The industries devoted to treating and delivering water are complex and varied. WQA primarily represents the sector of the water treatment industry devoted to treating water on the homeowner's or business-owner's property. We often refer to this aspect of treatment as the Final Barrier that prevents waterborne contaminants from entering a home or business. Whether your water arrives from a community treatment plant, municipal well or other source, WQA's member companies are committed to making that water safe and aesthetically pleasing for those who consume or use it.

WQA is a resource and information source, a voice for the industry, an educator of professionals, and laboratory for product testing.

Through the industry’s research arm, the Water Quality Research Foundation (WQRF), significant resources are being dedicated to independently conduct studies that show the benefits of treated water. 

Through our Gold Seal Product Certification Program, WQA offers a certification program to help manufacturers assure their devices conform to national consensus safety and performance standards. We provide manufacturers with independent testing and certification to such standards for a variety of drinking water treatment products, which include rigorous laboratory tests, literature review and materials assessment.

We also provide education to professionals. Dedicated to upholding high standards of performance that make sure consumers have confidence in the people providing and servicing the treatment solutions, WQA’s Professional Certification Program is one of a kind.  As a result, thousands of certified professionals work every day in homes and businesses throughout the nation.

In everything we do, we are proudly dedicated to helping business people serve the public with integrity, quality, and professionalism.

The Water Quality Association was created in 1974 from the merger of two trade associations, Water Conditioning Association International (representing water treatment equipment dealers) and the Water Conditioning Foundation (representing water treatment equipment manufacturers and suppliers).
