Determination of Heavy Metal Concentration and Correlation Analysis of Turbidity: a Case Study of the Zlot Source (Bor, Serbia)

Karst aquifers are significant sources of water of the highest quality. Inaccessible and uninhabited karst areas are mostly away from urban centers and human activities. That is of crucial significance for karst groundwater quality. The discharge regime and karst water quality show the considerable rapid changeability of and dependence on the rainfall distribution and quantity in the catchment area. The purpose of this study is to show that there is no influence of anthropogenic factors on karst water by determining the heavy metal concentration in the water, the significance of monitoring karst water quality parameters, and to show how autocorrelation and cross-correlation analysis could be useful in defining the dependence rainfall–turbidity. The results presented in this paper refer to a case study of the Zlot Source (Bor, Serbia).
