Groundwater science
We provide long-term, groundwater-related expertise in hydrogeology for the benefit of both the UK and the rest of the world. Our research addresses issues related to:
- the sustainability of water resources and quality
- the effects of environmental change on the water cycle
- natural hazards in the context of groundwater
- groundwater and human health
We undertake groundwater-related monitoring and surveys, and hold extensive hydrogeological data and information. In collaboration with our partners, we undertake integrated catchment studies through field sites and novel monitoring technologies, groundwater models and supporting services and analytical facilities.

Miriam Sogoba is watering her market garden in the Segou region of Mali. This is part of a women’s association of 45 women. As well as pumping the groundwater, they monitor the rainfall and groundwater levels to help sustainability manage the water. “Since I joined the market garden. The money I have gained from the sale of vegetables has helped so much – buying clothes for the children and helping me buy a sheep and a goat”. © WaterAid – Segou region, Mali – Basile Ouedraogo
Groundwater science at BGS
Projects
Explore our current groundwater research projects.
Data
BGS is the national repository for groundwater data and information for the UK and has extensive holdings of international groundwater data and information.
Services
We provide a comprehensive suite of hydrogeological field services from borehole drilling to tracer tests.
Quality
The quality of groundwater determines its value as a resource and its impact on surface water ecosystems.
Energy
How groundwater can be used for geothermal energy and the effects of hydrocarbon exploitation on groundwater.
Resources
BGS research into all aspects of groundwater flow, recharge and discharge improves our understanding of this precious resource.
Extremes
Groundwater flooding and drought, and the processes that affect groundwater catchment areas.
International
BGS has a long history of international development activity throughout the world to sustainably develop and manage groundwater.
