Chemicals Remain in Most Treated Water, S...( LISLE Ill. Dec. 5 /- Following a USGS...),Health

LISLE, Ill., Dec. 5 /PRNewswire/ -- Following a USGS study released today showing that man-made chemicals remained in two-thirds of the publicly treated water that was tested, the Water Quality Association is encouraging consumers to educate themselves on possible solutions.

According to a report by the U.S. Geological Survey, low levels of about 130 man-made chemicals were not removed by public treatment processes. The USGS examined water from nine selected rivers used as sources for public water systems. Tests were conducted before and after public treatment processes.

WQA, a not-for-profit alliance of water treatment companies, has become a resource for consumers and public policy makers seeking information about the issue. WQA offers an online fact sheet with answers to the issue of chemicals in water, available at wqa.org.

Filtering systems in the home provide the highest technologies available for treatment of drinking water, according to Joseph Harrison, technical director of WQA. Less than two percent of all water consumed is ingested by humans, making these "point-of-use" systems the most cost-effective and environmentally friendly.

While utilities are required to meet safety standards set by the U.S. EPA, home filtering systems act as a final contaminant barrier and can further purify water for drinking, Harrison said. While specific product performance standards have not yet been developed for every chemical, many point-of-use technologies have proven effective for emerging contaminants.

WQA provides Gold Seal certification for products that remove a variety of contaminants. Consumers can learn about different treatment systems and find locally certified dealers by visiting the WQA Web site's Gold Seal and Find-A-Professional features.
