An Analytical Comparative Study of Refined and Raw Water of Kerbala Government

Abstract

An analytical study on refined water projects and their recourses (i.e. Husaniuah river) at kerbala government during 2004-2005 to evaluate the efficiency of those projects and to investigate if the output data were matched with the world health organization measures and the out coming information from Iraqi ecological offices. The following projects 7 Nissan , Hi alhussain , Hi oroba , old staff , mew hurr , Shabanat , Western valley have been chosen.A weekly samples from refined water and raw water were taken throughout a year commenced on January up to December to determine some of the physiochemical and biological characteristic. Results showed that pH , cl- , Alk. , TDS measurements were at lower limits, where as, E.C. , Turb. , TH were at higher limits, with WHO standards. Ca+2 was the only element which increased at the whole stations which resulted in increased TH and EC values while Mg+2 was within reasonable limits. Statistical analysis for refined water showed the standard error for pH was at lower values, while for EC and the most others traits were at higher values. Uniformity values were lower than 85% for Turb. , Mg+2 and Alk. Which indicated that those measurements were irregular. Results showed that the measurement of raw water were slightly higher than those of refined water according to ASCE standard and they classified from excellent to good grade. The statistical analysis showed S.E values appeared wide differences between higher and lower values for the characteristics being examined, but they were acceptable in general with the most U.C. values despite the fact that they were matched with Michael, 1978 standard. The bacteriology investigations were done and the results were negative which proved the usability of water.
