WQA supports Chicago’s use of filters for some homes after elevated lead levels found in drinking water
Association offers resources to educate consumer on lead issues

LISLE, Ill. – The Water Quality Association supports the decision to offer free water filtration systems to about 30,000 metered homes in Chicago after tests showed elevated lead levels in about 17 percent of homes tested. The city reportedly plans to continue testing of up to 165,000 metered homes over the next two years.

“We believe certified Point of Use devices such as pitchers and filters are a highly effective means of treating water with lead contamination,” said WQA Executive Director Pauli Undesser. “We’re glad to see the City of Chicago taking action and continuing to test more homes.”

 Drinking water that meets federal guidelines for safety when it leaves the treatment facility travels through miles of pipes and fixtures on its way to homes, and lead can leach from lead service connections, from lead solder used in copper piping, and from brass fixtures.

Home water treatment products are considered the preferred method for lead removal. However, devices and systems currently on the market may differ widely in their effectiveness in treating specific contaminants, and performance may vary from application to application. Selection of a particular device or system for health contaminant reduction should be made only after careful investigation of its performance capabilities based on results from competent equipment validation testing for the specific contaminant to be reduced.

 On WQA’s website, consumers can access Frequently Asked Questions about lead or download a fact sheet. School administrators can download information to help them keep lead out of school drinking water. Consumers can search for products found effective at reducing lead in the drinking water supply.

 WQA offers training and certification for professionals who can conduct testing and recommend appropriate remedies for specific contamination issues. WQA tests products for effectiveness, offering Gold Seal certification to those who meet independently established standards.
