POU/POE CASE STUDIES FOR SDWA COMPLIANCE

Picture
State primacy agencies and public water systems were surveyed to better understand how each state utilizes and manages Point-of-Use (POU) and Point-of-Use (POE) technologies for compliance.

 1-Minute Video
​Our Safe Drinking Water Act (SDWA) case studies examine how state primacy agencies and public water systems implement point‑of‑use (POU) and point‑of‑entry (POE) devices to achieve SDWA compliance. A national survey across 38 states finds that 61% of responding states authorize and actively use POU/POE systems, while others cite cost, maintenance, and operational barriers. Detailed case analyses from Arizona, California, New Hampshire, and Oregon highlight policy frameworks, technical requirements, and outreach strategies. This research offers actionable insights into regulatory drivers, water treatment solutions, and consumer protection efforts.
Summaries and educational materials (toolkits, handouts, infographics, etc.) are publicly available resources, and the full scientific reports are free for Water Quality Association (WQA) members.
