What to Focus On
- Water pollution affects surface water, groundwater, and ocean water.
- Only a small percentage of Earth's water is usable freshwater.
- Aquifers store groundwater beneath the Earth's surface.
- Point sources come from identifiable discharge points.
- Non-point sources are diffuse and spread over land.
- Agricultural runoff is a non-point source.
- Industrial wastes may include chemicals, heat, heavy metals, and radioactive materials.
- Thermal pollution increases water temperature and reduces dissolved oxygen.
- Warm water can cause early hatching of fish eggs and lower larval survival.
Common Mistakes to Avoid
Non-point sources of water pollution are the same as point sources because both pollute water bodies.
Groundwater pollution spreads quickly because water moves underground through aquifers.
Bioaccumulation and biomagnification mean the same thing.
