Hydrogeochemical, Geotechnical and Soil Geochemistry Characteristics of Aksaray University Campus Area, Aksaray

This study aims to investigate hydrogeological, geochemical and geotechnical properties of the Aksaray University campus area. Within this context, the hydrogeochemical results of water samples collected from 4 different water points from the campus area, geochemical analysis of 17 soil samples, and geotechnical properties of rock samples obtained from drill core and description of core-logging performed in 2008 were evaluated. Hydrogeological studies have shown that two different water facies with Na-Cl and Ca-Cl water types developed in the study area. These waters are classified as low quality, but usable, and 3 quality for irrigation water according to irrigation water standards and electrical conductivity values. According to geotechnical experiments, it was determined that the argillaceous limestone, which spread widely under the cover of the campus area, had bearing capacity of 36.5 kg/cm and belonged to the low strength rock class. As and Pb contents of the soil samples are at higher values, compared to the average upper crust values. According to the anomaly distribution maps prepared for Cl and Na elements, it was determined that east, southwest and northwest parts of the campus area contain higher values of Na and Cl than that of other parts of campus. The results of this study will provide more planned and efficient green-area studies to be carried out in the campus area and protection of the green-areas.
