%X In this study, hydrogeology of Kayaa£¿£¿l and Karaa£¿a£¿ villages in U£¿ak province and hydrogeochemical properties of thermal and cold waters were investigated. The Paleozoic aged E£¿me formation which are formed from schists and marble bands is the main reservoir rocks of the hydrothermal system, the impermeable levels of the Tertiary and Quaternary units constitute the cover rocks and the fracture lines developed by the faulting are the flow paths carrying the fluids to the surface. Groundwater infiltrating to deep in the region heat due to the geothermal gradient. In the study area, it was determined that the thermal waters are Na-HCO3, the cold waters Ca-Mg-HCO3 and the mixed waters are Ca-Mg-SO4-HCO3 waters. The increase of Na in the thermal waters depends on the water temperature and the rock-water interaction process. Kayaa£¿£¿l thermal water is saturated with albite, analsim, aragonite, calcite, barite, calcite, cristobalite, dolomite, fluorite, gypsum, quartz and sanidine minerals. The reservoir temperatures of the thermal waters are calculated as 102-1470C according to the silica geothermometers. In addition, trace metal contents of groundwater such as Al, As, B, Fe, Cd, Cr, Mn, Ni and Pb were also researched. The increase of As in the thermal and mixture waters is directly proportional to the water temperature. The increase of As in the cold waters originated from water-rock interaction. The high Al and Mn values of water are due to the anthropogenic activities
