Artesian flowing, borehole drilled into the Permian sandstone aquifer at Machrie, Arran, Bridge Farm borehole, Machrie, Arran

Bridge Farm borehole, Machrie, Arran. An artesian, flowing, borehole drilled into the Permian sandstone aquifer at Machrie, Arran. A T.V. log of the borehole is being undertaken, using a BGS Land Rover. The flow of water was measured at 10 litres/second, which makes it one of the highest naturally-flowing boreholes in Scotland. Most of the water is coming into the borehole at depths between 65 m. and 95 m. below ground level. The quality of the water is very high, and it is hoped that West of Scotland Water will use this source for most of the island's water supply before 2002. 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.
