ASSESSMENT OF POLLUTION AND ENVIRONMENTAL RISK OF MINE ACID WATERS FROM CONTAMINATED MINING SITES ON SURFACE WATERS IN THE BRAD PERIMETER

From contaminated mining areas, contaminants can migrate to different components of the environment, being favored by physicochemical transfer mechanisms such as their transfer into water. The dispersion of metallic contaminants from closed mining sites in surface waters is favored by the topography...

Summary:From contaminated mining areas, contaminants can migrate to different components of the environment, being favored by physicochemical transfer mechanisms such as their transfer into water. The dispersion of metallic contaminants from closed mining sites in surface waters is favored by the topography, climate and lithology of the area. In the Brad mining area, activity has ceased for about 15 years. Properly unnamed tailings and coastal galleries are a diffuse source of surface water pollution. The paper aims to assess the degree of pollution and the environmental risk due to mine acid waters on surface waters.
