| ABSTRACT: | The catchment area of Wadi Rabba is situated on outcrops of the Western Mountain (Yarkon- Taninim) aquifer which is a major source of drinking water. A study was carried out to investigate the influence of anthropogenic pollutants, mainly industrial effluents and urban sewage in the Wadi Rabba catchment area, upon the quality of the underlying groundwater. The study included chemical and bacteriological analyses of the effluents and of the water in surrounding wells. Isotopic analyses of uranium, tritium and radiocarbon content in some of the wells were also made to study the age of the groundwater. These analyses together with stratigraphic cross sections were used to identify the sources of the groundwater. The study revealed local effects of pollution sources on adjacent wells. However, no evidence was found for the effect of pollutant sources over aquiferous outcrops on wells lying downstream. This was ascribed to differences between the stratigraphic unit and hydraulic characteristics of the outcrop and that of the wells, as well as to the effects of chemical precipitation and dilution.
