Programs and Services

WQA also serves as an educator of water treatment professionals, a certifier of water treatment products, a public information resource and the voice of the water quality improvement industry.

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 its 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.
