Physical, chemical and mineralogical properties of soil in municipal dumping site at Barycza were studied to evaluate the soil as a layer sealing natural substratum and slopes of the dump. The dusty soil of specific density 2.71 g/cu. cm, bulk density 1.95 g/cu. cm, plasticity index 0.29-0.67 and 18.44-25.58% moisture content, filtration coefficient from 1.37x10*[-3) to 9.96x10*[-8) cm/s, contained clayey minerals, mainly illite, quartz, carbonates, hygroscopic water and a bit of organic matter. Also the content of CaCO3 was stated at pH 6.8-7.2. Examined subsoil was an effective isolating layer for the dump
