Results of research works carried in two investigative areas are presented in the paper. The first was situated near Power Station and Mine “Turów” (Bogatynia, Działoszyn, Wolanów, Bratków). The second, presenting check group, was situated in central and northern districts of Zgorzelec administrative district (Jerzmanki, Sławnikowice, Łagów, Gronów, Jagodzin). In samples of water, collected for analysis, contents of iron, manganese, lead, cadmium, aluminium, arsenic, zinc, copper, chromium, physical and chemical parameters of groundwater quality such as pH, conductivity, ammonia, nitrates, nitrites, sulphates, phosphates, chlorides, total hardness was determined. It was not affirmed important differences in contents of mentioned components in samples of waters in both investigative areas. Criterion of metals contents allows to include samples of groundwaters for I or II class of quality. Exceptions presents contents of aluminium (III or IV class). Taking into consideration remaining physical and chemical parameters, general estimate of groundwater quality falls out considerably weakly. Samples of water locates in II, III and even V class (Jagodzin). It is caused by increased contents of nitrates, ammonia, manganese, aluminium and arsenic. For this reason samples of waters do not meets conditions for drinking water quality norm. ...
