Skład chemiczny i jakość wód czwartorzędowego piętra wodonośnego w rejonie rekultywowanego wyrobiska piasku podsadzkowego Maczki-Bór w świetle wyników badań monitoringowych

The paper presents the water quality of the Quaternary aquifer in the area of reclaimed open pit Maczki-Bór in the light of results of monitoring investigations carried out in 1995-2014. The area consists of mine workings, the reclaimed field of Bór Zachód, and the area of Bór Wschód, which is under reclamation. Processing and mining material from coal mines is mainly deposited in the mine excavations. In the northern part of the Bór Zachód field, there is a municipal waste dump for the Sosnowiec city. The monitoring network consists of 12 piezometers monitoring groundwater of the Quaternary aquifer, 3 monitoring points on the major dewatering canals, and 2 points on the Biała Przemsza River (upstream and downstream of the cumulative mine dewatering discharge). The monitoring of the leachate is carried out in 2 observation wells located in the deposited rock on the dumping ground of Bór Wschód. This article discusses the significantly spatially diverse chemistry and quality of groundwater and surface water affected by varied anthropopressure.
