or private water distribution system.

" The goal of the EPA ETV program is to further environmental protection by accelerating the acceptance and use of improved and cost-effective technologies. As part of the national Homeland Security effort, NSF through its ETV program has developed a test/QA plan under for evaluating point of use drinking water treatment systems for removal of biological contamination agents. The verifications serve to inform the public of the possible avenues they can pursue in order to provide personal protection against biological contamination agents afforded to them by the use of verified systems. This is accomplished by evaluating the reduction in risk of potential exposure to biological agents in drinking water treated by the tested system in comparison to drinking water directly from the public water supply system.
