TY - JOUR ID - TI - Evaluation of Microbial Quality of The Drinking Water of Al-Bashaar Water Treatment Plant in Wasit Province Southern of Iraq AU - Ahmed J. Al-Azawi AU - Wisam B. Al-Tmemy PY - 2018 VL - 36 IS - 2 Part (C) SP - 128 EP - 136 JO - Engineering and Technology Journal مجلة الهندسة والتكنولوجيا SN - 16816900 24120758 AB - The microbial quality of drinking water which distributed form Al-Bashaarwater treatment plant and number of residential areas fed by these water treatmentplant was studied each month over six months during a period extended from theOctober 2013 to April 2014, through the purification stages up to residential sites atdifferent areas situated with various distances from the supplying source, two sampleswere taken monthly. This station derived their water from AL-Gharraf River in thesoutheastern part of Iraq, where the feed areas of the city with drinking water. Thisstudy included detection of bacteria, evidence of contamination of water and somephysical and chemical variables. Results of Bacteriological tests showed increasing inTPC, TC, FC, E.coli and FS bacteria in December and January in all study locations ascompared to those of the other months for water plant raw and drinking water and theFS values was less than other bacterial types for water plant .Physiochemical testsshowed that air temperature at sampling time was varied between17 and 34°C andbetween11.5 and 29°C, for water temperature at sampling time also. The results of pHmeans were within the allowable limit. The highest mean value of turbidity recorded forraw water was in December and the lowest value was in April, while the highest meanvalue recorded for drinking water was again in December and the lowest value was inApril. The highest mean value of residual chlorine was recorded in March; the lowestvalue was 0 mg/L in some of the farthest points of the plant. From this study, it can beconcluded that the drinking water produced by Al-Bashaar plant is mostly undesirablefor drinking according to the Iraqi and WHO standards for the drinking water.
