AWWA CEO David LaFrance thanks water professionals nationwide for keeping water safe for drinking
Dec. 16, 2014, marked the 40th anniversary of the Safe Drinking Water Act (SDWA), which today includes regulations for more than 90 contaminants. American Water Works Assn. (AWWA) CEO David LaFrance issued the following statement to mark the occasion.
The MWF refrigerator filter is NSF-certified and removes cysts plus a range of contaminants, including lead and mercury. In addition, it has been tested by a third party to remove more than 94% of five trace pharmaceuticals: ibuprofen, atenolol, fluoxetine, progesterone and trimethoprim. The filter is available for use in GE side-by-side and French door refrigerators.
In 2007, the NSF Intl. Drinking Water Treatment Unit Joint Committee revised the NSF/ANSI Standard 53 protocol for pH 8.5 lead reduction based on a substantial amount of research on particulate and colloidal lead. The research conducted by the NSF task group revealed a great deal of inconsistency in the amount of particulate lead formed from batch to batch and from laboratory to laboratory due to the precipitation of this element from the solution.

Lead has been a hot topic for consumers and the media for many years. We all have heard about the deterioration of U.S. water distribution systems, lead service lines, extremely high levels of lead in Washington, D.C.’s drinking water because of a change from chlorine to chloramine, lead in paint, lead in toys, new lead content laws in California and Vermont (soon to be national)—concerns about lead that will never go away.
Challenges in creating a consistent lead certification protocol
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
Whole house filtration systems are the end of the line in defense against contaminated water. They are becoming more popular as a non-visible way (compared with end of faucet filters) to ensure safety at point of entry in the house.
