DRILLING for a borehole that will allow scientists to “see” underground has been started.

The 7.5m drilling rig is at the UK Geoenergy Observatory in Glasgow.

Over the next 15 months, the drilling team will create 12 boreholes of various depths, which will enable research into Glasgow’s geology and its underground water systems.

Scientists want to find out if there is a sustainable mine water resource that could provide a low cost, low carbon heat source.
