Officials Recognize POU Industry

After the U.S. Environmental Protection Agency (EPA) finally announced the new maximum contaminant level (MCL) of 10 parts per billion (ppb) for arsenic, an estimated 4,000 community water systems are now left to take measures to lower their arsenic levels, which were previously at 50 ppb.

POU Options for Arsenic

The topic of arsenic has received a lot of press coverage this year, ever since the Bush administration halted the EPA’s newly issued maximum contaminant level (MCL) of 10 parts per billion (ppb). Since then, the MCL was reinstated back to 50 ppb and further discussions and studies have continued. This article will discuss some of these updates.

Self-Cleaning POE System Solves Frequent Filter Clogging Problems

A new self-cleaning system avoids the premature clogging problems associated with conventional carbon filtration systems, while at the same time providing one micron or submicron filtration.As more Americans are aware of the health risks associated with contaminated water supplies, many citizens are turning to filtered water. One couple, Gerry and Candy Rossettie, who bought a 40-year old, 6,000 sq ft home in Sands Point, New York, wanted to be certain they were getting safe water.
