In 2015, Ghana launched the National Drinking Water Quality Management Framework (NDWQMF) to promote a risk-based approach to water quality through water safety plans (WSPs). This study uses a narrative review to synthesize WSP implementation progress in Ghana, identify gaps in practice, and provide recommendations for enhanced effectiveness and scale-up. Findings show limited uptake: only three of 88 urban water supply systems have adopted WSPs, while in the rural sector, the Community Water and Sanitation Agency has implemented WSPs in 177 of 1,022 small-town systems, and the safe water network in 46 systems.

Drinking water in Ghana is estimated at 79%, but this only represents the proportion of the population with access to improved drinking water sources without regard to the quality of water consumed. This study investigated the quality of household drinking water sources in the Oforikrom municipality where potable water requirements are on the rise due to an ever-increasing population. Both quantitative and qualitative methods were employed in this study.

This study investigated the effects of two mostly improvised chemical additives, calcium carbide and lambda super 2.5 EC (LSEC), on the physico-chemical and microbial characteristics of faecal sludge from toilets. The quality of faecal sludge was assessed before and after application of the chemical additives in an experimental setup of ten different treatment units including a control, and treatment replicates.
