Geo-structural analysis accompanied with GIS vulnerability mapping, validated by hydro-chemical modeling, in determining spatial expansion of landfills, case study from Jordan
Dumpsites have to be carefully sited, since they can harm groundwater quality, especially in countries like
Jordan, that depends totally on groundwater resources. The northern part of Jordan witnesses an accelerating
population growth because of refugees? growth, according to the political situation in the region. Dumpsites
have to be accordingly expanded. This study investigates two dumpsites in two areas in order to determine
safe expansion directions, utilizing DRASTIC index for groundwater vulnerability against pollution and using
GIS environment. Geo-structural analysis supported the results with more reality, while hydro- chemical
analysis and water flow directions of groundwater enabled validating the results.
