A disturbing discovery has unraveled the troubling issue of hazardous waste management along the US-Mexico border. An investigation by The Update Desk has revealed the alarming presence of thousands of white bags containing potentially toxic materials near the city of Monterrey, Nuevo León, Mexico.
The story began with the “mystery of the white bags” – piles of industrial sacks found sprawling across acres of land near Monterrey. Mexican authorities ordered their urgent removal, but aerial footage has now exposed an even more extensive problem.
The bags are linked to a company called Zinc Nacional, which recycles toxic dust imported from the US steel industry. According to the latest imagery, the company has cleared the bags from its main plant, but they have now been found at another site owned by a Zinc Nacional subsidiary, Meremex, covering over an acre of land.
Toxicologist Martín Soto Jiménez from the National Autonomous University of Mexico has conducted soil sampling in the neighborhoods around the Zinc Nacional plant, finding high levels of lead, cadmium, and arsenic – even inside some homes and schools.
The company has disputed the findings, claiming the study was flawed and that many of the results were not “alarming.” However, environmental experts have expressed grave concerns about the sheer volume of hazardous materials accumulating around the plant’s properties.
James Rybarczyk, a retired chemistry professor who has been investigating Zinc Nacional’s activities, questions why such a large quantity of materials is being stored rather than sold. “That’s an enormous quantity of anything – and to just be sitting there?” he said.
The three sites in the industrial park where Meremex is located are in the watershed of the Pesquería River, which flows into the Rio Grande, raising concerns about potential groundwater contamination. Mexican environmental attorney Francisco Javier Camarena Juárez has called for stricter oversight of the situation.
Regulators have ordered Zinc Nacional to sample the underlying soil and develop a remediation plan for any contamination. However, some experts argue that the company should not be allowed to hire its own investigators, as this could be a conflict of interest. Instead, they suggest the community should demand an independent study, similar to what was done in the case of a notorious lead smelter in Torreón, northern Mexico.
This troubling case highlights the broader issue of hazardous waste management along the US-Mexico border, where the export of toxic materials from the US to its southern neighbor has become a contentious topic. As the investigation unfolds, the people of Monterrey and the surrounding region await answers and action to address this growing environmental crisis.
