Appraisal the Quality of Drinking Tap Water in Different Regions of Kirkuk city
Keywords:Heavy metals, drinking tap water, water quality
This study was conducted to demonstrate the suitability of drinking tap water from different regions of
Kirkuk city byanalyzing some chemical and physical properties included (temperature, pH, turbidity, electric
conductivity, total soluble solids, total hardness, total suspended solids, nitrates, calcium, magnesium,
chloride, sulfate, sodium and phosphate) and eight heavy metals concentration including (Cd, Cr, Cu,
Fe, Zn, Ni, Mn and Mg) which have been detected in drinking water. The drinking tap water of Kirkuk
city processed by the Directorate of Kirkuk’s water for human consumption, all data compared with (IQS
417/2001) except for temperature. The results offered that the concentrations of 8 studied metals are little
than National Standards Organization of Iraq (IQS) except for (Ni) which is found to be high (12.267mg/L)
dose which not meet specifications, the results were analyzed using the analytic Jena AAS NOVAA 350.
The results of chemical and physical properties compared with drinking water standards displays that the
concentration of studied chemical and physical are little than the estimated levels that were announced by
the National Standards Organization of Iraq(IQS) except for two analysis(turbidity and total soluble solids)
were found to be highest rate(6.9NTU) and (79mg/L) respectively which does not meet specifications.
