Geospatial mapping reveals high nitrate levels and toxicity in groundwater, indicating urgent need for sustainable practices.

This research aims to assess the health impacts of nitrate-contaminated groundwater across different age groups in Ghana.
Used physicochemical analysis to assess water quality
Applied USEPA health risk models
Employed ArcGIS-based geospatial mapping to identify contamination clusters
Evaluated exposures across six age groups from infants to elderly
Nitrate concentrations in agricultural zones reach 720 mg/L; 30.6% of samples exceed the 50 mg/L guideline
41.7% of infant samples show oral hazard quotients exceeding safe levels
Total hardness in many samples exceeds 100 mg/L, posing potential dermatological implications
Geospatial mapping highlights contamination hotspots, intensifying environmental justice concerns for rural communities

Agbasi et al. (2026) studied this question.
