L\u2019eau est une source de vie de par son caract\u00e8re indispensable et surtout pour la place importante qu\u2019elle occupe dans notre vie. Cette eau de boisson conditionn\u00e9e en sachets plastiques est tr\u00e8s pris\u00e9e par les populations du fait de son cout abordable, son caract\u00e8re rafraichissant, sa facilit\u00e9 de consommation et de son accessibilit\u00e9. Cependant, la qualit\u00e9 douteuse et le manque d\u2019hygi\u00e8ne constat\u00e9 autour de sa vente, font craindre des risques sanitaires. C\u2019est dans cette optique que nous nous sommes propos\u00e9s d\u2019\u00e9tudier les caract\u00e9ristiques bact\u00e9riologiques et physico-chimiques des eaux en sachets plastiques vendues dans la ville de Douala au Cameroun. Notre \u00e9tude quantitative transversale, \u00e0 vis\u00e9e descriptive s\u2019est d\u00e9roul\u00e9e sur une p\u00e9riode de trois mois allant d\u2019avril \u00e0 juin 2022. Notre \u00e9tude a consist\u00e9 \u00e0 recenser 25 soci\u00e9t\u00e9s de fabrication correspondant \u00e0 25 marques d\u2019eau en sachets plastiques dans la ville de Douala. Ces eaux en sachets plastiques ont \u00e9t\u00e9 analys\u00e9s par la m\u00e9thode de filtration sur membrane pour la bact\u00e9riologie et la spectrophotom\u00e9trie par absorption mol\u00e9culaire atomique pour la physico-chimie. Les donn\u00e9es compil\u00e9es sur des fiches ont \u00e9t\u00e9 ins\u00e9r\u00e9es dans Microsoft Excel 2013 et analys\u00e9es \u00e0 l\u2019aide du logiciel SPSS.25.0 La turbidit\u00e9 \u00e9tait non conforme pour toutes nos eaux (100 %). Parlant des solides totaux dissous, 100% des eaux en sachet \u00e9taient non conformes. Nous avions not\u00e9 la pr\u00e9sence des m\u00e9taux lourds dans nos eaux tels que les ptalates et le bisph\u00e9nol. Toutes nos eaux \u00e9taient non conformes aux ptalates. En ce qui concerne les param\u00e8tres bact\u00e9riologiques, toutes les marques d\u2019eaux en sachets \u00e9tudi\u00e9es \u00e9taient contamin\u00e9es soit par les coliformes f\u00e9caux, les coliformes totaux, les BHAM ou les trois groupes de germes \u00e0 la fois. Les taux de non-conformit\u00e9 des param\u00e8tres bact\u00e9riologiques et physico-chimiques sont tr\u00e8s \u00e9lev\u00e9s. Ces eaux en sachets plastiques constituent un danger pour la sant\u00e9 des populations.<\/header>\n

Water is a source of life because of its indispensable nature and especially for the important place, it occupies in our lives. This drinking water, packaged in plastic bags, is highly prized by the population because of its affordable cost, it\u2019s refreshing character, its ease of consumption and its accessibility. However, the dubious quality and the lack of hygiene around its sale raise fears of health risks. With this in mind, we proposed to study the bacteriological and physico-chemical characteristics of water in plastic bags sold in the city of Douala in Cameroon. Our quantitative, cross-sectional, descriptive study was conducted over a three-month period from April to June 2022. Our study consisted in identifying 25 manufacturing companies corresponding to 25 brands of water in plastic bags in the city of Douala. These plastic sachet waters were analysed by the membrane filtration method for bacteriology and atomic molecular absorption spectrophotometry for physico-chemistry. The data compiled on sheets were inserted into Microsoft Excel 2013 and analysed using SPSS.25.0 software. Turbidity was non-compliant for all our waters (100%). Speaking of total dissolved solids, 100% of bagged water was non-compliant. We noted the presence of heavy metals in our waters such as ptalates and bisphenol. All our waters were non-compliant for ptalates. Regarding bacteriological parameters, all brands of sachet water studied were contaminated with either faecal coliforms, total coliforms, BHAM or all three groups of germs at the same time. The rates of non-compliance of bacteriological and physico-chemical parameters are very high. This water in plastic bags constitutes a danger for the health of the population. <\/em><\/p>\n
