The article reports on the results of analytical water sample indicators research of three underground springs in the Birsk region of Bashkortostan Republic: “Dvenadtsat' klyuchei”, “Berezovyi klyuch”, “Vinnyi klyuch” i “Il'in klyuch”. The article gives the organoleptic rate of water quality, describes the research results of its general mineralization, hardness and its cationic and anionic composition, organic substance content, radiological and microbiological indicators. The authors point out that the numerical values of water quality indicators as a whole are not more than the normal standardized ones to be used for household and drinking purposes. The average value of radioactivity volume in the water of “Dvenadtsat' klyuchei” and “Berezovyi klyuch” is a little more than the standard of interference in drinking water. The water of springs under investigation and discussion satisfies the San PiN (Sanitary-epidemiological Rules and Norms) requirements 2.1.4.1175-02. and may be used as drinking water.
