Abstract
One of the main river water quality and environmental problems in Lithuania is pollution with biogenic and organic substances. Urban
wastewater and diffuse source pollution from agricultural areas are the main sources of river water pollution with biogenic substances.
Hydrochemical indicators of tendencies of change for the period of 1992–2010 were analyzed as well as the change of point pollution for
the period of 2000–2010. The study included a field study, assessing the impact of point pollution in Šilutė town on the river Šyša water
quality. The FYRIS model estimated the change in the impact of general nitrogen on the river Šyša diffuse and point water pollution for
the period of 1997–2006. Statistical correlations between the observed concentrations in the water quality and those modelled were made.
Keywords: water quality; surface water; modelling; biogenic substances.
