Water Quality of Kufa River and Effect Pollutants on It

The present study was conducted to indicate the possible environmental effects on Kufa river in four selected sites along this area during November 2011 to April 2012. the physical and chemical water properties were investigated in this study .The results showed clear coordination between air and water temperature in all study locations. Air and water temperature ranged between (11-23.5) Cº and (10.5-22) Cº respectively. pH, Electrical Conductivity EC, Total Dissolved Sold TDS, Total Suspended Sold TSS, Salinity ranged between (7.9-8.8), (1099.7-1597.7) μs/cm, (459.3-718.7) mg/L, (1.1-9.6) mg/L(0.3-0.6)ppt respectively. Turbidity, Dissolved oxygen and BOD5 value ranged between (0.7-5.7 )NTU (6.57-12.83) mg/L (0.4-4.2) mg/L. The study showed that the water of the river was high alkaline (124-289) mg CaCO3/L and bicarbonate ions were dominant throughout the study period. The total hardness ranged between (315-524.4) mg CaCO3/L, which was classified as very hard water, while the concentrations of calcium and magnesium were (113.3-412.3), (8.4-83.1) mg CaCO3/L respectively. The nutrients showed clear fluctuation in their concentrations. Nitrite values were (0.003-0.192) mg/L and nitrate values were (0.5-1.3) mg/L, while reactive phosphate was (0.001.-0.04) mg/L. The sulfate values were (196.1-413.2) ml/L. The present study was conclusion fluctuation water levels and cant swage water in river negative impact on water quality.
