What is acid rain?

• Precipitation that is unusually acidic and can have harmful effects on plants, aquatic animals, and infrastructure

• A rapid increase or accumulation in the population of algae in a water system

• An underground layer of water-bearing permeable rock from which groundwater can be extracted

• Contamination of water by harmful bacteria

What is eutrophication?

• Contamination of water by excessive nutrients and bacteria.

• Pollution by sand, soil, and other minerals that are washed into streams and rivers after rainfall

• Contamination of water by materials that cause death, disease, or birth defects

• The process by which a body of water acquires a high concentration of nutrients depleting the water of oxygen which causes death of organisms in the water.
