A contaminant is a substance that is found in a place where it should not be. This does not necessarily mean that it is harmful, but depending on what it is and the amount that is present, it may be. The types of contaminants that are found in the Canadian North include: Persistent Organic Pollutants (POPs), a group of mostly humanmade chemicals which include organochlorines (OCs) and can stay in the environment for many years without changing. POPs can be transported long distances in the atmosphere and ocean. Heavy metals such as mercury, cadmium, and lead; and Radionuclides such as cesium, strontium, and polonium.

Any physical, chemical, biological, or radiological substance added to water which makes water impure.

Constituents added to the water supply through use.

Unwanted and potentially detrimental organic, inorganic and biological substances.

Chemical Pollutants

A contaminant is a substance that is found in a place where it should not be. It may not be harmful but it could be depending on what it is and the amount that is present. The types of contaminants that are found in the Canadian North include: Persistent Organic Pollutants (POPs), a group of mostly human-made chemicals which can stay in the environment for many years without changing. They can be transported over long distances in the atmosphere. Heavy metals such as mercury, cadmium, and lead. Radionuclides such as cesium, strontium, and polonium. DDT DDT stands for dichlorodiphenyltrichloroethane. It is a POP developed in the 1940s to kill lice and to kill biting insects that carry diseases such as malaria, yellow fever and typhus. DDT was heavily used to kill insects feeding on crops in the 1950s and 1960s in the Great Lakes region until it was found to be harmful to other forms of life. DDT is banned in Canada.
