Assessment of water quality for drinking and irrigation purposes: a case study of Baskoy springs (Aglasun/Burdur/Turkey)

It is important to know the quality of water resources for drinking, domestic and irrigation in the rural area. Because, in recent times, there has been increased demand for water due to population growth and intense agricultural activities, so, hydrogeochemical investigations come into prominence for the groundwater use. The purpose of this paper is to evaluate water quality of Baskoy springs for both drinking and irrigation purposes. The geochemical processes and quality of springs were followed as seasonal in the study area. In view of geochemical classification, springs are Ca-Mg-HCO3 water type for both seasons. Comparison of geochemical data shows that majority of the spring samples are suitable for drinking water. On the other hand, chemical indexes of springs with various classifications were calculated for irrigation purposes. According to the classifications (electrical conductivity, total dissolved solids, total hardness, salinity hazard, percent sodium, sodium adsorption ratio, residual sodium carbonate, residual sodium bicarbonate, permeability index, potential salinity, soluble sodium percentage, magnesium ratio, and Kelly's ratio), Baskoy springs are suitable for irrigation purposes. However, water quality of Caygozu spring is different the other springs due to the high electrical conductivity and total dissolved solids. Also, groundwater mineralization processes and rock-water interaction are controlled with bivariate diagrams of major elements.
