	In central and southern Scotland, 31 sites have been sampled for methane from a number of different sedimentary aquifers, mostly from the Carboniferous Clackmannan and Coal Measures groups in central Scotland. Here, groundwater was historically an important resource for industry, but today is not widely used. In southern Scotland there is local groundwater abstraction for agriculture and domestic use.

	The Clackmannan Group and Coal Measures Group form multi-layered and vertically segmented aquifers, in which fine-grained, well-cemented sandstone layers act as discrete aquifer units in which groundwater flow is predominantly through fractures, and which are separated by lower permeability siltstones, mudstones or coals. Groundwater may be present at various depths under unconfined or confined conditions, and different groundwater heads are seen in different aquifer layers. The thickness of the Carboniferous sedimentary aquifers varies from less than 500 m in southern Scotland to 3000 m in central Scotland.
