EPA Administrator Lee Zeldin visited Onterris' Portland, Maine office to review its PFAS treatment technologies, including the SORBIX RePURE regenerable ion exchange platform, as utilities face new federal water-quality requirements. Onterris has deployed more than 350 treatment systems globally, including PFAS projects at 34 US federal facilities, and says its regeneration process achieves an approximately 80-million-to-one reduction in waste volume. The company is investing in US regeneration capacity and a Regeneration as a Service model, with NSF-certified drinking water resin systems sold in North Carolina and Maine and further deployment planned in Ohio.
