Abstract

Groundwater resources polluted by different compounds limits the possibility of using this important resource. In this research, with the intention of improving the controls for water quality, geo electric methods and determination of the relation between the chemo-physical properties in groundwater and the aquifer and impervious layer of electrical resistances were investigated. The wells in the Yaftabad area in Tehran were investigated in this research. The results show that the true resistance of the aquifer is about 90–134 ohm.m, and for the impervious layer it is 19–78 ohm.m. According to the aquifer and impervious layer resistance and the results of laboratory study diagrams, equations and correlations between the chemo-physical properties of groundwater and true specific electrical resistance were obtained. There is a relation between the true specific electrical resistance of the aquifer and the impervious layer with the most numerous of chemo-physical properties. The extent of the correlation constant variation for NO2, NO3, NH3, and pH is medium and for SO4 is strong with true specific electrical resistance of the aquifer. The extent of the correlation constant variation for NO2 is medium, for NH3 and SO4 is strong and for NO3 and pH is too strong with true specific electrical resistance of the impervious layer. The average extent value of the correlation constant variation between chemo-physical properties in groundwater and the true specific electrical resistance of the aquifer is equal to 0.698 and for the impervious layer is equal to 0.539. Keywords: groundwater quality, aquifer, impervious layer, geo electrics.
