The paper presents the results and conclusions from the investigations carried out on the water contamination with heavy metals in the River Kalnistanska and its vicinity. For the increased content of heavy and toxic metals in the near vicinity of river Kalnistanska, especially in the water systems, large contribution have increased ore mineralization of the area, sewage waters from the feces of the town and neighboring villages, and industrial objects (battery factory etc.).The examinations are an attempt to determine the real and the physical state of heavy metals in the river water and its tributaries. Samples were analyzed with ICP-AES method. Earlier experiences indicated that the following elements should be expected: Mn, Fe, Al, Zn, As, Cd, Cu, Ni, Co, Ag, Cr, Ti with possible occurrence of increased concentrations of maximum allowable amounts. Analysis and data interpretation yielded increased concentrations of Mn, Fe, Al, Pb, Zn, As, Cd and Cu. The entire drainage system in the Kalnistanska in the Municipality of Probistip has been polluted. It was found that the major pollutants are the Zletovo Mine and the discharge of waste waters containing heavy metals.
