Abstract
Aiming to determine the possibilities for pollution of the underground waters accumulated in the alluvial sediments of the river Bregalnica, with the investigations in this project analysis of the geological - hydrogeological data from the investigations made for water supply of the municipalities Stip, Kocani, Delcevo and Berovo were performed. According to this data structural - lithological data and hydrogeologycal characteristics of the water bearing alluvial gravels and sands and to their roof sediments.
In all analysed regions, alluvial sediments have similar structural - lithological composition and they presented double layer porous medium with two layers with different granulometric and filtration characteristics. Lower layer presents rough porous water bearing medium composed of gravel - sand series and locally with small parts of clay. Above the water bearing layer there are overlay sediments presented by dusty sands, clayey dusty sands and sandy clays with variable thickness. This layer is characterized with fine grained porosity and poor filtration characteristics.
According the data from the experimental pumping of the exploitation wells, as well as the data from the granulometric analyses, filtration characteristics of the water bearing gravels and sands were determined. Samples taken from the overlay sediments were analysed and filtaration parameters for these sediments were determined.
According the hydrogeological characteristics of the alluvial sediments, maps for the pollution sensitivity were made.
Investigations show that alluvial sediments of the river Bregalnica belong to the regions that are very sensitive to pollution.
Registration of active and potential anthropogenic pollutants of the water of the river Bregalnica and of the underground waters accumulated in alluvial sediments was done.
Protection measures for protection of the water of the river Bregalnica and of the underground waters in the alluvial sediments were proposed.
