The interest in reducing environmental lead exposure is evident with the recent revision by the U.S. Environmental Protection Agency (EPA) for the nation’s Air Quality Standards, which were lowered from 1.5 to 0.15 ug of lead per cubic meter of air. “With these stronger standards, a new generation of Americans is protected from harmful lead emissions, especially children,” said EPA Administrator Stephen L. Johnson. The same goal was desired for the drinking water lead standard, which the EPA lowered in 1998 from 50 to 15 µg of lead per liter of water.
Elevated levels of lead in drinking water occur despite government action
A recent third-party study by Minnesota-based Water Science & Marketing (WSM), LLC, identified commercially available point-of-use (POU) treatment devices as effective for removing perfluorochemicals (PFCs) from drinking water supplies. Stephanie Harris, managing editor of Water Quality Products, recently spoke Phil Olsen, partner and project manager for WSM, about the findings of this study.
