Impact assessment of point and non-point sources of water pollution on a small urban stream

Popis výsledku v původním jazyce

The paper presents a study of the impact assessment of point and non-point pollution sources on a small urban stream, the Botic creek, which flows through rural as well as urban area. The monitoring was focused on basic physical and chemical quality of water, heavy metals concentrations in water as well as bed sediment and on hydroecological assessment. Both, non-point as well as point sources impact were identified. The most significant pollutants are nutrients originating from non-point sources (farming), which increase concentrations of N and P compounds in the section of the creek in rural area. As the main point source of heavy metals in bed sediment of the stream, road traffic was identified, though some characteristics of aquatic environment (reduction conditions given by eutrophication) can support remobilization from sediments and increase of metals concentrations in water in sampling sites unaffected by road traffic. Also morphological changes of the stream channel were identified resulting from urban drainage as a set of point sources, which makes an achieving of at least good ecological status impossible.
