The present study assesses the physicochemical and bacteriological quality of
the drinking water used by the population of Sô-Ava based on the Beninese
standards and those established by the World Health Organization (WHO).
In rural and peri-urban areas of Benin where public water supply systems are
inadequate or almost non-existent, the population consumes water of various
sources of unknown qualities. A total of 67 water samples were analyzed during the rainy season (July 2017) and in the dry season (January 2018) for certain physical, chemical and bacteriological parameters using the standard
methods. The results of the analyses reveal that the physicochemical characteristics of the water used for consumption in Sô-Ava comply with the drinking water standards of the World Health Organization and those in force in
Benin except for the percentages of the following parameters: pH (41.80%);
turbidity (25.37%); the color (16.42); ammonium (17.91%); iron (40.30%);
Nitrites (4.48%); Residual chlorine (91.05). Bacteriologically, the analyses
showed a high total aerobic mesophilic flora contamination, faecal coliforms,
E. coli, faecal enterococci respectively in 89.55%, 82.09%, 50.75% and 70.15%
of the analyzed water samples. The ratio of faecal coliforms to faecal enterococci indicated that the origin of faecal contamination was human in 59.7% of
the samples and animal in 40.3% of the samples. The adoption of hygiene
measures at the water point, during the transport and storage of water, including the treatment by chlorination of drinking water at the family level was
recommended for the population concerned and household awareness on the adoption of basic hygiene and sanitation measures have been recommended
for hygiene and sanitation services. |
