Abstract: This article covers the analysis of the impact of agricultural and municipal pollution on surface waters in a selected pilot section of the Dunajec River in Poland. The analysis was performed using the dynamic Water Quality Analysis Simulation Program (WASP) model. The operational use of the WASP allows the assessment of current and future changes in water quality and the planning of measures to reduce adverse impacts on surface waters. Based on the acquired and processed data, the model simulated the impact of the pollutant supply on the water quality in the selected section. The simulations were carried out in three developed scenarios. The results of the simulations of the spread of pollutants in the riverbed show that the adopted scenarios, including an increased supply of pollutants and unfavorable hydrological conditions, will not adversely affect the operation and efficiency of the water intake. Thus in the considered cases, the risk will not reach an unacceptable level. However, a serious threat may be caused by the failure of the sewage treatment plant located in the vicinity of a water intake. The conducted analyses indicate that the WASP may have significant application potential in the risk assessment for surface water intakes.
