英文摘要	This study proposes the evaluation of GIS-based groundwater quality index (GQI) and spatial variability with a hybrid system that combines Fuzzy Logic with GIS-based GQI. A case study in the semi-arid area of Punjab, namely Rupnagar, illustrates the proposed hybrid outline. Two GIS-based GQI models GQI-10 (using ten water quality parameters (WQPs)) and GQI-6 (using six apprehensive/crucial WQPs), as well as hybrid Fuzzy Logic GIS-based GQI (FGQI) (using six crucial WQPs) models, were developed using trapezoidal membership functions and rule sets based on expert's knowledge. Performance comparison of GQI models showed that the FGQI model predicts improved groundwater quality than the GQI-10 and GQI-6. FGQI model variance, RMSE, and R-2 values are 84.25, 6.49, 0.89, respectively. Results have shown that the developed FGQI model is successful and GQI modelling suggests the use of northern and central groundwater without treatment to be unsafe for drinking purposes.
