Abstract

The water quality of many karst formations in southern Zagros macrotectonical unit is related to natural geological and hydrogeological conditions and ground water mismanagement. Evaporatic sediments inciuding: gypsum, anhydrite, salt, marl, and marly limestone are existed in some formations such as: Kazhdomi, Pabdeh-Gurpi, Gachsaran, Mishan and Agha Jari formations. This situation makes the covering layers of the karst formations changing the water quality by rainfall and runoff infiltration The most important factors that strikingly differ the water quality are the distribution of innumerable salt domes (180 diapirs between 6-200 km~2) and the out gassing of oil reservoir and geothermal effects in the karst cerranes of southern Zagros range.
