What New Mexico is doing about PFAS

New Mexico has been active on PFAS enforcement at former military airfields. The New Mexico Environment Department filed suit against the U.S. Air Force over PFAS plumes at Cannon Air Force Base near Clovis and Holloman Air Force Base near Alamogordo, arguing the federal government must fund cleanup and alternate water supplies for affected dairy farms and communities.

State records show New Mexico has not adopted enforceable state drinking water MCLs for PFAS and relies on the federal EPA limits finalized in April 2024. The legislature passed HB 212 in 2022 banning PFAS in firefighting foam used for training exercises.

Public water systems in New Mexico are subject to the federal compliance timeline requiring initial monitoring by 2027 and treatment installation by 2029.

Based on New Mexico Environment Department publications and federal court records.
