Hydrochimie, qualite physico-chimique et bacteriologique des eaux de la partie nord de brazzaville (republique du congo)
The present study is based on the evolution of the physico-chemical and microbiological quality of surface and groundwater used for the daily needs of populations in the northern part of the Brazzaville region. The physico-chemical study of groundwater and surface water revealed that these waters are soft, weakly mineralized and that the alkalinity of these waters would be essentially dominated by bicarbonate ions (HCO3-).
