Cette étude a évalué la qualité des eaux souterraines de la communauté de Nkoro, dans l’État de Rivers, au Nigeria, afin de prévenir l’apparition de maladies transmises par l’eau. Les échantillons d’eau ont été prélevés dans des sources d’eau potable sélectionnées, notamment un puits creusé à la main et des forages. Les échantillons d’eau ont été prélevés à six endroits différents et leur qualité a été évaluée pour les saisons sèches et humides à l’aide de la méthode standard d’analyse de l’eau de l’American Public Health Association. Les indices de qualité de l’eau (IQE) ont été calculés pour les sept (17) paramètres suivants : pH, conductivité électrique, total des solides dissous, total des solides en suspension, turbidité, demande biochimique en oxygène, oxygène dissous, demande chimique en oxygène, sulfate, phosphate, nitrate, dureté totale, calcium, magnésium, alcalinité, couleur et chlorure. Les métaux lourds et certains paramètres microbiens ont montré des différences significatives qui étaient supérieures aux limites des normes réglementaires de l’Organisation mondiale de la santé (OMS) et de la Standard Organization of Nigeria (SON).
