Abstract: | The Faminin area in the semi-arid Hamadan state, western Iran is facing a serious deficiency in groundwater resources due
to an increasing demand associated with rapid population growth and agricultural development. The chemical composition of
78 well samples throughout the Faminin area was determined with the aim of evaluating the concentration of the background
ions and identifying the major hydrogeochemical processes that control the groundwater chemistry. The similarity between rock
and groundwater chemistries in the recharge area indicates a significant rock-water interaction. The hydrochemical types Na–HCO3 and Na–SO4 are the predominate forms in the groundwater, followed by water types Ca–HCO3 and Na–Cl. The high values of electrical conductivity and high concentrations of Na+, Cl−, SO42− and NO3− in the groundwater appeared to be caused by the dissolution of mineral phases and would appeared to be caused by anthropogenic
activities, such as intense agricultural practices (application of fertilizers, irrigation practice), urban and industrial
waste discharge, among others. |
