Contamination assessment of Krakow Valleys Landscape Park’s surface and wastewaters

Abstract

This research consisted of a physico-chemical evaluation of the streams and wastewaters within Krakow Valleys Landscape Parkin the Kluczwody, Bolechowicka, Będkowska and Kobylańska valleys. The following set of parameters were determined in the samples: pH, Eh, conductivity, oxygen content, concentration of metals' cations and selected anions. The results revealed that the wastewaters discharged as well as the streams that feed into the Rudawa river are mainly polluted with nitrates. Additionally, the examined wastewaters contained a high concentration of phosphate exceeding class II purity maximum permissible values.
