N2 - Metal concentrations were determined for groundwater suspended matter from a site in the coastal aquifer of Israel which has been irrigated with secondary sewage effluents since the 1960's. Suspended matter was collected from the aquifer saturated zone by pumping and by a multi-layer sampler. Fine sediments were collected from both the unsaturated and saturated zones of the contaminated aquifer, as well as from an adjacent uncontaminated environment. Ag, Cu, Fe, Mn and Zn were leached from the samples in three sequential chemical extractions which are taken to represent the carbonate, organic and oxide phases. Comparison of the aquifer samples to those of the adjacent environment showed that Fe and Mn are primarily enriched in non-mobile fine sediments and not in suspended matter, whereas the concentrations of Zu, Cu and Ag show up to an order of magnitude enrichment in the mobile suspended matter in groundwater. The enrichment of these metals in the suspended matter indicates that metals from sewage effluents and agricultural activities have reached the groundwater.
