Abstract

ALTERATION OF GROUND- AND SURFACE WATER QUALITY RESULTED FROM THE CONTACT OF INFILTRATION AND FLOOD WATERS WITH THE EMBANKMENT MADE OF RE-DISPOSED COAL MINING WASTESAbstract. An impact of civil engineering constructions made of coal mining wastes on ground- and surface waters in their vicinity was exemplified in the embankment of the Bukow flood polder at the Odra River. Observations of water status alterations in the area within the local ground- and surface water monitoring network proved that the embankments constructed of re-disposed material exerted s strong adverse impact on the ground and surface water quality, mostly due to release of two major constituents that are sulfates and to the lesser extent chlorides, as well as of iron and manganese ions being products of sulfide decomposition.
