The potential impact of industrial wastes on water resources in Amman-Zarka basin
1991
Gedeon, R. (Ministry of Water and Irrigation, Amman (Jordan). Water Authority Laboratories)
Scarcity of water supply and increasing demand for water in a densely populated area like Amman-Zarka, as well as new threats and contaminants, have emerged, leaving the area with such diverse water quality problems as eutrophication in surface waters and nitrates in ground waters. The problem has been aggravated by increasing emissions of industrial effluents from more than 60 industries located in the catchment area of Amman-Zarqa. Thus the present work has been confined to assessing industrial wastes and their impact on water resources. Water, as part of the human environment, occurs in four main forms - as groundwater, in surface water bodies, in the sea and as vapour in the atmosphere. The present work deals with the first two only, with main objectives as follows: Assessment of man - made impacts on water quality in the area. Identification of sources of pollution and pollutant pathways and behaviour. Determination of trends of chemical constituents and organic pollutants in water resources
