Sažetak
Carbonate rock aquifers are composed of water-soluble rocks where fractures can be widespread by karsting to sinkholes, caves or tunnels causing that water and any ` accompanying pollutants move very rapidly. Therefore, groundwater is very susceptible to pollution in karst areas. Even some heavy metals can migrate to the considerable distances through karst channels despite of the buffering capacity of surrounding carbonates. Soils are often the only cover of the carbonate rocks and in that case, the thickness, permeability and sorption properties of the soil control the migration velocity of contaminants. Under certain conditions, fine-grained soils could prevent an accidental groundwater contamination leaving time for remedial action. An international research project was started in summer 2000 in order to investigate the permeability and sorption properties of fine-grained soils in karst areas of Brezovske ltarpaty Mts. and Slovensky Kras (Slovakia) and Istrian Peninsula (Croatia). It is an interdisciplinary attempt to the characterisation of the Quaternary soil cover in karst areas. Pedological, mineralogical, engineering-geological, and geochemical methods were used to obtain complex information of some typical soil types of estimated areas. In order to observe changes in the soil properties due to contamination or other recognised anthropization, soils from both uncontaminated sites and sites affected by different source of pollution were investigated. Contamination sources were agriculture (fields and vineyard), road traffic and a coal power station. A very first assessment of the function of studied soils as pollution barriers will be presented at the workshop, when permeability tests, as well as all sequential analyses are finished and all morphological and chemical data collected and interpreted. Anthropization impact will be discussed in order to foster soil conservation and groundwater protection. This work was supported by the Research Support Scheme of the Open Society Supporting Foundation, grant No.: 1326/2000.
