Water Pollution in Canada Water pollution is the contamination of bodies of water because pollutants are directly or indirectly discharged into the water without adequate treatment to remove said pollutants. It can branch out into different areas including acid rain, erosion and sediment, groundwater contamination, and wastewater. Acid rain is rainwater in which the acidity is increased by sulphur and nitrogen oxides in the atmosphere, which are most likely caused by industrial and vehicle emissions. The chemicals combine with the water in the atmosphere to form sulphuric and nitric acids. This is when precipitation takes place and the acids become considered acid rain. Acid rain on the pH scale is valued around 5.3. (Government of Canada) The main cases of sulphuric acid in Canada are metal smelters and coal-fired generators. Coal-fired generators produce nitrogen oxides along with motor vehicles. Acid rain affects water quality when the acidic components either directly disturb the water or indirectly by first encountering other ecosystems before the aquatic system. When the acids interact with the terrestrial ecosystem it creates a chemical change and later affects conditions in lakes or other larger bodies of water.
This then creates difficulties for the reproduction of aquatic plants and animals. By affecting the reproduction of animals it also changes the food chain as animals rely…
