Hydrochemical analyses of the Szabasówka river were conducted in 2009. Determined were 18 selected physicochemical indices of the surface water at ten dates from two measurement-control points. Analysis of results revealed that in the upper river in Łaziska village, two indices: total suspended solids and dissolved oxygen content classified the water to II purity class, whereas four indices classified the water to the same class in Mniszek locality (point 2). The other indices classified the water to I purity class. Investigations of utility values of the Szabasówka river revealed that in point 1 its water cannot be used for for domestic water supply because of high concentration of total suspended solids. Along the whole analysed stretch, water did not meet the requirements for a natural habitat of the Salmonids because of high temperature and low content of dissolved oxygen. Cyprinids have adequate environmental conditions only in point 2.
