Potability of well water in Kirkuk city Iraq
Main Article Content
Abstract
The Kirkuk residents had resorted underground water as an alternative to the surface water the present study aims to indicate the quality of these water and demonstrates extent of their suitability drinking. For this purpose, 10 randomly distributed wells were measured, the average values 10 well were as follows:
Water temperature (22.8-25.7 Co), EC (2694.2-1384.3 sem/cm),PH(7.47-7.19) and concentration of cation’s: Na (76.8-39.8 mg/L), K (10.82-22.7 mg/L), Zinc (1.15-1.71 mg/L), cadmium (3.48-6.68 mg/L) and Calcium (270.5-165.3 mg/L).
These characters are ties were compared with the allowed limits presented by concerned authorities the results of the study indicated the absence of any results ship between temperature and depth of the wells.
Also water’s of all studied wells were not suitable of drinking as the EC, K, and cadmium were higher than allowed limits.
In addition, Na and Ca concentrations of some wells exceeded the allowed limits
