An Assessment of the Impact of Mingoa Stream Input to the Bacteriological Quality of the Municipal Lake of Yaoundé (Cameroon)

To investigate the deteriorating bacteriological water qualityof Municipal Lake of Yaoundé, the degree of pollution of theMingoa Stream, the main tributary of the lake, was evaluated fortotal coliforms, thermotolerant coliforms, and fecal streptococci. Concentrations of these bacterial indicators inMingoa 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. Copyright Kluwer Academic Publishers 2001
