PMV Minera diesel spill in Jáltipan

In October 2026, Mexican environmental authorities ordered a partial and temporary closure of PMV Minera facilities in Jáltipan after a diesel spill contaminated the Chacalapa stream. The spill originated from a brine extraction well at the company’s salt plant when rainfall washed diesel into a nearby water body. Profepa mandated urgent corrective measures, including well repairs and an environmental remediation program. Authorities confirmed the spill did not originate from Pemex infrastructure.

By November 2026, changing weather conditions caused diesel vapors from the previous incident to concentrate and drift toward residential and educational areas. This led to the preventive evacuation of several schools in Jáltipan due to strong chemical odors. While the odors eventually dissipated and preventive measures were lifted, local residents expressed ongoing concern regarding lingering fuel residues near the industrial complex.
