Abstract
The research aimed to evaluate piped water that supply the general company for pharmaceutical industry of Samarra and its suitable for drinking through the comparison with Iraqi and international standard for drinking. The study started from May (2015) until January (2016). Moreover, know the physical, chemical and bacterial properties piped water. The results showed that the piped water was matching of the drinking water by WHO and Iraqi standard. Only calcium quantity was higher than determination. The values rate for: Air and water temperature (29.44, 21.33) C° respectively, EC (431.11) μs/cm. TDS (430) mg/L, the pH (7.7). DO (4.75) mg/L, while the BOD5 (1.25) mg/L, while Alkalinity hardness (157.77) mg/L, total hardness (155.55) mg/L, calcium and magnesium hardness (78.66, 72) mg/L Respectively. While chloride (68.22) mg/L, as for the phytonutrient, Nitrate concentration were (1.902) Mg/L, the phosphate concentration values rate (0.050) Mg/L, and silica concentration (1.981) Mg/L. The heavy metals, Cu (0.028) ppm, Iron (0.121) ppm, Zinc (0.203) ppm, Lead (Nil) ppm. And it was free from bacterial growth. Thus, quality of piped water, (completely purity).
