Municipal and community water providers are racing to meet the U.S. Environmental Protection Agency's (EPA) January 23, 2006 deadline for reducing arsenic in drinking water. The new ruling reduces the maximum allowable level of arsenic in drinking water to 10 parts per billion (ppb). Pall Corporation announced today that its membrane filtration technology was granted verification by NSF International Drinking Water Systems Center, a partner of the EPA's Environmental Technology Verification Program, to remove arsenic from drinking water.
