LISLE, Ill. — The Water Quality Association (WQA) and the American Society of Plumbing Engineers (ASPE) are preparing to expand the scope of product standard WQA/ASPE/ANSI S-803 (2014): Sustainable Drinking Water Treatment Systems to include ion exchange resin (IER) media and water softeners, according to a press release.

WQA and ASPE are seeking volunteers to help draft the environmental criteria for the additional product types, stated the release.

The WQA/ASPE team has almost completed the process of expanding S-803 product range, which initially only covered activated carbon (AC) filter systems, to include coolers/dispensers and ultraviolet (UV) treatment systems, continued the release.

Regarding the expansion of UV systems and coolers/dispensers, the release reported, “Therefore, the planned expansion into softeners and IER is the next natural step in the evolution of this ground-breaking standard for the water treatment industry."

Individuals interested in joining “WQA’s Standard-Development Working Group” for standard development in sustainable softeners and IER can contact WQA Sustainability Certification Supervisor Stuart Mann at or 630-929-2546, noted the release.
