摘要：

The rupture of the Córrego do Feijão iron mine Tailings Dam I killed at least 260 people and had major environmental and social impacts. We analyzed the chemical compounds dissolved in the surface water and the bottom sediments of Ferro-Carvão Creek, the watercourse directly affected by the disaster, and at points upstream and downstream of its confluence with Paraobeba River, the main watercourse of the region. We also analyzed samples of the released tailings and groundwater near the area directly affected. From an environmental geochemistry standpoint, the water analyses suggest that the water quality degradation was not as catastrophic as the human and material losses and damage to biota. The groundwater samples did not present disconformities according to the Brazilian Environmental Council (CONAMA). In fact, most of the surface water samples that exceeded the maximum allowed concentrations were upstream of the affected basin. This suggests that mining industry sources other than those associated with the disaster had damaged its water quality before the event. Thus, previous knowledge must be used to evaluate the real anthropic impact in events of this nature. It can also be an excellent tool to guide remediation in situations such as in the Córrego do Feijão Iron Mine disaster. © 2023, The Author(s) under exclusive licence to International Mine Water Association.
