Abstract: DOI: 10.24193/subbambientum.2021.02 Published Online: 2022-10-30 Published Print: 2022-11-30 pp. 19-31 VIEW PDF FULL PDF Mining areas are among the most polluted industrial sites, the surface waters being often affected by acid rock drainage. Mine and processing wastes represents one of the main sources of acidic waters. The seepages form Bloaja tailings management facilities have a low pH and increased total dissolved solids. Chemical analyses show high Zn, Cu and Pb concentrations of the contact water with the pyrite concentrate deposited on Bloaja Old tailings management facility. These polluted waters are discharged in the watercourses, decreasing the quality of surface water. Despite of the remediation of Bloaja New tailings management facility, the waste waters seepages have a conspicuous environmental impact on watercourses from Lăpuș River basin. Keywords: mining area, tailings, acid rock drainage, pyrite concentrate, heavy metals, water pollution. |
