Water supply is a global problem. A study was conducted on twelve (12) traditional wells water in Daba Dagnogo and Gnipi 2 to determine their physico-chemical quality. Two sampling campaigns (dry season and rainy season), were performed on 16 physical and chemical parameters. The results show that the water is acidic with an average pH of 6.41 ± 0.4; moderately mineralized with an average conductivity of 731.14 ± 611.98 μS·cm^-1; moderately saline with an average rate of 1.56 ± 1.22. The average temperature of 28.07 ± 0.86°C is above the norm for all wells. All major ions are consistent with WHO standards except calcium and potassium. 41.67% of wells exceed the standard ammonium ion whose average was 1.43 ± 2.79 mg·L^-1 nitrate and 100% with an average of 492.42 ± 434.02 mg·L^-1. The ion concentrations are highest in the urban area and are higher in the dry season. The quality of the water sampled wells deteriorated. Several factors affect the degradation, namely the shallow wells, their proximity to toilet, the lack of sanitation and poor management of household waste. It will carry out a campaign to educate people to protect the immediate environment of the water points, avoiding the deposit of garbage and to provide the appropriate wells lids.
