Abstract

The measurements of chemical components in water of Wieprza River showed that water of this river in 2002-2003 was characterised by the high purity. The average values of most indexes were con­tained in the ranges of standards for the first purity class. Nevertheless considerable increase of inves­tigation parameters was observed in zone of sewage-treatment plant and uncontrolled waste dump. The part of flow downing pollutions were absorbed by peat soils. Kępice town bring into Wieprza River the load of organic matter miscalculating to BOD5 average 133 kg 02 d-1 (85 t 02 y-1), the load of nitrogen 140 kg N d-1 (511N y-1) and phosphorus 18 kg P d"1 (6.21P y-1). However Wieprza River shows high self-purification ability. The level of investigation components in this river (4 km outside of the Kępice town) returned to the level which was 2 km before the town.


Key words: water, peat soil, river, chemical compositions
