WATER quality assessment of drinking water has been studied in Benha city, Qalubia Governorate, Egypt between April 2015 to March 2016 to evaluate the quality of different types of water according to physicochemical, chemical and bacteriological aspects. Twenty four samples were collected during the four seasons from different places in Benha City. Two kinds were analyzed; Benha filtered water and raw water of River Nile. The results indicated that the average values of physicochemical, heavy metals, trihalomethanes and bacteriological parameters in Benha filtered water treatment were within Egyptian standard (2007) and the World Health Organization (WHO) of water quality with comparison to raw water. The dominant bacterial isolates in the raw water samples were Escherichia coli and Enterobacter aerogenes; while the filtered water samples were 100% free from pathogenic bacteria and coliforms |
