Our recent investigation in Cerro de Pasco reveals 11 violations of water protection law
Source International's recent research has focused on the environmental quality of river water and sediments in the Simón Bolívar district to monitor mining activities’ impacts over the years.
The environmental study is the sixth of a series of independent environmental monitoring carried out since 2009 to inform the population and local and national institutions about the state of natural resources quality in the region of Pasco.
The investigation has shown 11 violations of Peruvian regulations on environmental protection in water resources within the Simon Bolivar district.
Highly toxic metals such as lead, manganese, zinc and iron have been recorded in the Tingo river and Ragra river. At the same time, molybdenum has been observed in water for human consumption in concentrations higher than national standards. Additionally, concerning levels of lead, arsenic, cadmium, chromium, lead and zinc were recorded in sediment sample in the Ragra river at concentrations above international standards.
Within the Simón Bolívar district, the Ragra and the Tingo rivers constitute the water resources most impacted by mining activities. The Ragra river, a tributary of the San Juan river, is being affected by the leachates and effluents generated by the mining companies, such as the mines, tailings dams, and exploitation activities and concentration. It is urgent to intervene to reduce the risk of toxicity throughout the food chain, considering that the San Juan river feeds the Junin Lagoon, a national reserve recognized as a wetland and, flowing into the neighboring Junin province, transporting pollution to this agricultural production area.
Based on the results discussed in this study, Source International recommends prioritizing environmental remediation actions and closing the mining operations to limit environmental pollution and reduce health risk to residents exposed to toxic and carcinogenic substances at very serious levels for the human health.
We have shared the report with local authorities in the last few days to demand urgent action.
We plan to share the main results during an online webinar in the upcoming weeks.
We are also programming our next mission to Pasco to proceed with our campaign.
