Analysis of Water Quality using-Chemical –Physical- Biological Parameters of the Kinds of Water used for Drinking in the

The current study was carried out to analyze and evaluate the drink water samples collected from residential areas of Baghdad Province al-adhamiya City. The level of TDS, alkalinity, Ca, Mg, Hardness, Electrical Conductivity, pH, and selected heavy metals (Fe, Cr, Cd & Zn) were determined. The results showed that all water samples have alkaline pH. All these water samples have very low concentration of Fe and Zn. The concentration of Cr and Cd was observed higher than the prescribed limit of WHO and ISI. In the light of this analysis we can conclude that all these water samples require some treatment before their use for drinking purpose. The field study was conducted for the three sites of water in the province of Baghdad province, al- adhamiya city (river water and piped water and water tank) where the samples were collected during the month of September 2014. The result establishes that drinks water sample in three site, is useful for irrigation and household purpose, and suitable for drinking. A correlation study has been carried out amongst all possible pairs of the physical and chemical parameters to assess drink water quality. Correlation study indicates that different parameters are strongly interrelated. The correlation and regression provides an excellent tool for the prediction of parameter values within reasonable degree of accuracy. Were studied and compared with National Drinking Water Quality Standard (NDWQS) of Iraq and WHO water quality guidelines. The results revealed that most of the parameters were in normal range and indicated suitability for drinking purposes
