Abstract:
Groundwater is an important source of drinking water supply throughout the world. In recent decades, the demand for fresh water has increased greatly due to the accelerated population growth and the development of the industry. The environmental heavy metals pollution is consider to be a global concern due to their persistence, toxicity, bioaccumulation and non-biodegradability. The pollution of groundwater with metals is produce by anthropogenic sources such as metallurgy, melting, mining, galvanic processes, traffic and also as result of geological background. Cu, Mn, Ni, Zn are micronutrients which are essential for living organisms, but over a certain concentration they become toxic. Heavy metals such as As, Cd, Cr and Pb are toxic to living organisms regardless of concentration. In order to prevent the chemical pollution with metals, drinking water quality assessment must be performed. Pollution indices regarding metal concentrations are significant tools in monitoring process and have been successfully applied all over the world.
