Abstract:

In this study, the physicochemical, major ion, heavy metal, and pollution parameters of the Yazır Lake basin water resources and the seasonal variation of the water quality were investigated. Yeşilbarak nappe, Lycian nappes, paraallokton and neootokton rock units are located from top to bottom in the region. Groundwater supplied from alluvium and limestone units. Thirty water samples were collected from the area in dry and wet seasons. Ca-Mg-HCO3 and Ca-HCO3 were the dominant water types. The composition of the groundwater varies depending on such factors as the time of contact with the rocks, the amount of water, the temperature, and the pressures of the environment in the region. It has also been determined that another important factor affecting the hydrochemical and quality of water resources is anthropogenic pollution associated with agricultural activities. In this study, the results of the arid and rainy period analysis were evaluated statistically and the relationship of the parameters with each other was revealed. S4 and S6 samples from the waters in the study area are not potable according to WHO (2011), TSE266 (2005) standards, and Schoeller diagram. Similarly, when the waters in the study area are evaluated as irrigation water, according to the US Salinity Laboratory and Wilcox diagram classifications, the use of samples S4 and S6 is limited in both periods.
