Our study was conducted in the area of the Parseta and Radew rivers in 2012 and 2013. Samples were taken of water and bottom sediments. In terms of their physico-chemical composition, the tested waters can be characterized as slightly polluted. In terms of zinc and copper concentrations, the waters belong to purity class I, but the contents of cadmium, lead, and nickel exceed the Proposed Environmental Quality Standards for Priority Substances. As far as copper, nickel, zinc, and cadmium are concerned, the studied sediments were not polluted, and the geo-chemical index values were within class I. The relevant accumulation rates for metals in sediments can be ordered as follows: Cd
