A tractor-trailer with two tankers lost control and overturned around 16:00 hours on September 1 at kilometer 97.5 of the Ímuris-Cananea highway, approximately 15 kilometers from Cananea. [^1]

The Procuraduría Federal de Protección al Ambiente (Profepa) coordinated actions to evaluate and address an environmental emergency on the Ímuris-Cananea highway in the municipality of Cananea, Sonora, following a tanker truck accident. [^2]

A tanker truck accident on the Ímuris-Cananea highway in Sonora spilled approximately 12,000 liters of sulfuric acid onto the asphalt and surrounding soil. [^3]

The Federal Attorney for Environmental Protection (Profepa) imposed a temporary total closure on the area affected by the sulfuric acid spill on September 1. [^4]

Due to terrain conditions, some of the spilled material moved into hard-to-access zones, requiring further evaluation to determine the extent of environmental damage and establish remediation measures. [^5]

Preliminary estimates indicate that approximately 12,000 liters of sulfuric acid were spilled onto the asphalt and natural soil, with about 200 linear meters of soil affected. [^6]

Profepa and Semarnat stated that the spill happened around 16:00 hours on Tuesday. [^7]

The accident occurred at kilometer 97.5 of the Ímuris-Cananea road, approximately 15 kilometers from the municipality of Cananea, Sonora, when the driver lost control of the vehicle. [^8]

No injuries were reported in the accident, but Profepa will conduct a formal inspection to determine the magnitude of soil damage and establish remediation measures and administrative responsibilities. [^9]

The accident occurred at kilometer 97.5 of the Cananea-Ímuris highway around 4:00 PM on September 1, 2026, according to the Federal Attorney for Environmental Protection (Profepa). [^10]

The overturned tanker truck belonged to the logistics company Express Milac (Movimientos Industriales Logísticos de Alta Calidad) and was transporting sulfuric acid from a smelting plant in Nacozari to the Piedras Verdes mine. [^11]

Profepa ordered the responsible company to execute urgent measures including total containment of runoff using physical barriers and dikes. [^12]
