Abstract
The present study was conducted on Tigris river at Salah-Aldin province included selected five site distributed at the distance of the river, which are studied 17.4 km from November 2012 to June 2013. The first site located close to station for refinery drinking water at Aldour city, the last site was at Abo-Dalf area.The results showed that air temperature ranged 5-39 C°, while water temperature ranged 8-24C°, and turbidity ranged 3.55 - 192.5 NTU and the values of electrical conductivity between 356-620 µS/cm, and observed dissolved oxygen values ranged 4.5-9.6 mg / l and based on BOD5 values the water was clean, its ranged 1.4-15.2 mg / l. While pH values were low, with levels ranging between 6.7-8.2. Total Hardness was affected by the geological characteristics of the soil in which the water is located in the stations, and the water was very hard, which was mostly due to the ion of the bicarbonate, total hardness values ranged 94-284 mg /l, Alkalinity values recorded 56-1108 mg / l while chloride ions were within the permissible limits ranging between 21.3-158.575 mg / l, while the sulfates values ranged 22.2-466.2 mg/l, while the phosphate values ranged 0.417-7.519 µg / l, followed by silica was recorded between 0.463-13.901 mg / l.
