In Tlaxcala, Mexico, the Zahuapan River turned a reddish color due to suspected industrial discharges. The Procuraduría de Protección al Ambiente del Estado de Tlaxcala (PROPAET) inspected sewage networks in municipalities including Tlatempan, Atzitzimititlán, and Tizatlán.

Authorities identified a textile dyeing and washing facility as the likely source of the wastewater. Inspections revealed the establishment lacked required environmental documentation and a wastewater treatment plant. Consequently, PROPAET ordered a temporary suspension of the company’s activities. The facility faces potential fines of at least three million pesos. While the company’s name is being withheld for legal reasons, the local company Providencia Tlaxcala has stated it operates under a “Zero Industrial Water Discharge” scheme and utilizes its own treatment plant.
