Filtering systems in the home provide the highest technologies availablefor treatment of drinking water, according to Joseph Harrison, technicaldirector of WQA. Less than two percent of all water consumed is ingested byhumans, making these "point-of-use" systems the most cost-effective andenvironmentally 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 furtherpurify water for drinking, Harrison said. While specific product performancestandards have not yet been developed for every chemical, many point-of-usetechnologies have proven effective for emerging contaminants.
WQA provides Gold Seal certification for products that remove a variety ofcontaminants. Consumers can learn about different treatment systems and findlocally certified dealers by visiting the WQA Web site's Gold Seal andFind-A-Professional features.
