Question 2
During coal and metal mining, waste water can flow from the mine into nearby rivers. Sometimes this waste water is highly acidic. It pollutes the river and kills aquatic plants and animals. It also corrodes buildings and bridges along the river. This photograph shows how a mine spill has polluted the Animas River in Colorado.
How can we reduce the acidity of the river water so that aquatic life is not further harmed?
