The aim of the study was ecological monitoring of the natural waters in Stara Zagora Region, Bulgaria, ascertaining seasonal concentration variations during 2010, establishing of a database and correlations regarding the parameters – total hardness, Ca2+ and Mg2+ concentrations, providing a framework for sustainable management of the natural waters in the region. To accomplish this goal, the values of the three indices in real surface and groundwater samples taken from four municipalities of Stara Zagora Region - Chirpan, Kazanlak, Gurkovo and Stara Zagora were spectrophotometrically determined and the statistical significance of the data was tested. The highest average Ca2+ concentrations were registered in Chirpan - 100.86 – 155.50 mg L–1 and Zetyovo Reservoir - 101.19 – 185.50 mg L–1 waters, Chirpan Municipality, during the four year seasons. The surface and groundwaters in Gurkovo and Kazanlak Municipalities suited the quality requirements for surface, groundwaters and waters intended for human consumption according to the three parameters studied. The groundwaters in Stara Zagora Municipality - Kolyo Ganchevo-well; Sulitsa Village-well characterized with exceeded TH values and Ca2+ concentrations. The ecological monitoring conducted ascertained that the natural waters from all analyzed sampling points corresponded to the normative requirements for Mg2+ content.
