Filtration Avoidance Determination system
E498578
The Filtration Avoidance Determination system is a U.S. regulatory framework that allows certain high-quality surface water supplies, such as New York City’s Catskill-Delaware system, to be delivered without filtration if strict watershed protection and water quality standards are met.
