4 Conclusion
This study assessed the physicochemical properties of drinking water from ten different locations in Missan
province during the months of October, November and December, 2015. The analysis was carried out by taking
certain important parameters like pH, TUR, EC,Ca
+2
, Mg
+2
, TH, Cl

, SO
4 -2
TSS, TDS, NO

and PO

. The results
showed that some of the parameters determined did not exceed the permissible limit of the world Health
Organization WHO and Iraqi standards for drinking water such as pH, calcium ion magnesium ion, total
suspended solid, nitrates and phosphates, whereas electrical conductivity, turbidity, total hardness, total dissolved
solid, chloride ion and
sulphate
ion were above the permissible limits of WHO and Iraqi standards. The
physicochemical properties in the study suggested that the samples water is not suitable for drinking purpose.
