The paper presents the risks regarding the physical and chemical stability of the tailings ponds grouped under the name of Ds (D1, D2, D3, D4) located on the right bank of the river Cisla near the residential area of Baia Borşa and Colbu tailings pond upstream of the residential area of Borşa. The closure of these tailings ponds was done in a defective manner, without complying with the design and execution rules provided in the Technical Regulation on waste storage. The are two types of risks: first type, due to chemical instability that produces continuous acid drainage and the second type, regarding physical instability, due to erosion and extreme weather conditions which could lead to failure of the dams, with very serious consequences, causing material damages and loss of life. The risk of breaking the dams is even higher as it is located in the vicinity or upstream of residential areas located in a geographical structure of valley type containing the river Cisla with high debit.
