Chemicals Remain in Most Treated Water, Says Report
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
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
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
More information is available at WQA’s Water Information Library online,
which includes a search feature.
Throughout the year, the Associated Press has reported on pharmaceuticals
being found in water supplies. According to an article in September, almost
one in six Americans may be affected by these drugs in their household water.
