Abstract

The article assesses the impact of natural and anthropogenic factors on the quality of surface water grasped by Krakow's water treatment plants. We analyzed the indicators chosen in the physicochemical marked in the raw water in the years 2007–2014. The study shows that the water prior to treatment differed in the number and share of separate factors. These components, in turn, explained 63% to 71% of analyzed chemical composition of water.
