Özet:

Gölhisar (Burdur) Ovası, located in the southwest of Turkey, has a drainage area of 1505 km2. In the area of review, the Greenbarak plate, the Likya plate and the paraallokton and the neootokton rock units containing the ancient units of the Quaterner are floating. In Ovada the subterranean is taken from the alivion, conglomerate and square units. In the area, the general subterranean stream direction is seen to the south of the river. The figure of the subterranean table in Ovada is 960-1644 m; the depth of the subterranean surface is measured between 4.0-57.07 m. Hydrogeochemical assessments and quality and pollution analyses of the subterranean are conducted in the Shadow Valley. In the area of examination, the presence of subterranean Mg-Ca-HCO3, Ca-Mg-HCO3 and Ca-HCO3 hydrogeochemical water phases has been detected. The increase in Mg in the subterranean is caused by the Neogenic Chameli formation, Orhaniye formation and the interaction of rock-water with Marmaris peridoditis. The US Salt Laboratory and Wilcox Diagrams have been determined to be suitable for use as hydration water with the assessment of the parameters of increased sodium carbonate (RSC), passivity index (PI) and magnesium danger (MT). The most important contaminant element for the subterranean areas in the region are agricultural activities. This has led to an increase in nitrate content in the subterranean areas throughout the oval. In addition, heavy metal content such as Al, As, Cr, Cu, Fe, Mn and Pb of their undergrounds has been studied. Heavy metal analysis results were compared with the Turkish Drinking Water (TSE 266) and the World Health Organization (WHO) standards and the limit values were not exceeded.
