The data referring to the water quality in a small river including pH, the river flow rate and the concentrations of Fe3+, Cu2+, Mn2+, SO42- and NO3- is obtained. The influence of the rainfall and snowfall on the surface water pollution is analysed and discussed. Polynomial models of the river flow rate and water pollutants emission are offered. They can be applied to control the water treatment plant operation.enArticle
