ZERO STATE OF SURFACE WATER QUALITY IN THE AREA OF THE PLANNED BANJA LUKA-PRIJEDOR MOTORWAY

Abstract

The target location of the Banja Luka-Prijedor motorway alignment is situated in the western Republic of Srpska and belongs to the northern axis of development, which is the belt of the most intensive economic and social activity. Before starting the construction, it is necessary to determine the state of surface water pollution, that is to say the zero state, in order to later have a pragmatic idea of the impact of traffic on the quality of surface water during the motorway operation. The paper presents the results of surface water analysis, which will be the basis for further assessment of possible changes in quality when the highway is put into operation. In order to provide a detailed analysis of the existing surface water quality in the investigated corridor of the future motorway, the physical-chemical parameters of the Kozaračka River and the Luščica River were analyzed. The obtained results show that the water quality of these watercourses in relation to certain parameters ranges from the first to the fourth class of water quality.
