Cause for Water Contamination in Mexico City Still Undetermined

Residents of the Benito Juarez municipality in Mexico City raised concerns about foul odors emanating from their water several weeks ago. Following extensive testing, the government of Mexico City confirmed this week that the water reaching homes in 10 neighborhoods contained a mixture of oils and degraded components, indicating contamination from the oils and lubricants family. However, the cause of the contamination remains undetermined.

Javier Emiliano González, Director General, PEMEX Logistics, stated that detailed studies revealed a very low concentration of oil compounds in the water, initially undetectable in preliminary tests. Despite conducting thorough inspections on the nearby pipeline, PEMEX found no cracks, leaks, or unauthorized connections.

Martí Batres, Mexico City’s Mayor, assured that the water issue does not pose serious health risks. He advised residents to use bottled water for drinking, cooking, and personal hygiene, restricting contaminated water to non-consumable purposes like cleaning.

Although the low concentration of contaminants may cause skin irritation, particularly in sensitive individuals or those with allergies, Batres emphasized that it does not pose a significant health risk. He confirmed the closure of the Alfonso XIII Well, the suspected source of contamination, ensuring that the affected water is no longer distributed to any neighborhood.

While reports of the smell have diminished in some homes, residual contamination in pipes and cisterns may persist in others. Batres, along with officials from SACMEX and Civil Protection, disclosed that extensive testing of water samples revealed no additional elements compromising the overall quality of the city's water supply.
