Hydrochemical Evaluation of Erbil City Aquifer / North of Iraq

Abstract

Eribl city lies in the north part of Iraq within the middle basin of Eribl plain(1400) km2, while the city of Eribl is only (70) km2. The research deals with thestudy of hydrochemical features of ground water. (20) wells were sampled toidentify the quality and origin of the water for municipal use. The results showedthat the water is clear with no impurities, the temp. was (20.31)cº, the water wasslightly basic with PH.(8.07), E.C.(353.65) μ mhos/cm, TDS was (244.45) ppm,and the total hardness (79.66) ppm. The type of the water was classified as fresh water, according to (Schoeller) classification with domination of the bicarbonategroups. According to (sulin) classification, the type of water was of (Na2So4) andof atmospheric origin, the study concluded that the water was suitable for all kindof human uses
