Mine water characterisation and monitoring borehole GGA07, UK Geoenergy Observatory, Glasgow

This report and accompanying data release describe the ‘as-built’ borehole GGA07 at the UK Geoenergy Observatory in Glasgow. They also describe initial hydrogeological testing completed after borehole construction and provide an initial geological interpretation. Mine water borehole GGA07 at the UK Geoenergy Observatory in Glasgow is screened across the Glasgow Upper mine working and its overlying siltstone/ claystone roof. The mine working is interpreted to be a coal stoop (pillar) and room. Initial hydrogeological indications from the borehole test pumping suggest that borehole GGA07 is very high yielding. Borehole GGA07 has ERT and DTS cables installed between the borehole casing and the surrounding rock, and a hydrogeological data logger installed within the borehole.
