Rule Background

In December of 2021, EPA published UCMR 5 to establish nationwide monitoring for 29 per- and polyfluoroalkyl substances (PFAS) and lithium ink drinking water served by PWSs. The rule requires participating PWSs to sample from 2023-2025 and report final results through 2026. America’s Water Infrastructure Act of 2018 requires all small PWSs serving between 3,300 and 10,000 people to participate in UCMR (subject to availability of appropriations and lab capacity) and specifies that a representative sample of small PWSs serving fewer than 3,300 people participate.
