BGS has produced a suite of hydrogeological maps of Scotland. The suite comprises the following layers:

  • groundwater vulnerability
  • aquifer productivity (bedrock and superficial)

The groundwater vulnerability map shows the relative vulnerability of groundwater at the uppermost water table to contamination. Groundwater vulnerability is the tendency and likelihood for general contaminants to move vertically through the unsaturated zone and reach the water table after introduction at the ground surface.

The aquifer productivity maps describe the potential of bedrock and superficial deposits aquifers across Scotland to sustain various levels of borehole water supply, and the dominant groundwater flow type in each aquifer. They have been used to help characterise groundwater bodies as required by the Water Framework Directive, and are also useful in policy development to prioritise water supply and site investigations, to inform planning decisions, and to improve awareness of groundwater in general.
