| Summary: | This twelfth environmental monitoring programme was conducted in the Nalunaq area, about 40 km from Nanortalik, South Greenland, from 18-31 August 2015. The environmental monitoring programme is conducted to discover and avoid unwanted environmental impacts of the former mining industry. Since the monitoring in 2014, the area has been without any activity. The mining company Angel Mining Gold A/S closed its gold production in November 2013 where after the Nalunaq area was affected by decommissioning and restoration until August 2014. The gold was extracted by chemical extraction with cyanide (carbon-in-pulp). Due to the use of cyanide to extract gold from the ore, there was strict monitoring with the outflow of cyanide from the mine to the valley during the production period, and monitoring will continue for 5 years after the closure. Also, extensive monitoring is conducted to reveal release of metals into the Kirkespir Valley and Kirkespir Bay environment. The content of metals in the terrestrial, freshwater, and marine environment in the Kirkespir Valley and Bay is decreasing and is considered minor. DCE/GINR assess that no requirement for further actions to reduce the environmental impact is needed. Environmental monitoring will continue in 2016 and 2019. |
