The Government of Mexico City still does not know the substance found in the water of the Benito Juárez mayor's office. Pemex points out that these are degraded oils and lubricants that are undetectable in the first tests.

The lack of an answer has led residents to protest by closing Avenida Insurgentes, one of the busiest road arteries in the capital. Residents of the affected area will vote on June 2 for all public positions related to their municipality, from president of the Republic to local deputy, so a good part of the tension has focused on the friction between politicians and officials.. The Water System is cleaning the pipe network in the affected neighborhoods, as confirmed by Martí Batres, head of Government of Government. In any case, the smell has already started to go away, but the affected water has not yet been completely removed from the cisterns and water tanks, because the smell remains in several houses. The contamination of water in the Benito Juárez Mayor's office occurs in the middle of the electoral campaign.
