The aim of the study is to investigate the hydrogeochemical processes that control the chemistry of groundwater in the İnegöl Basin (Bursa), and to assess for its availability of groundwater for different purposes. Alluvium is the most important aquifer in the basin. In addition, groundwater can be supplied from conglomerate and sandstone levels of the İnegöl formation which is located in the base of alluvium. Kocasu stream which is supplied surface water discharge of the basin is also controlled groundwater discharge of the basin. Insitu measurements and chemical analyses of groundwater were made in two period point of view determination of quality and chemical structure of groundwater. Groundwater is Ca-Mg-HCO facies in wet season and Mg-Ca-HCO3 facies in dry season due to increases of Mg2+ ion. The increase of Mg2+ is related to solubility of dolomite and decomposition of magnesium minerals. Mn and Fe concentrations of groundwaters are exceed to drinking water standards in specific locations. These increases are based on water rock interaction with İnegöl and Nilüfer formations and anthropogenic factors. USSL and Wilcox diagrams, sodium adsorption ratio, percentage of sodium, residual sodium carbonate, and permeability index were used to determine of availability as irrigation water. Groundwater of the İnegöl Basin is suitable for irrigation water
