[VD12] Chemical state of the rivers
State

Key message
Neutral

Good chemical status is determined for almost 95% of surface water bodies, and poor chemical status for seven water bodies - Sava near Vrhovo due to mercury, Krka near Otočec and marine water bodies due to tributyltin compounds. In general, Slovenian surface waters are not burdened with priority or preferably hazardous substances.

Good ecological condition or. 59 (38.1%) surface water bodies do not reach good ecological potential. Of these, the water bodies Kamniška Bistrica Študa - Dol and Cerkniščica are classified in very poor condition.
