IMPACT OF THE CONSTRUCTION SITE OF A PART OF THE BANJA LUKA – DOBOJ MOTORWAY ON THE QUALITY OF WATER IN THE RIVERS VRBAS AND CRKVENA

Abstract

The paper presents the impact of the construction site of a part of the Banja Luka – Doboj motorway,
section 1: Banja Luka – Prnjavor, in the settlement of Miloševac, on the quality of water in the rivers
Vrbas and Crkvena. Before the construction of a new bridge, the zero state was determined in the direct
vicinity and at locations downstream from the construction site in order to have a realistic picture of
impacts of the mentioned construction on the quality of surface waters. Comparison of the data acquired
by continual monitoring of a significant number of parameters (total 18) during 12 months and their
zero state, i.e. their values before the commencement of construction, gives a realistic overview of
impacts of the construction site on the quality of water in nearby surface watercourses. In the case that
the execution of civil works proves to have a negative impact on the quality of these rivers, the cause of
negative impacts shall be determined and additional measures of prevention, reduction or mitigation of
impacts shall be taken.
