Arsenic, a knowncarcinogen and major health hazard, is found in the drinking water of 34million Americans. Using the patented Stevens' Direct CoprecipitationFiltration process, the U.S. EPA hopes to reduce the current standardfor arsenic levels from 50 parts per billion down to possibly as low as10, 5, or even 3ppb. The filtration process has been successful in theremoval of arsenic in groundwater systems throughout the U.S. The changeis estimated to cost over $14 billion, but officials see the newfiltration system as the most safe and economical way to remove arsenicand other dangerous heavy metals from drinking water.
