An assessment of the impact of Mingoa Stream input to the bacteriological quality of the Municipal Lake of Yaoundé (Cameroon)
Résumé
To investigate the deteriorating bacteriological water quality of Municipal Lake of Yaoundé, the degree of pollution of the Mingoa Stream, the main tributary of the lake, was evaluated for total coliforms, thermotolerant coliforms, and fecal streptococci. Concentrations of these bacterial indicators in Mingoa Stream were higher than those allowed by international norms for the bacteriological quality of recreational water. Thus, this stream contributes to the high levels of bacteria number in the water column of the Municipal Lake.
