Hydrochemical assessment of groundwater in Zeviercheriand Kheran

Category Hydrogeology
Group GSI.IR
Location 21th symposium on geosciences
Holding Date 24 May 2008

   Abstract:
      Zeviercheri and Kheran plains are located vicinity of Molasani town and about 40km in northeast of Ahvaz City. Due to Bakhtiari conglomerate formation in the central part and its weathering products a promising aquifer has been developed in the vast part of studied area. The main source of water supply is groundwater and about 140 shallow and deep excavated wells in the area which show variation in total dissolved solids as well as concentration of ions. In order to evaluate chemical characteristics of groundwater, source of salinity and to determine trend of chemical changes in Aug 2003, 62 water-sampling stations (shallow, semi deep and deep wells) were selected and concentration of major elements (Ca, Mg, Na, K, HCO3, SO4 and Cl) were computed. In this investigation, in addition to over all quality assessment, variation in chemical trend, source of salinity, water type and mixing characteristics of groundwater are discussed.

In this investigation, in addition to over all quality assessment, variation in chemical trend, source of salinity, water type and mixing characteristics of groundwater are discussed.
