Water Quality

According to the UN’s Intergovernmental Panel on Climate Change, temperatures in the Arctic are rising about twice as fast as the global average. This rapid change in temperature is expected to impact the biodiversity and hydrology of Arctic streams and rivers. Increased water temperature causes shifts in aquatic ecosystems and can favour the growth of temperature sensitive water-borne bacteria and aquatic plants (algae) which could potentially pose health risks.

Untreated natural water from local lakes, streams and rivers are important sources of water for northern communities. Many Nunavut residents perceive these sources to be healthier and cleaner than chlorinated tap water. However, there is little regular monitoring of the streams and rivers to verify the water quality over time. Community members wonder how changes will affect the quality of drinking water from these sources. Many regions are also interested in monitoring microbes and contaminants and are concerned at the potential health risks that they may pose.
