The data used in this work were collected between the month of January and February of the year 2016 in the Lukaya River, located in the commune of Mont-ngafula, in the city province of Kinshasa. The DRC does not have a specific law or a water code and a clear national policy on integrated water resources management. Several projects exist and are underway with the support of German cooperation. The framework for the application of the laws of the related sectors is hardly applied this favors pollution, the irrational exploitation of fishery resources, inappropriate use of chemicals raising hygienic and environmental concerns. The objective of this work is to assess the environmental impact of the microbiological pollution of the water in the Lukaya River. The water samples were taken from the different sites in 600 ml plastic Canadian bottles and their analysis was performed at the INRB laboratory and the approach adopted in this work is that of membrane filtration which led to the following results: a high bacteriological concentration and numerous pathogens such as Escherichia coli, Proteus vulgaris, Enterobacter, Proteus penneri, Citrabacter and many other bacteria which testify to faecal contamination such as coliforms and faecal streptococci.

Keywords : Microbiological Pollution, Lukaya River, Fecal Coliforms, Total coliforms, Enterococci.
