In 2014, the Serbian public was informed on several occasions about water supply
problems in the City of Užice. The reason behind the problem was the presence of potentially
toxic species Planktothrix rubescens (Cyanobacteria) in the waters of the Vrutci Reservoir (the
water supply intake for the City of Užice), the alternative water supply intake Sušičko Vrelo
and in the city distribution network. Although the measured concentration of hepatotoxic
microcystin-LR (< 0.01 μg/L) was considerably below World Health Organisation guidelines
for drinking water (1 μg/ L), the water was declared unsafe. The study presents and comments
on the results of physicochemical, microbiological and biological analyses of both raw water
samples collected from the water supply intakes and treated chlorinated drinking water samples
from the distribution network of the City of Užice water supply system.Tokom 2014. godine javnost Srbije je nekoliko puta obaveštavana o problemima
vodosnabdevanja grada Užica. Razlog je bilo prisustvo potencijalno toksične vrste
Planktothrix rubescens (Cyanobacteria) u vodi akumulacije Vrutci (vodozahvata grada
Užica), alternativnog vodozahvata Sušičkog vrela i u gradskoj distributivnoj mreži. Iako je
izmerena koncentracija hepatotokisčnog mikrocistina-LR (< 0,01 μg/L) bila znatno niža од
dozvoljene vrednosti propisane od strane Svetska zdravstveno organizacije (1 μg/L), voda je
proglašavana zdravstveno neispravnom. U radu su prikazani i komentarisani rezultati
fizičko-hemijskih, mikrobioloških i bioloških analiza sirove vode vodozahvata kao i
prečišćene i hlorisane vode za piće iz distributivne mreže gradskog vodovoda Užice
