Wildfire Aftermath Reveals Toxic Groundwater Contamination in Mora County

In November 2025, a concerning discovery has emerged in Mora County, New Mexico, three years after the devastating Hermits Peak/Calf Canyon Fire. Groundwater testing has revealed the presence of elevated levels of heavy metals, including antimony, arsenic, and uranium, in private wells across the region.

The state Department of Health is now advising Mora County residents to have their wells tested for heavy metals and to rely on bottled water to avoid exposure. According to Chelsea Langer, bureau chief for the state Health Department Environmental Health Epidemiology Bureau, "There are potential long-term health effects that can develop over several years if people continue to drink untreated water with these levels of metals."
