The Hudinja rises in the southern part of Pohorje and is part of the Savinja river basin, which
is a sub-basin of the Sava river. Its catchment area extends over eleven municipalities.
Downstream, it receives a large amount of sewage from households and industry, as well as
pollution from leaching from agricultural land, which has a significant impact on its water
quality. In my thesis I analysed the results of measurements carried out by the Slovenian
Environment Agency for selected parameters reflecting the quality of the watercourse. The
measurements have been carried out at two monitoring sites since 2007 and show that the
water quality of the Hudinja River has not changed significantly over time, while at the same
time it is deteriorating due to downstream pressures. Sulphate is an important parameter,
with values well above the expected natural background levels, most likely due to industrial
effluents.
