A study Some Physico-Chemical And Bacterial Properties of Wastewater for Ramadi Teaching Hospital and its Impact on the Euphrates River

Abstract

Physiochemical and bacteriological characteristics of Euphrates river water were examined monthly to assess
the possible impacts of wastewater discharged from Ramadi Teaching hospital for the period from August
2019 to January 2020. The obtained results showed that air and water temperature mean values varied from
12.0 ±11.3 to 40.0 ± 11.3 C ° and from9.1.0 ±3.12 to 33 ±9.5 C° respectively. Also, turbidity values were
found to range from 14.0±8 to 144 ±9.6 NTU. while EC value was situated between 567.0±44.67 ?S/cm
and2899 .0±274 .3?S/cm. The current results have shown that total hardness mean values were very high
and ranged between 252.0±27.5 and1114.0±96.3 mg/l while chlorides mean values ranging from92.0±62
to 588 ±104 mg/l, but nitrate mean values were found with the range of 1.2 ±1.86 and 50 ±4.5mg/l.The
BOD mean values were found to range from1.0 ±1.2 to 34 ±6.5 mg/l, while DO mean values varying from
1.7 ±3 to 11.1 ±1.3 . This study has shown that the total bacterial count (222 to 1800000 cells/1 ml), Total
Coliform (61 -170000 cells/100 ml), Fecal Coliform (0-58000 cell/100 ml), and Fecal Streptococci (18
-9200 cells/100 ml).
