Assessment of groundwater quality using CCME water quality index in Caracosh distract, northeastern of Mosul city, Iraq.

The aim of this study is to determine the Caracosh (Al-Hamdannia district) groundwater water quality index (CCME WQI). This was calculated by taking groundwater samples and putting them into a thorough physicochemical examination. For calculating the WQI, the following 9 parameters have been considered: pH, TDS, T. Alkalinity, T. hardness, Ca, Mg, Chloride, Sulphate and Nitrate. The WQI for these samples ranges from 25.19 to 93.58. The low values of WQI has been found to be mainly from the higher values of TDS, Total hardness, T. Alkalinity and Sulphate in the groundwater. The analysis reveals that % 40 of groundwater samples of the area needs degree of treatment before consumption, and it also needs to be protected from the perils of contamination.
