Defined are the physicochemical properties of three mountain spring waters in the area of Vasiliovska mountain, Municipality of Teteven, Bulgaria. Vasiliovska mountain is in the central part of Stara Planina (Balkan) mountain.
The methodology is including research of physicochemical parameters and microbiological indicators. It is needed the whole parameters to corresponds to Ordinance № 9 / 2001, Official State Gazette, issue 30, and decree № 178 / 23.07.2004 about the quality of water, intended for drinking purposes in Bulgaria, European Union [1,2,3].
The spring waters from the given three water sources are characterized by microbiological indicators, and the pathogenic micro-organisms in the samples from the springs water sources mentioned above are determined by the membrane method [4,5].
It is shown that according to 18 controlled parameters included in the study, the following springs in Vasiliovska mountain - “Babintsi” with water temperature 12.3°C, “Gechovoto” with water temperature 13.5°C, “Ignatov izvor” with water temperature 14.1°C, correspond to all controlled parameters according to Ordinance № 9 / 2001, Official State Gazette, issue 30, and decree № 178 / 23.07.2004 about the quality of water, intended for drinking purposes.
