Water Quality Assessment of Some Well Water in Erbil City by Quality index, Kurdistan Region-Iraq
Keywords:Well water, WQI, Erbil, Kurdistan, Iraq
The present work is aimed at assessing the water quality index (WQI) for the six well in Erbil city. This has been determined by collecting groundwater samples and subjecting the samples to a comprehensive physicochemical analysis. For calculating the WQI, the following 8 parameters have been considered: EC, TDS, pH, Alkalinity, Hardness, NO3, Ca+2, Mg+2. The WQI for these samples ranges from 24.825 in Rizgari well No. 1 to 84.048 in Azadi well No. 8. The results indicated that water quality of wells (Azadi 8, Ankawa 9, Ronaky 1 and Badawa 13) remains Good and Tayrawa well No. 1 remains excellent in the years 2004, 2005, and 2012. But well of Rizgari No. 1 changed from good in year 2004 and to excellent in 2012.
