At present the evaluation of WWTP effectiveness is based upon organic matter and nutrients removal. Recently it was found out that sewage treatment leads to formation of resistant to biochemical degradation organic compounds, similar to humic acids. The humic acids formed during sewage treatment process play diversified functions when discharged to surface waters - for instance they can act as carriers of hydrophobic organic pollutants or heavy metals. The aim of the study quantitative and qualitative analysis of formed humic acids depending on the sewage treatment technology. The investigations were performed at three conventional WWTPs and two constructed wetlands. On the basis of investigation results it can be stated that humic acids from conventional and natural WWTPs effluents may have various functions in the environment
