Abstract
The physico-chemical characteristics of the AL-Husseiniya River's water in four sites along the river through 12 months starting from January 2007 to December 2007,and it was found that the water was (Olighahalin) extended between (400 – 1100) µs/ cm. Disssolved oxygen extended between (5-12) mg/l. The pH levels extended between ( 7.7 -8.6). The water was alkaline extended between (107– 380) mg/l, with dominant bicarbonate ions in all study period. The water of the river was account as very hard water. The total hardness was extended between (300 – 580)mg CaCO3/ l). Among the cations and anions measured in the study, Ca+2 was higher than Mg+2 and SO4-2 was clearly higher than Cl-1. Nitrate was the dominant inorganic nitrogen sources. The concentrations of NO3 , NO2 , PO4 was extended between (100-530) and (0.2-31) and (9-70) μg/l respectively. Seasonally Concentrations of four Heavy elements. (pb, Cr, Hg, Cd) determined in the study and extended (10.9-35.4) and (56.7-73.5) and (74.8-114.4) μg/l respectively. It was excess the limited Iraqi and international water Guidelines
