Table 1_Geochemical processes, sources, and health implications of fluoride-rich groundwat

Thirty-six borehole water samples from the central Volta River Basin in northern Ghana were analyzed for fluoride (F⁻) concentrations and hydrogeochemical characteristics. The dataset, authored by Moses Boakye Okyere and last updated in April 2026, includes fluoride levels ranging from 0.2 to 19.5 mg/L, with a mean of 4.3 mg/L, and associated health risk calculations for different demographic groups.

Use Cases

• Map spatial distribution of fluoride contamination based on the described elevated concentrations in the northeastern fringe.
• Assess human health risks using the provided hazard quotient (HQ) values for infants, children, teenagers, and adults.
• Identify hydrogeochemical processes controlling fluoride enrichment based on described mechanisms like water-rock interaction and mineral dissolution.
• Evaluate groundwater suitability for drinking by comparing fluoride levels against the WHO guideline limit of 1.5 mg/L.

Strengths

• Includes specific fluoride concentration statistics: range (0.2-19.5 mg/L), mean (4.3 mg/L), and exceedance rates (84% above WHO limit).
• Health risk assessment is provided for four demographic groups with calculated hazard quotient (HQ) values.
• Data is openly licensed under CC-BY-4.0.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (34.5 KB), indicating limited scope.
