ارزیابی کیفیت فیزیکی و شیمیایی منابع آب حوزه آبخیز حومه خرم‌آباد

Water quality is one of the fundamental and important issues in hydrological sciences, which is studied in two main categories: surface and groundwater quality. Due to the direct relationship that water quality has with drinking, industrial and agricultural uses, water quality is of interest to many researchers. In this study, the quality of surface and groundwater resources in the Khorramabad suburb was investigated. The measurement of surface water quality from two stations (Cham-Anjir and Bahramjo) showed that in parameters of carbonate, sulfate, calcium, magnesium and T.O.C - PH - EC and SAR, the waters of the region are classified as good to moderate quality. The evaluation of groundwater quality in the basin showed that the electrical conductivity of the groundwater wass in an appropriate range and indicating that the groundwater in this area was of good to acceptable quality for drinking purposes. The quality of water varies from C2S1 to C3S1 in terms of agriculture, and it is in a suitable quality and among the parameters, the concentration of soluble nitrate in the southwestern areas of Khorramabad was higher than the standard limit. Finally, it was suggested to prevent any possible pollution from entering the city by careful and continuous monitoring of the sources, reservoirs and distribution network of the city.
