Evaluation of Physico-Chemical and Microbiological Qualities of Drinking Water of Benin Republic South Aquatic Cities

Abstract

This study focuses on Sô-Ava’s population well-being regarding to drinking water quality especially in the villages of Ahomey- lokpo and Ahomey-ounmey. Samples of water were taken at three kinds of sites (bollard fountains, river Sô and shallows) and analysed for searching their physico-chemical and microbiogical characteristics. The differents parameters values obtained are sometimes higher than standards. Indeed for example the averages are ranged from 0.0264mg/L to 0.5247 mg/L for nitrites and from 0.73mg/L to 2.86 mg/L for total iron. Averages microbiological parameters also range in 0-19600 UFC/100mL for faecal coliforms and 42-560 UFC/100mL for total coliforms and finally 0-190 UFC/100mL for faecal streptococcus.
