Groundwater
vulnerability maps were created for the Corridor wellfield (~300 km2)
in the eastern Jordan using the DRASTIC and modified DRASTIC groundwater
vulnerability assessment models. The study area is considered as one of the most important well fields
therein providing partially three governorates with the needed drinking water.
Detailed geological and hydrogeological parameters as well as the land-use map
of the area were obtained from various sources to utilize both models. ArcGIS
software was used for calculations and maps preparation. As a result, the
generic DRASTIC vulnerability index ranges between 109 and 168. Thus, two vulnerability
classes were observed, moderate (9.9%) and high (90.1%) vulnerability classes.
On the other hand, the modified DRASTIC model (risk map) is taking into account
the land-use map classes in the study area. The output risk map reveals two
main classes, the moderate and high-risk areas. The moderate-risk areas occupy
9.3% of the total volume of the study area while the high-risk areas are 90.7%.
Due to the high depth to groundwater within the area (between 90 m and 390 m),
the depth to groundwater intervals was modified in the model to become more
comfortable with the situation in Jordan. The high percentage of the high
vulnerable areas against pollutants reflects the need to do more investigation for the studied
area.
