Study of the physico-chemical properties of the basement aquifer in the rural commune of Ampangabe, Ambohidratrimo district

geology, hydrology and meteorology

As the rural commune of Ampangabe is an agricultural zone, the use of chemical fertilizers could have an impact on the quality of well water in the surrounding area. In addition, the general environment of the wells is unsanitary, despite the fact that 50% of the population consume well water in the commune. This study involves the physico-chemical characterization of well water in the fokontany of the rural commune of Ampangabe, as the water table is drying up. Hence the research question: is the water table in the Ampangabe rural commune vulnerable to external pollutants? The results showed that only one of the five wells analyzed complied with sanitary standards. The obsolete and unhealthy state of the infrastructure is one of the main causes of this situation; but other factors can also be considered, such as the use of chemical fertilizers and the presence of a processing industry, which are sources of pollution. Short-, medium- and long-term priority actions need to be identified to avoid the various diseases that are one of the sources of poverty among the population
