In contradiction to classical interpolation methods geostatistical solution takes into consideration the degree of correlation between the values of samples in certain area, as functions of distance and direction between samples. For the modeling of solid wastes in Košice were used the data from 35 stations from different parts of the town. The resulting model is the map of isolines where we can establish 2 main types of pollution sources, as well as to follow the direction and extent of pollution in the town. The complementary result is the map of isolines of deviation of estimate expressing the distribution of reliability of estimated values that may be used as a base for optimization of the network of the sites of sample collection. Geostatistics may be used in solution of the most particular environmental problems, e. g. distribution of the elements of heavy metal in soil or extension of radioactive fall in space etc.
