Restoration of the Rivers in Israel's Coastal Plain

Abstract

Israel's chronic water shortage has aggravated problems of river pollution, as almost no dilution of inadequately treated wastewater takes place. Since the early 1990s, large investments were made to build new wastewater treatment plants, designed to produce effluents of secondary quality or better. Consequently, it became of interest to examine the possibility of using tertiary treated effluents as a water source for rehabilitation of aquatic habitats. A survey of water quality in clean and polluted segments of Israel's coastal rivers was initiated, including analyses of riverbed sediments. Although many segments are still heavily polluted, there are examples of measurable improvement in water quality, which should lead to better sediment quality. It is argued that sediments serve both as a memory bank of past pollution events and as an ongoing source of anaerobic and toxic compounds, such as sulfides and ammonium compounds. Their chemical compositions are, therefore, of much importance for river restoration processes and monitoring.
