Conclusions
Modeling the geochemistry of GW in GIS environment using Fuzzy Logic Model provides useful information on hydrochemistry and quality of GW
The presence of radioactive tritium in GW indicates that the residence time is short and certain locations receive recharge annually and directly from precipitation.
High concentration of TDS & NO3 are observed in GW and attributed mainly to anthropogenic sources (Ain Ghazal WTP, Septic Tanks, Ruseifa Landfill)
GW with high 3H & NO3 are more vulnerable to contamination from the surface
GIS maps provide significant environmental information that could be used to manage the GW resources & used as a key factor in the public awareness to promote the value of water resources
