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

This research consisted of a physico-chemical evaluation of the streams and wastewaters within Krakow Valleys Landscape Park in the Kluczwody, Bolechowicka, Bedkowska  and Kobylanska 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.
