Water Use, Management, and Pollution Review

1. Define evaporation, condensation, precipitation, runoff, infiltration, humidity, relative humidity, watershed, capillary water, ground water, seep, percolation, transpiration, water table, aquifer, recharge area.

2. Describe the water cycle using as many terms from question 1 as possible.

3. How do wetlands act as natural reservoirs to moderate the flow of streams and rivers during wet and dry periods? What impact will the development of wetlands have on water quality and quantity?

4. How does deforestation impact the water cycle?

5. What is the effect of paving on the water cycle?

6. What are the three major categories of water use? From what point in the cycle is water generally withdrawn for use? How is it withdrawn and used?

7. What are the results of overdrawing groundwater? Surface water? Describe the human, ecological, and environmental results of each.

8. Compare the potential of increasing water supply to that of reducing demand.

9. How can water demands be reduced in industry, agriculture, and households?

10. What are some possible sources of increased water?

11. Describe both phytoplankton and SAV. Where does each get nutrients and light?

12. Describe and contrast an oligotrophic and a eutrophic lake. Describe the major producers, nutrient content, turbidity, and dissolved oxygen content of each.

13. Describe the process and results of eutrophication.

14. Why is the natural state of waterways to be oligotrophic?

15. What is BOD? How is it a measure of water quality?

16. Distinguish between natural and cultural eutrophication.

17. Describe the effect of sediments on waterways and eutrophication.

18. Describe some ways by which the results of eutrophication can be addressed. Indicate the costs and benefits of each.

19. How can the causes of eutrophication be addressed? Indicate the costs and benefits of each.

20. Describe the role played by wetlands in preventing eutrophication.
