  2. Wastewater treatment - 100 Waste water treatment plants treat sewage water along with this type of water. Storm water

  3. Wastewater treatment - 200 Primary treatment in waste water treatment is this type of process Physical

  4. Wastewater treatment - 300 Secondary treatment in waste water treatment is this type of process Biological

  5. Wastewater treatment - 400 The main purpose of the aeration tank in secondary treatment is to remove this type of pollution Dissolved organic matter

  6. Wastewater treatment - 500 • Chlorine has traditionally been used as a final disinfectant. However many cities are now starting to use other methods. Name one example. UV rays, ozone gas

  7. Litho and Atmosphere - 100 The layer of the atmosphere where weather occurs. Troposphere

  8. Litho and Atmosphere - 200 The layer of the atmosphere that is important in blocking the sun’s UV radiation. Stratosphere

  9. Litho and Atmosphere - 300 This class of compounds once used in refrigerants have the ability to breakdown “good” ozone CFC’s (chloroflourocarbons)

  10. Litho and Atmosphere - 400 Produced when several pollutants from automobile exhaust are acted on by sunlight. Photochemical smog

  11. Litho and Atmosphere - 500 International protocol that calls for a reduction of CO2 levels to below 1990 levels. (The US has decided to not sign on to this agreement) Kyoto Protocol

  12. Water - 100 What percentage of the water on Earth is freshwater (liquid and solid)? 2.5 – 3.0 %

  13. Water - 200 This activity uses the most water worldwide. Agriculture (irrigation)

  14. Water - 300 Water held in the soil and taken up by the roots of plants Capillary water

  15. Water - 400 This is the main reason why the Aral Sea has decreased by 60% Diverted to irrigate cotton fields

  16. Water - 500 The depletion of groundwater from aquifers and the building of levees preventing seasonal flooding can result in this problem. Land Subsidence

  17. Water Pollution - 100 Build up of this pollutant along a food chain is what leads to Minimata disease which is also known as “dancing cat” disease Mercury

  18. Water Pollution - 200 She fought for the people of Hinkley, CA against PG&E whose use of hexavalent chromium contaminated the groundwater in the town Erin Brokovich

  19. Water Pollution - 300 The increase in concentration of a pollutant from one link in a food chain to another Biomagnification

  20. Water Pollution - 400 These man-made chemicals which were once used in materials for making insulation, coolants, and lubricants in transformers were found to harm wildlife in Puget Sound and other areas PCBs

  21. Water Pollution - 500 DAILY DOUBLE !!!

  22. Potpourri - 100 This gas/molecule is needed and used up during the process of cell respiration and decomposition O2 - oxygen

  23. Potpourri - 200 Water pollution that is easy to identify the source, such as a factory is defined as this type of pollution Point-source pollution

  24. Potpourri - 300 This is a common water quality test that suggests that water is contaminated by animal waste Fecal coliform test

  25. Potpourri - 400 This is the largest aquifer in the US Ogalalla aquifer

  26. Potpourri - 500 This is the largest dam in the world The Three Gorges Dam in China

  27. Earth and Geo - 500 Water Pollution - 500 Double jeopardy This activity is the predominant cause of thermal pollution in surface waters Power (electrical) plants
