Spatial investigation of Ground water in Al-Bassiya Area (District) and Deternination for use agriculture

Abstract

The research aims to study The Spatial Variation of Ground Water in al-bsia district , slman township in al-muthana governorate and their validity for agrarian irrigation . the research contains the study of characteristics Quality and chemical of ground water in the study area . it's (hydrogen Electrical wiring Calcium ion , Sodium ions , Potassium ions, Potassium ions, Nitrates Magnesium ions . the result of Analyses for quality characteristics showed that the average of (ph) reached (7.5) . differences--values of turbidity in the wells of the study area reached between (73-323) and unit (NTu) at a rate of (207.3) a unit. The value of the electrical wiring Ec ranged between (280-6216) micromose / cm and at a rate of (916.4), while values ranged (PH) between (02/08 to 04/06), and when compared to those values of the parameters and standards permitted, we find that all of the sites did not exceed the reason for this is the lack of contribution of industrial activity in the study area. The chemical properties of the groundwater showed a variation in the values from one place to another. the average of sulfate ions(34.9) (so4) . either the average of nitrate ions reached (no3) (5.3) whille the average rate of becarbonate reached (.2) and the average of chloride ion (cl) reached (16) The evaluation of ground water for agricultural purposes proves that (2.81%)of the water of the wells selected falls under the classification (excellent) while (17.4%) falls under the classification of ( permissible) which means that it is permitted to use such water for irrigation. And ( 60.8%) of them falls under the classification (good) which means that such water is good for irrigation.
