Mining Complex

The Sancho Dam was built in 1962 and is fed by the Meca River, which receives water from subsidiary tributaries affected by acid mine drainage (AMD), mostly generated by the abandoned Tharsis mining complex. This study focuses on the hydrochemical relations observed between the water at the entrance of the reservoir and a point located further away, specifically at the dam. The main aim is to analyze the water parameters in both monitored points, in order to evaluate possible attenuation processes and to propose a spatial evolution model of the pollutants' load by using cross-correlation functions. Concentrations of metals and sulfates put in evidence their contamination by acid mine drainage, with greater pollution load at the entrance of the reservoir than in the dam, due to the reduction of the same in the course between the two points. This attenuation results from the precipitation of iron oxyhydroxysulfates produced by the increase in the pH as well as by dilution and sorption phenomena. The cross-correlation functions show the close relationship between the two sampling points with a transit time of contaminants less than 1 week (t = 0) for most cases, due to the small distance between the two points (about 300 meters).

This paper addresses the modelling of the processes associated with acid mine drainage affecting the Trimpancho River basin, chosen for this purpose because of its location and paradigmatic hydrological, geological, mining and environmental contexts. By using physical-chemical indicators it is possible to define the contamination degree of the system from the perspective of an entire river basin, due to its reduced dimension. This allows an exhaustive monitoring of the study area, considering the particularity that the stream flows directly into a water dam used for human supply. With such a perspective, and in order to find global solutions, the present study seeks to develop methodologies and tools for expeditious and accurate diagnosis of the pollution level of the affected stream that feeds the water reservoir. The implemented methodology can be applied to other water systems affected by similar problems, while the results will contribute to the development of the state of the art in a representative basin of the Iberian Pyrite Belt, whose pollutants' contributions are incorporated into the reservoir.
