Find Certified Water Treatment Professionals

Certified water treatment professionals are individuals who have completed a voluntary credentialing process through WQA's Professional Certification Program. To become a WQA certified professional, the candidate must pass a comprehensive examination and accept WQA's Code of Ethics for the Water Quality Improvement Industry. WQA's program tests and certifies only individuals, not dealerships or companies. Certified professionals are typically employed by WQA member companies, but WQA membership is not required for certification.
