ABSTRACT
In this study, heavy metal pollution and distribution on leachate and soil have detected with thesamples which were collected from the unregulated dumping site area in Eskisehir/Turkey. These samples wereanalyzed for pH, cadmium, copper, iron, lead, nickel and zinc in spring, summer and autumn seasons. Thesampling points were marked on an air photograph by using GeoMedia Professional 6.0 softw are. Analysisresults obtained from the sampling points were interpolated by using SURFER 7.0 software and distributionmaps were performed. These maps w ere reregistered by using GeoMedia Professional 6.0 and compared withthe air photograph and geological units. As a result, it was seen that heavy metal concentrations were increasingtowards to agricultural areas in the northeast of the dumping site. When physical-chemical analysis results andfindings obtained from GIS are evaluated with together, it is said that the EskiÕehir dumping site is going tocause environmental and ecological problems in both short and long term and this site should be urgentlyrehabilitated.
