aluminium smelting
plant in the Qeqqata
municipality. Maniitsoq
, the second-largest town in the municipality, is one of the proposed locations, alongside the municipal center in Sisimiut
. The plant would provide employment for 600–700 people, or more than 10 percent of the population. As it is a vital decision for the town, wide public consultations were carried out in 2008–2010 by both the town authorities and the Government of Greenland in order to address potential environmental and social concerns.
A hydroelectric power plant at the river source would yield an estimated energy output of 1,000 gigawatts per year. Combined with the second plant near Kangerlussuatsiaq Fjord
with 3,170 gigawatts per year, the energy would be sufficient to power the aluminium plant near Maniitsoq. The ultimate decision as to the location of the plant has not yet been taken.
Meltwater
Meltwater is the water released by the melting of snow or ice, including glacial ice and ice shelfs over oceans. Meltwater is often found in the ablation zone of glaciers, where the rate of snow cover is reducing...

Greenland ice sheet
The Greenland ice sheet is a vast body of ice covering , roughly 80% of the surface of Greenland. It is the second largest ice body in the world, after the Antarctic Ice Sheet. The ice sheet is almost long in a north-south direction, and its greatest width is at a latitude of 77°N, near its...

Geography
Majorqaq is approximately 71 km (44.1 mi) long. The river source at 65°41′30"N 50°32′00"W is an outflow glacier draining the Greenland ice sheet, in the far inland region of the country. Majorqaq retains approximately the same width for the entire length of the river flow, from its source to its large delta, carrying large quantities of glacial siltSilt

Hunting
While the water from the river is not drinkable due to silt, the highland region around the river is used for game hunting. Due to considerable isolation of the region near the ice sheet, there is a large number of reindeerReindeer

While overall widespread and numerous, some of its subspecies are rare and one has already gone extinct.Reindeer vary considerably in color and size...
