Abed a*,}, journal={Engineering and Technology Journal مجلة الهندسة والتكنولوجيا}, volume={39}, number={3 part (A) Engineering}, pages={512-519}, year={2021}, abstract={The Tigris River is considered as one of the two major rivers in Iraq. Manyfactories are located on both bank of the river such as the public companyfor soft drinks, Al-Dura oil refinery, chemical, plastic, and leather factories,Dura electricity station, and others. It is well known that most dischargeeffluents into the river do not match national standard specifications. Inaddition, the major aim of the presented work is to assess the Water QualityIndex (WQI) for the Tigris River starting from The University of Baghdad to0.5 km downflow the confluence of the Diyala River. The samples werecollected during a six months period; one sample each month for fifteenlocations along the Tigris River. Different parameters were studied tocalculate the water quality index: Total Dissolved Solids (TDS), NO3, HeavyMetals (Cadmium, Chromium, Lead, Zinc), and pH. The water quality indexwith regard to such samples is ranging between (58.24 and 160.66) andclassified between poor to unfit.
