ABSTRACT
The use of wastewater in agriculture is of supreme importance in arid and semiarid countries. In such countries water is becoming an increasingly scarce resource, and planners are forced to consider any source of water that might be uscd economically and effectively to promote further development. At the same time, with population expanding at a high rate, the need for increasing food production is apparent. Whenever good quality water is scarce, water of marginal quality will have to be considered for use in agriculture. However, marginal quality water requires more complex management practices and more stringent monitoring procedures to avoid the possibly hazardous effects of the discharge of industrial effluents to public sewers or water in which people bathe.
