Fluoride contamination in groundwater remains a major public health challenge in northern Tanzania, particularly in Oldonyosambu and Oldonyowas wards of Arusha District. Many residents depend on groundwater sources with fluoride levels exceeding WHO’s recommended limit (1.5 mg/L), leading to widespread dental and skeletal fluorosis. Rainwater harvesting (RWH) offers a low-cost and sustainable alternative for providing safe drinking water in these communities.
