New Mexico context
Radon, wildfire, water-supply scarcity
New Mexico has Zone 1 radon coverage statewide. Wildfire risk in northern + central forests; the 2022 Hermits Peak/Calf Canyon Fire was the largest in NM history. Water-supply scarcity drives compliance pressure on small rural EPA SDWIS systems.
