Bridge Farm borehole, Machrie, Arran. Borehole geophysics equipment in use as part of an appraisal of the groundwater potential of a Permian aquifer in the west of Arran. Here, a flow impeller with conical water catcher is seen. It is used to measure flow rates within boreholes and can identify the relative amounts of groundwater entering the borehole at inflow points. A sensitive impeller sends a signal to a computer in the Land Rover where a monitor displays real time data. The meter can operate to over 400 m. depth. British Geological Survey © NERC.

Water is an abundant resource in Scotland - often it is on high quality, and on Arran, water for human consumption is extracted from Permian rocks - this is an image of the drilling of the Permian aquifer on Arran by the British Geological Survey.
