Hydrogeological Maps (BGS)
Hydrogeological maps at a national scale for England & Wales and Scotland bring basic geological information together with data on the hydraulic and hydrochemical characteristics of the rocks and their usefulness for groundwater supply.
The resulting 23 maps display information on surface water features, the 3D geometry of aquifers, groundwater levels, abstractions and water quality including saline intrusion in varying amounts of detail. They range in scale from 1:625 000 for the national maps of the hydrogeology of England & Wales, and Scotland down to 1:25 000 for some smaller regional maps.
The BGS also hold a limited collection of international hydrogeological maps from all parts of the world.
