Evaluation of Groundwater Quality Using Groundwater Quality Index (GWQI) in Sharjah, UAE

The rapid growth in the world population resulted an increase of freshwater needs many sectors. Groundwater is most important source specially for arid and semi-arid regions due to lack surface water sources low precipitation rates those regions. In this study, monthly groundwater quality data were collected from eleven well fields Sharjah over period 2004-2017. Water parameters including bicarbonate, calcium, chloride, fluoride, magnesium, sodium sulphate selected analysis. index (WQI) process used develop (GWQI) using above mentioned parameters. Mann-Kendall Spearman’s Rho tests adopted as non-parametric trend temporal (trend) analysis GWQI, whereas inverse distance weighting interpolation was GWQI spatial Temporal results showed significant trends 8 out 11 fields. Spatial highest values salinity ions closest northern region, lowest detected southern region.
