For many years, raw sewage effluents from the City of Nablus in Palestine have been discharged into Wadi Zeimar and Wadi Askar. Consequently the quality of water in both wadis is extremely poor and has the potential to cause significant groundwater pollution. Efficient design of wastewater treatment plants requires an evaluation of the vulnerability of the aquifers to sewage infiltration. This evaluation has been undertaken through a programme of hydrogeological investigations, supported by numerical simulations. The relevant limestone units have pronounced mature karst features above and below the water table. Piezometric data indicate that the water table in the upper-most aquifers is shallow and the magnitude and orientation of hydraulic gradients suggest that extensive pollution can be expected. Numerical simulations confirm these deductions. Hydrochemical interpretations reveal that pronounced variations in groundwater quality which can be ascribed to sewage effluents already exist. Appropriate levels of treatment for new wastewater plants have been suggested to eliminate groundwater pollution in the future.
