Abstract


METALS AND METALLOIDS IN WATER FROM MUNICIPAL WELLS AND TAP WATER IN THE AREA OF RACIBÓRZ

Abstract. Paper describes results of investigation on metals and metalloids concentrations in water from well fields and consumers’ tap water in Racibórz. Concentrations above the maximum admissible level (MAL) were found for iron, manganese and lead in groundwater from municipal wells supplying citizens. Treatment processes lower elevated concentrations of investigated constituents below the MAL successfully. Concentrations of almost all investigated elements in tap water show increased maximum values with respect to water after treatment. In case of iron, nickel and lead, concentrations exceeding MAL were detected. Authors analyzed influence of different factors on occurrence of increased values of metals and metalloids in tap water. It was estimated that exposure of the consumers to iron is low and to nickel and lead is very low. Conclusions on measures to be taken to improve the drinking water quality in the area of Racibórz were presented.
