ASSESSMENT OF GROUNDWATER QUALITY AND ITS SUITABILITY FOR AGRICULTURAL PURPOSES IN THE LAKE SEYFE BASIN, TURKEY

Summary/Abstract: The aim of the study is to evaluate of groundwater quality and its suitability for agricultural purposes in the Lake Seyfe Basin, Turkey. For this, 20 different groundwater points were determined in the lake Seyfe Basin and water samples were taken from these points. The following 18 parameters were taken considered for evaluation: pH, electrical conductivity, temperature, sodium, potassium, calcium, magnesium, chloride, nitrite, nitrate, bicarbonate, ammonia, sulphate, dissolved oxygen, total hardness, total dissolved salts, percent of sodium and sodium adsorption ratio. Discriminant analysis was used to determine how the water quality parameters formed groups differ. As a results of the discriminant analysis were compared with guidelines based on various preceding guidelines developed and used in irrigated agriculture. In the study, the values of EC, Na, HCO3, NO3, NO2, TDS parameters were higher than the range of recommended guidelines for irrigation water quality. The main reasons of these are intensive agricultural factors such as fertilizer, irrigation water, drainage water, and livestock waste, salinity, evaporation and atmospheric pressure. Further study of these parameters to examine is recommended.
