The goal of the present study was quality evaluation of the natural waters in Stara Zagora Region according to two parameters: total iron and zinc. With regard to the investigations conducted during October-December, 2009: the surface waters of Stara Zagora Region, towards the measured zinc and iron concentrations, could be classified as I category; the groundwaters of Stara Zagora Region, towards the measured iron concentrations, could be classified as waters with increased content of total iron, but below the ecological threshold; the groundwaters of Stara Zagora Region, towards the measured zinc concentrations, could be classified as waters with zinc content below the ecological threshold in Gurkovo Municipality and Gita Village - Chirpan Municipality; above the ecological threshold in Novo Selo Village - Stara Zagora Municipality and Tekirska River - Chirpan Municipality; above the pollution threshold in Bratya Kunchevi Village - Stara Zagora Municipality.
