“…Fluorides in drinking water at minimal concentration of 0.5 mg/L is responsible for the development of healthy teeth and bones especially in children [11,12]. However, high levels of fluorides in drinking water resources is hazardous to human health and can induce numerous serious health problems such as dental and skeletal fluorosis [13]. Fluorosis has become a serious health concern having affected more than twenty nations in Africa and Asia as the most affected continents [14].…”

Aims: The objective of this study was to determine the levels of fluoride in borehole water samples. Study Design: The total of eight samples were collected from five villages in Chiradzulu and transported in cooler ice-bath to the laboratory for the analysis. Place and Duration of Study: The study was conducted in the Department of Chemistry and Chemical Engineering Laboratories, at University of Malawi in the month of June. Methodology: The ion selective electrode technique was used to assess fluoride levels. Physicochemical water parameters were measured with multi-meters. Results: The results obtained ranged from 2.26 to 3.08 mg/L, 136 to 561 mg/L, 261-1212 μs/cm and 6.27 to 6.97, for Fluorides, TDS, conductivity and pH, respectively. Levels of fluorides exceeded permissible limits for borehole water established by WHO and were below the standards for MBS Conclusion: The results attained in the scope of the study support coloration of teeth observed amongst individuals in study communities, helping to understand that groundwater is not suitable for consumption. Therefore, the study provides recommendation for urgent implementation of defluoridation measures to provide clean and safe water for the existing community members.
