Study improves water quality assessment in Nigeria and Ghana, suggesting a better decision support system.
). In Nigeria, Water Quality Index (WQI) eclipsing errors were reduced, improving hazard detection accuracy. In Ghana, parameter prioritization within the Pollution Index of Groundwater (PIG) was refined. The method provides an accessible, reproducible tool for water quality weight assignment and intensity-based pollutant ranking, supporting environmental toxicology and hazard assessment. Its operational simplicity suits diverse monitoring regimes, offering managers a practical approach for equitable, targeted water quality assessment. This work advocates for more reliable water quality assessment to enhance attainment of multi-sustainability goals.
