O knihe
The availability of good quality water in sufficient quantity for the entire population of Ouessè is one of the current issues. The objective of this study is to analyze the quality of well water in the study area through certain physical, chemical and bacteriological parameters. Standardized methods as well as spectrophotometer and titrimetric analysis, and membrane filtration using Chrom-Agar as the culture medium, were used for physical, chemical and bacteriological analyses respectively. A total of 189 wells were inventoried as sources of drinking water, and 378 people were surveyed. Among the wells inventoried, ten (10) were selected, with at least one water sample per district, for the various analyses. The results of the analyses revealed that 9/10 of the samples were physicochemically polluted. The microbial germs sought (total coliforms and Escherichia-coli) were highly present.
