This article presents a case of reclamation of excavations after exploitation of gravel located in the Vistula River near Oswiecim. Gravel deposits are located there shallowly below the surface and they are associated with river accumulation. This area is characterized by a very high level of groundwater vulnerability. After depletion of the gravel field, the excavations are liquidated by backfilling with waste, usually mine waste. The material to be used underwent a formal assessment of its impact on the aquatic ...

The paper describes the case of excavation reclamation after exploitation of gravel, located in the Sola River valley in Rajsko, in the range of the Nature 2000 area Lower Sola Valley (PLB120004), within and the vicinity of the Nature 2000 area of Lower Sola (PLH120083), the vicinity of breeding ponds. There is a Quaternary aquifer in the excavation bottom. 540,000 tonnes of waste from a nearby hard coal mine were used for ground works, which filled the excavation after exploitation of gravel. As a part of the fie...

Underground mining exploitation in the Upper Silesian Coal Basin results in lowering of a land surface. It has its environmental consequences. These processes favor the creation of wetlands and floodplains, which often help to increase biodiversity. However, progressive lowering of the land surface disrupts flow of rivers, force change of land use, and may lead to real risks for building facilities. Therefore, it is necessary to undertake reclamation works, which consist in filling depression area. All this leads ...

Roads and highways provide a linear source of environmental (air, surface water, groundwater) pollution. This influence depends on the road class, the traffic intensity and the accompanying infrastructure. These factors are the basis for determining the groundwater vulnerability in the vicinity of roads. Road investments are intensively developing in the countries of Central and Eastern Europe, including Poland. 2350 km of new expressways and highways have been built in the period of 2005-2016 in Poland.
