Resumen

The Murcia Region in Spain has significant environmental issues caused by its mining history, particularly in the Cartagena-La Union region. This area has about eighty abandoned mine tailings dumps, which pose severe environmental risks, such as soil and groundwater contamination and adverse effects on flora, fauna, and human health. Among these deposits, “El Lirio” in the Coto Ponce area has a significant volume of stored mine tailings, mainly containing sulfide mineral residues such as pyrite, sphalerite, and galena. Geophysical and geotechnical techniques are employed to assess the current state of the hazardous deposits and characterize them before and after restoration to address these challenges. These methods provide detailed information on the composition, structure, and spatial distribution of materials within the reservoir, which is vital for formulating effective remediation strategies. These strategies aim to minimize environmental impact and facilitate ecosystem recovery in the affected areas.
