Evaluation of water Euphrates river at Al-Khidir city district – Al- Muthanna governorate – Iraq .

 Abstract  

This study was conducted to investigate some physical – chemical and  bacteriological proprieties for Three Stations In Al-Khidir District, First station Was before enter river city, Second Station, In city center, Third station, After the river out of city. Samples were obtained during February, 2015 To June 2015. Stations water quality were ordered as below: temperature (21.2 – 21.3 c ), turbidity (9.29 – 9.87 N.T.U ), dissolved oxygen ( 9.8 – 10.36 mg – L ), biological demand oxygen (2.5 – 3.14 mg – L ), pH   ( 7.9 – 8.0 ), electrical conductivity (4283.92 – 4351.0 µS – cm ), salinity ( 2.68 – 2.72 p.p.t ), total dissolved solids ( 2741.7 – 2784.6 mg – L ) , total Aerobic Bacteria  (101.1 – 164.1 cell * 10-3 ) , total coliform Bacteria   ( 42.4 – 69.7 cell * 10-3 ), and fecal coliform Bacteria  ( 50.7 – 77.3 cell * 10-3 ) had below the maximum allowed limits for drinking and other uses. Statistical analysis showed there are not significant differences among the means of studied proprieties of all stations of water expect Dissolved oxygen.
