Fluoride levels in groundwater may cause either enamel fluorosis or dental caries depending on their concentrations when consumed. Research has shown that an estimated 60 % of the total intake of fluoride is through drinking water (Selwitz et al, 2007). Boreholes sunk in the West Gonja district had their groundwater analyzed for fluoride. Using World Health Organisation (WHO) standard of (0.5-1. 5 mg/l) as basis, result revealed that concentration deviates from standard set by WHO. Test boreholes drilled in the communities showed three broad categorisations of fluoride levels in the groundwater as;
