Greenland Ice Cap Water:Technical Report on five potential locations for meltwater export
Meltwater from Greenland is an increasingly attractive resource of pure freshwater. To at-tract investments from the industry, an extensive effort has been launched to map possible extraction locations, determine the quality of the meltwater, and review the existing ice and water export legislation....

Meltwater from Greenland is an increasingly attractive resource of pure freshwater. To at-tract investments from the industry, an extensive effort has been launched to map possible extraction locations, determine the quality of the meltwater, and review the existing ice and water export legislation. This report presents results from mapping- and water quality anal-ysis of five selected locations, visited by boat in June 2017. Two locations drain ice sheet catchments and three locations drain catchments with local mountain glaciers. The mapping includes catchment delineation, ice- and land runoff modelling, ice-dynamic modelling of the age of the melting ice, collection of fjord depth data and an assessment of the risk from glacial lake outburst floods. An extensive analysis of chemical, physical and microbiological parameters were performed on the water samples collected during field-work. Some types of analysis had to be performed on-site, some were performed at GEUS laboratories, and some at certified commercial laboratories.
