The aim of the study was a preliminary examination on water quality (U01-U08) in Rasina area, through the standard physico-chemical parameters: temperature, pH, conductivity, turbidity and total organic matter. All samples were odorless and tasteless. The results for temperature, pH and conductivity were within the values defined by Regulation on the quality of drinking water, except for the pH value of the sample U05. Increased turbidity was observed in the sample U03 (13.5 NTU). On the basis of the results for total organic matter (1.2 to 5.5 mg O2/L) that were within the permissible range, it can be concluded that all the studied samples belong to the first (I) class water quality.Cilj rada bio je preliminarno ispitivanje kvaliteta voda sa područja Rasinskog okruga (U01-U08) određivanjem standardnih fizičko-hemijskih parametara: temperature, pH-vrednosti, provodljivost, mutnoće i ukupne organske materije. Svi uzorci su bili bez mirisa i ukusa. Dobijeni rezultati za temperaturu, pH i provodljivost bili su u okviru vrednosti predviđenih Pravilnikom o kvalitetu vode za piće, osim pH vrednost uzorka U05. Povišena mutnoća zabeležena je u uzorku U03 (13,5 NTU). Na osnovu vrednosti za ukupne organske materije (1,2-5,5 mg O2/L) koje su bile u granicama dozvoljenih može se zaključiti da svi ispitivani uzorci pripadaju vodama prve (I) klase kvaliteta
