AP Water Objective Sheet 1. 2. 3. 4. 5. Name ____________________________ Date ________________ Period _______ What does “potable” mean? How much water on our planet is potable or suitable for human use? Where is the balance of the water? What is a watershed? What watershed do we live in? Where does all the water in our watershed end up? Given any map, be able to identify upstream, downstream, river sources, river mouth and tributaries. Contrast fresh, salt and brackish water including their locations. Describe the emergent properties of water which result from its polarity (surface tension, capillarity, high heat capacity, solvent, expansion during freezing). Understand the water cycle – be able to identify and describe the following: transpiration, groundwater surface water, runoff, infiltration and condensation, recharge zone, confined aquifer, unconfined aquifer, water table. 6. 7. 8. 9. Where does Houston get its water? Why doesn’t Houston use its aquifer anymore? Describe the steps of water treatment. How are subsidence, overdraft, and salt water intrusion related to each other? Describe the issue of holding back Texas’ Colorado River in the Hill Country. Why has this decision been made? Who are the stake holders upstream and downstream and what are their concerns? How does the decision change the abiotic factors in Matagorda Bay and how is this expected to affect the biotic community? 10. What is meant by an “environmental flow” for a river? 11. Define “pathogen” and give examples of waterborne diseases. 12. What is desalination and what are the methods of desalination? Why isn’t this strategy used more often? Identify several communities which are using this strategy. 13. List the five ways to increase the water supply. Contrast advantages and disadvantages of each strategy. 14. Summarize a key lesson learned from the following case studies: The Colorado River (the one that ends in Baja Cali, not OUR Colorado ) Egypt’s Aswan High Dam; the California Water Project; The Aral Sea disaster; the Three Gorges Dam. 15. Identify the largest users of water in developed nations. In our homes, identify the biggest use of water. 16. Describe methods of water conservation in homes, cities, buildings and agriculture. 17. Describe primary, secondary and tertiary sewage treatment. 18. What happens to sewage in Houston? What new technologies are being introduced to sewage treatment? 19. Explain why and how the dead zone in the Gulf of Mexico forms each summer. What are the consequences of these zones? 20. Describe the sources, process and effects of eutrophication. 21. What is Dissolved Oxygen? Why is it so important to aquatic systems? 22. How does DO get into water? What pollutants decrease DO? 23. What is the difference between storm drains in the street and the drains that carry water from your sink? 24. What is the difference between point and non-point source pollutants? Give examples of each. 25. What is the difference between DO and BOD? Draw an oxygen sag curve to illustrate what happens to dissolved oxygen levels in streams below points where degradable oxygen-demanding wastes are added. 26. What are the three parts of the legal definition of a wetland? 27. 28. 29. 30. List several types and names of wetlands. How is a wetland the same and different from an estuary? Describe the ecosystem services provided by a wetland. Describe the ecological significance of wetlands. What is the main threat to our wetlands and how much has been lost in the US since the 1700’s? 31. What are the major categories of water pollution, where do they come from and what effects do they have? What test is used to measure each pollutant and what are ideal or normal levels for these tests?
