Abstrtact
Groundwater quality was evaluated in Leningrad oblast and Southern Karelia in terms of their physicochemical characteristics and heavy metal concentrations. Estimates of groundwater quality indices revealed pollution levels from moderate to severe, high and extremely high groundwater toxicity in some regions, high risks of carcinogenic and non-carcinogenic effects. It was found that the largest effect on the quality of the examined groundwater is due to the concentrations of Fe, Mn, Ba, Zn, Ni, and Cd.
