English Abstract
The chemical analysis of 48 wells in Erbil plain, Kurdistan region , Iraq were done from July, 2013 to June 2014, in order to classify them before and after correcting (ion pairs and ion pairs+activity).
The main results were summarized as follow: Depending on Scofield,s classification (1935) only water of 10 wells located within harmful class, while the water of other wells were suitable for irrigation, while depending on Richards (1954) water of (6) wells located within (C2-S1) class, water of (25) wells were have (C3-S1) class, while the water of (17) wells have (C4-S1) class.
While relying on Wilcox classification (1955) the water of all wells have probably safe class.
Considering salinity potential only water of wells (36 and 39 to 48), (33 to 48) and (18 to 48) have bad class for high, medium and low permeable soils respectively.
Depending on Ayers and Westcot classification (1994) the water of wells (39 to 48) have severe degree of restriction use for irrigation.
Depending on concentration of (Fe, Zn and Cu) the water of all wells were suitable for irrigation.
Depending on Doneen classification (1954) correcting ion pairs and activity caused changes in water classes of wells (29 to 35 and 38) from moderate to good class and changed water quality of wells (36, 39 to 44) from bad to moderate class.
Correcting ion pairs and activity caused an increase in SAR values of water, the range of SAR*/SAR and SAR**/SAR ratios were (1.11- 1.25) for water samples respectively.
The dominant ion pairs in the studied water were (CaSO4)0, (MgSO4)0.
