The Index of Ground Water Quality For Selective Area Of Dibdibba Aquifer Southern Iraq Using Gis

Abstract

This research aims to apply the Ground Water Quality Index (GWQI) to evaluate the groundwater samples in the selective area of upper part of dibdibba aquifer southern Iraq. The parameters (TDS, Ca, Mg, Na, Cl, HCO3, SO4, Cd, Pb, Ni, and B) were used to calculate the (GWQI). The analysed values of these parameters were only exceeding the limits of WHO drinking water standard. The results of compared the (GWOI) values in the study area with GWQI water classes type showed that ground water in study area was very polluted and unsuitable for drinking use. The GIS maps show the GWQI values range not only in sample location but for whole study area which useful to choose a less polluted areas for wells drilling.
