Geochemical investigations of the soils in the vicinity of the river Zletovska

The basic task of this paper is to' obtain information according to which the degree of contamination to the soils with certain metals such as Fe, Mn, Pb, Zn, Cd, Cu, Cr, Ni, Co, As will be detennined along,. the Zletovica River flow by means of geochemical exploration. These explorations should serve for making a study about the environment within the great project for the construction of the watereconomy site Zletovica. The increased concentration of heavy metals in the samples of soil taken from the previously mentioned exploration wells at the both exploration profiles (I-II) is a potential danger for polluting the surface water flows of the rivers and the underground water that are in direct hydraulic relation to these water flows. Looking downstream, the surface water from the mentioned rivers empty into the Bregalnica River. It, along its flow, has formed alluvial detritus where a confined type of aquifer with free level was fonned. The city ofStip, as well as other inhabited places in the region, is being water supplied from such water aquifer. For getting a final conclusion about !he danger of pollution of great ground water quantities (aquifers) from local and regional aspect, it is necessary to carry out detailed hydrogeological and geochemical exploration works
