The water resources of a country are used in a variety of ways. For example, in the agriculture and industrial sectors, for public and recreation use, for aesthetic enjoyment and the propagation of wildlife, and for the treatment of waste, decisions made concerning water standards must keep in mind all these areas, this is not always a simple task, especially when certain interests’ affect and conflict with one another. When conflicts occur, water standards must be established according to the best interests of the people.

These interests require the preservation and restoration of water characterization for the greatest numbers of use. Water is selected for various uses, according to certain characterization standards which it must meet in order to be deemed suitable for the purpose intended. These standards are very important, and should be established only after careful consideration by knowledgeable groups.

The government department responsible for waters of drainage basins is wise to consult with agencies or persons who have expertise and are interested in present and future water use. There are many variations in the characterization of water that is suitable for irrigation uses. For example in humid areas heavy rainfall before and after the growing season leaches excess salt and other element from the soil. This allow water to be used for irrigation which otherwise would be considered too poor in characterization for most crops.

            Nearly all water contain dissolved and trace elements, many of which result form the natural weathering of the earth’s surface. In addition drainage waters from irrigated lands and effluent from city sewage and industrial waste water can impact upon water characterization these and suspended materials influence the soil structure. The classification of water source is usually based on chemical analysis of water. Irrigation water is usually classified in a way different from that used for industrial and sanitary purposes. Some of the criteria of classification include concentration of soluble salts, salinity hazard, concentration of sodium relative to calcium and magnesium (Sodium hazard) and concentration of boron, chloride and other constituent that may be harmful to crops.

            In order to predict the success of irrigation in any particular situation it is essential to have adequate information on the characterization of irrigation water, its effect on the physical and chemical properties of the soil, water transmission characteristic of the soil, salt build up in the soil and the climate of the area, irrigation water characterization is determined by it’s potential to cause problem which will reduce yield unless special management practices are adopted to maintain or restore maximum production capability under given conditions.

            Due to irregular distribution of rainfall in the study area, irrigation is a sure means of increasing crop production. Based on this, therefore, there is the need to document the water source for irrigation of this state.
The general objective of the study is to find out if the water different source of Ekoli Edda is good for irrigation.

The specific objective of the study were;
1.         To determine the chemical properties of water for irrigation.
2.         To evaluate physical properties of water for its suitability for irrigation.
