Glasgow is one of many locations within the United Kingdom once dotted with a number of thriving coal mines. Before the suitability of the water stored in mines can be determined for use in ground source heat pump (GSHP) heating applications, it is essential to rule out any risk of contamination caused by exposure to this water. This study examines water samples obtained from boreholes drilled directly above abandoned and flooded mine workings. It indicates that the chemistry of the water flooding the mines beneath Glasgow is suitable for use in GSHP heating applications. The development of such systems in the future could help bring Glasgow forward in its ambition to become one of Europe’s top 10 sustainable cities by the year 2020, as well as helping to transform previously neglected and impoverished areas of the city, to areas full of potential by creating a number of jobs, homes and opportunities for the people living in this area. </jats:p
