In the Kurdistan region-Iraq there are a number of natural springs. These springs are located in different geographical areas and each of them may differ from others in odder and mineral contents. HammamJalli is one of these springs which is located near the city of Koya in the Kurdistan region and is attracting thousands of local people every year, mainly, those who are suffering from skin diseases. So far, the thermal behavior of hammam Jalli's spring and its therapeutic effects are not fully understood and according to the authors' knowledge there is no scientific research work in such detail prior to this study. This being the case, the thermal behavior of hammam Jalli's spring was studied systematically. The temperature measurement results shown a large temperature difference between the Hammam Jalli's water and the temperature of the surrounding air, which can lead to a conclusion that hammam-Jalli can be introduced as a thermal spring. In addition to the water conductivity and pH measurements, during this study, the hammam Jalli's water was analyzed chemically to understand its therapeutic effects.
