CHAPTER 17 WATER USE AND MANAGEMENT

Chapter Overview


Water is a vital resource that is essential to life. Where water is stored on Earth is
important to the study of AP Environmental Science. Knowing that agriculture
uses the greatest amount of water worldwide is fundamental information. Dams
provide both benefits to humans and causes problems for people as well as
ecosystems. Issues surrounding water diversion projects are very significant
ideas. Conservation is a topic that will become increasingly important to the
study of Environmental Science.

Water Diversion Activity
 In this activity, the students will be assigned a specific water diversion project.
Both the historical significance of the project along with the future implications
of the project will be investigated. The students can either make a poster or a
PowerPoint of their particular project. Students should include a cost/benefit
analysis from both an economic and environmental standpoint.

Cornell Questions for Review and Powerpoint
1. What activity, in the United States, accounts for the largest water
consumption? In the world?

2. What three factors control global water deficits and surpluses?

3. What is an aquifer? How does it function to maintain water supplies?

4. What are water diversion projects? How are they useful in providing
freshwater? How are they harmful to natural ecosystems?

5. One of the suggestions for conserving water is, “Don’t dump anything down a
storm sewer that you wouldn’t want to drink.” How does the message in the
statement relate to the hydrologic cycle?

 Free-Response Question:
Directions: Answer all parts of the following question. Where explanation or
discussion is required, support your answers with relevant information and/or
specific examples. When a calculation is required, be sure to show how you
arrived at your answer.
1. The Leaky family is comprised of 4 individuals. Each person showers daily for
5 minutes. Their shower head flows at 20 gallons per minute. The price of
their water is $0.10 per 100 gallons.
(a) How much water does the family use showering daily?
(b) Calculate the cost of the family’s showers for one month (assume a 30-day
month).
(c) Suppose the family has a “leaky” faucet. The faucet leaks at a rate of 1 drop
per second. 5 drops equal 1 mL. Calculate the volume of water wasted
from the leaky faucet in one minute.
(d) Describe THREE actions the family can take to conserve water.
