WATER QUALITY AND HYDROGEOCHEMICAL CHARACTERISTICS OF SURFACE WATER AND GROUNDWATERS IN AKSU (ISPARTA) PLAIN

In this study, geological, hydrological, hydrogeological, hydrogeochemical characteristics of the aksu (isparta) plain were investigated. in addition, determination of the water quality and availability in current status besides groundwater dynamics were aimed in the scope of work. the study area is located in the southwest turkey, and lithological units belonging to beydaglari autochthonous and antalya nappes are observed. the most important surface water and groundwater reservoirs are aksu river and alluvial-karst aquifers, respectively. hydrogeochemical characteristics and quality of the water are important because water is used as drinking water and irrigation water in the plain. for this purpose, in situ measurements and chemical analyzes were carried out in the period of may-2013 on water resources. according to the obtained results, water resources is mg-hco3, ca-hco3, and mg-ca-hco3 facies. according to the water pollution control regulation, all surface and groundwaters are determined in 4th water quality class in terms of sulfur owing to water-rock interaction. the assessment of the usage properties of the waters indicate that water sources is suitable for drinking and irrigation water usage in generally.
