Geochemical properties of the waters of the river Bregalnica

The paper presents the results of the geochemical properties of the waters of the River Bregalnica obtained after continuing monitoring of the water quality and the determination of the major parameters such as the concentration of heavy and toxic metals, organic pollutants and nutrient concentrations as well as the concentrations of cyanides, detergents etc. The quality of the water of the River Bregalnica is unstable. The number of organic pollutants rises permanently and, like in other regions in Europe, the discharge ofwaste materials into the river is enormous. The concentrations of heavy and toxic metals are within the levels allowed except for arsenic and manganese that yielded increased amounts
