Contents of Cd and Pb as well as C-6-C-12, C-12-C-35 hydrocarbon fractions and aromatic hydrocarbons in groundwater samples, taken from 4 boreholes, were detd. using at. emission spectrometry with excitation in induced plasma and gas chromatog., resp. Based on the anal. results, the quality classes of the tested water samples were detd. in accordance with sp. national legal regulations. Water samples from 2 drilling holes were highly polluted and addnl. technol. boreholes for pumping the polluted water, water treatment stations, pump systems as well as multifunctional boreholes for ventilation, aeration and biopreparations were recommended to protect the environment.
