Industrial Discharge Sites

Industrial activities generate waste which is discharged into water bodies, the air or ends up in landfill sites. The wastes are usually processed to some degree. Industrial wastes discharged into the air and water can disrupt ecosystems. For example, waterborne toxic contaminants from industrial sources has been one of the major causes of the degradation of the Great Lakes. Acid precipitation originating from industrial sources and automobiles and has been responsible for acidifying thousands of lakes in North America. An indirect indicator of threats to ecosystems and species is the concentration of major industrial sites that discharge airborne pollutants such as SO2 and NO2 . Industrial discharge sites are concentrated in southern Ontario and Quebec, on the west coast near Vancouver, and around major cities in British Columbia and the Prairies.
