Hydrogeological typologies of the aquifer systems underlying Lagos State, Nigeria

This report is the published product of a study by the British Geological Survey (BGS) in partnership with Cardiff University, Aberdeen University, the University of Lagos and the University of Ibadan to develop a Groundwater Demonstrator for Lagos. The report aims to present the current conceptual understanding of groundwater systems underlying the state by compiling all pre-existing and openly accessible groundwater data and research, which was then supplemented by groundwater level data and key water quality parameters collected by the University of Ibadan and the University of Lagos at 44 sites across Lagos State since 2021. Results from this study can be used to inform future hydrogeological investigations across the state, allowing for stakeholders to better understand, monitor and manage the state’s groundwater resources.
