Geological constraints on location of waste disposal sites in the Wielkopolska voivodeship.
A b s t r a c t . Areas preferred for location of waste disposal sites in the Wielkopolska voivodeship were determined on the basis of analyses of geological and environmental conditions, according to directives in Regulation of the Minister of Environment of 24th March 2003 on localization, construction, and liquidation for particular types of waste storage. Disposal possibilites of 3 fundamental types of wastes were defined: neutral (O), dangerous (N) and others (K). Crucial meaning for this classification have isolation properties and thicknesses of rocks in the subsurface zone (top not deeper than 2.5 m). The most favorable areas preferred to waste disposal sites are located in central and southern parts of Wielkopolska voivodeship and their distribution points out to the direct relation to geological framework, i.e., occurrence of the Variegated Clays Formation on the surface or in the near-surface zone. Natural geological barrier composed of these clays fulfills, in most of the cases, requirements for waster storage: other than dangerous and neutral (K), neutral (O), and, at the proper thickness, storage of dangerous waste (N). Resultant map showing distribution of the most suitable sites is a very useful material for making provincial and district waste management plans as well as for planning, determining, and searching the best sites for construction of new municipal disposal sites.
