Saod WM, Rashid FA, Turki AM, Mansoor Al-Taee MJ., Water quality indices for Euphrates River, Onl J Vet Res., 23 (5):407-413, 2019. Authors describe bacteria, physical and chemical properties, conductance, suspended and dissolved solids, pH, hardness, trace and heavy metals for water quality index (WQI) from 5 samples of different locations of the Euphrates River, Ramadi, Iraq, Spring 2018. We found aerobic bacteria reached 114*10-8 cell/ml with Enterobacter amnigenu, Klebsiella aerogenes, Pseudomonas spp, Escherichia coli, Proteus sp, Shigella spp and Streptococcus faecalis predominating. Water pH varied 7.6-7.8 with 7422mg/L dissolved solids and hardness of 1333.238 mg\L exceeding limits of 500 and 1000 mg\L. Sodium levels were 145.1 0.94 and potassium 11.08 1.06mg/L (within limit). Calcium (1057 mg/L), magnesium (56.46.4 mg\L) and sulphate (265.61.47 mg/L) exceeded permitted levels whereas and nitrate ions were below limit (2.2 0.8mg/L). Conductance was 1245.291 s\cm exceeding limit of 750 s\cm and total suspended solids 21537.5 mg\L, well above limit of 50 mg\L. There were no significant correlations between water quality and conductivity, hardness, calcium but there was with coliform count (P 0.001) and magnesium levels (P < 0.05). We find that water samples from The Euphrates River, Ramadi, Iraq, were of poor to very poor quality, and should not be ingested by animals or humans
