1. 6-N.I.M.B.Y. – There is No Away in Throwing CFC’s break down the ozone layer – Why is this a problem?

2. Pollution in Surface Waters Methods for killing viruses and bacteria in polluted water. – Chlorinating water (may cause cancer-causing agents) – High-intensity ultraviolet light

3. Pollution in Ground Water Pollution from farmers seeps into soil and contaminates ground water. Contaminates aquifers

4. Biodegradable substances – organic substances broken down by bacteria, fungi, or other organisms. Table 3.6 Are all substances biodegradable if they say they are?

5. Hazardous Wastes Hazardous household wastes Table 3.7

6. 4 R’s Reduce, Reuse, Recycle, Recover – These R’s are ranked from best strategy to worst.

7. Sanitary Landfills Covered to avoid windblown litter and attract scavengers. Consist of mostly organic materials

8. Produces high amounts of leachate (a liquid that results from decomposition – Filtered out and sent to water treatment centers

9. Anaerobic conditions produce methane and carbon dioxide. – Methane burned off in a controlled manner to prevent explosions.

10. Secure Landfills Landfills that are covered once they are full and have wells drilled in them so they can be monitored for leakage from the site Store hazardous and toxic wastes.

11. Bioremediation – removal of contaminants from the soil by living things. – Eg. Sunflowers break down radiation into non- harmful chemicals and deposit them in the soil.
