As of 2021, the Kpong and Sogakope rivers in the main and lower Volta basins in Ghana registered the highest water quality index scores. These reached 82.11 points and 81.14 points, respectively, meaning that their water quality was good or unpolluted. Rivers in the country with fairly good water quality included Ajena, Bamboi, and Daboya, all in the Volta basin. The index measures the quality of surface water, where, for instance, scores between 25 and 50 indicate poor quality of water, and scores greater than 80 points represent good or unpolluted water.
