To mitigate the disasters caused by the consumption of poor quality of water, the World Health Organization (WHO) has established standards for testing the quality of drinking water that must be met. The purpose of this study is to verify the relevance of these tests in crystalline basement aquifers in equatorial areas. The global analysis of water quality was conducted by comparing the measured concentration of iron, calcium, pH change and other major ions in the 70 water samples which were collected at different sites in the Centre Cameroun area with the WHO standards. The water quality index was estimated in the entire area using the block ordinary kriging technique. The results show a high concentration of iron, a very high or very low pH, and high temperature values at certain sites, exceeding sometimes the standard values. Finally, this study shows that the control of groundwater quality following WHO standards must always be conducted.
