ABSTRACT: This study assesses the current and future suitability of groundwater in Limbe, Cameroon, for domestic use under the threat of climate change-induced sea level rise. Using physico-chemical analysis, the Revelle Index, and the Water Quality Index (WQI), the authors find that 23% of the groundwater is currently affected by seawater intrusion. Projections indicate that this will increase to 30.8% by 2050 and 42.31% by 2100, significantly reducing the proportion of water that is safe for drinking.
