ADUVIRE, Osvaldo  y  ADUVIRE, Hugo. Diagnosis and rehabilitation of manifests affected by mining environmental waste. REV. MAMYM [online]. 2021, vol.6, n.1, pp.17-25. ISSN 2519-5352.

Abstract The wetlands as well as most of the high Andean ecosystems are subject to anthropic and / or natural pressures, the rehabilitation of these ecological ecosystems is usually expensive, especially when engineering works are required. These actions represent a high level of risk since it is necessary to guarantee the implantation of plant formations that are established in an edaphic environment, mainly organic, characterized by a permanent water saturation condition, presenting a great biological diversity with respect to the environment. This paper presents the rehabilitation and recovery works of areas that were affected by discharges from old mining works and natural contributions due to the presence of mineralized veins of sulfides and coal that outcrop to the surface. To undertake the rehabilitation work, a detailed diagnosis of the site was carried out (climatic, geological, hydrological characteristics, characterization and determination of the quality of the soil, detailed description of the ecological, floristic and agrostological characteristics of the affected wetland). As well as, the content of organic matter that comes from plant remains (roots, leaves, etc.), organisms and microorganisms typical of wetlands, which are in the process of decomposition, with high carbon content. With the information collected, improvement and recovery actions are proposed, ranging from engineering work to preparing stable surfaces and achieving spaces and conditions of humid areas composed of islets or blocks placed in the shape of cushions and constituted by vegetation formations properly of wetland and its edaphic support formed by peat and organic matter, surrounded by perimeter and interior channels that maintained the flood levels in the rehabilitated areas, to achieve the biological and hydrological integrity and the stability of the recovered wetland system.
