Abstract
The environment (middle) of three important sites of catchment of water of the REGIDESO in Kinshasa notably the rivers N’djili and Lukunga and the Congo stream is in particular vulnerable following the failure to respect of the environmental hygiene by the riparian populations of these three sites and of all kinois in general. This survey proposes to verify the degree of water pollution treated by the REGIDESO and the efficiency of the treatment techniques applied by this one to purify water. For that to make, 3 samples by site of the raw water and three of water treated have been appropriated and have been analyzed in order to determine the physic-chemical parameters (MO, MES, Turbudité, pH, T°, SD, Co, NO-3, PO 4, FeT, Pb, OD, DBO5 and DCO) and bacteriological (fecal coliforms, fecal streptococci and Escherichia Colis) for the raw water, while for the treated water, it has about of the analysis of the data base of the laboratory of the REGIDESO. The gotten results show that the dismissals descended of the human activities upstream of the sources of catchment have negative impacts on water to treat and that some parameters as the total iron, the DCO and the MY don't answer the norms of the drinking water.

Abstract: (french)
L’environnement (milieu) de trois sites importants de captage d’eau de la REGIDESO à Kinshasa notamment les rivières N’djili et Lukunga et le fleuve Congo est vulnérable suite au non-respect de l’hygiène environnementale par les populations riveraines de ces trois sites en particulier et de tous les kinois en général. Cette étude propose d’identifier les polluants potentiels de ces trois sites, de vérifier le degré de pollution de l’eau traitée par la REGIDESO et l’efficacité des techniques de traitement appliquées par celle-ci pour purifier l’eau. Pour ce faire, six échantillons de l’eau brute par site et six de l’eau traitée par usine ont été prélevés et analysés en vue de déterminer les paramètres physico-chimiques (MO, MES, Turb., pH, T°, SD, Co, NO-3, PO-4, FeT, Pb, OD, DBO5 et DCO) et bactériologiques (coliformes fécaux, streptocoques fécaux et Escherichia Coli) pour l’eau brute, tandis que pour l’eau traitée, il a s’agit de l’analyse de la base de données du laboratoire de la REGIDESO. Les résultats obtenus montrent que les rejets issus des activités anthropiques en amont des sources de captage ont des incidences négatives sur l’eau à traiter et que certains paramètres tels que le fer total, la DCO et les MES dans l’eau traitée ne répondent pas aux normes de l’eau potable. Par ailleurs, l’examen minutieux sur une période d’un an des archives du laboratoire de la REGIDESO indique certaines défaillances temporaires, journalières ou périodiques quant à la bactériologie.
