About This Chapter
Water Issues & Conservation - Chapter Summary and Learning Objectives
Lessons in this chapter begin by discussing the importance of water in sustaining plant and animal life. You can also learn about some of the techniques used to conserve and store this resource along with their benefits and drawbacks. The environmental protection laws in place to ensure the quality of our drinking water are covered as well. After completing this chapter, you should be able to identify:
- The effects of surface and groundwater depletion
- Methods for sustainable water use
- Sources of water pollution
- Water treatment techniques
|Cycles of Matter: The Nitrogen Cycle and the Carbon Cycle||Describes the nitrogen fixation and photosynthesis processes by which nitrogen and carbon dioxide are removed from the atmosphere and used as energy sources.|
|What Are the Properties of Water? - Unique Properties that Support Life on Earth||Explains how water's high specific heat capacity, density, solvency and other properties make life possible.|
|Water Resource Issues: Activities Affecting the Water Supply||Summarizes the adverse affects of removing too much surface and groundwater, such as sinkholes and the salinization of soil.|
|Aquifer Depletion and Overdrawing of Surface Waters: Effects on Water Resources||Provides examples of the environmental impacts of overdrawing from such resources as the Ogallala Aquifer and the Colorado River.|
|Water Conservation: How Water Management Can Lead to Sustainable Use||Explains the differences between consumptive and nonconsumptive water use and describes the practices of drip irrigation and wastewater recycling.|
|Water Storage: The Pros and Cons of Dams & Reservoirs||Shows how dikes, levees, dams and reservoirs prevent floods and generate power but also disrupt the environment.|
|Water Pollution: Definition, Types, and Sources||Describes the differences between point source and nonpoint source pollution as well as surface and groundwater pollution.|
|Water Treatment: Improving Water Quality||Discusses the use of settling, sterilization and filtration processes to improve water quality.|
|The Clean Water Act & Safe Drinking Water Act: Legislation for Clean Water||Outlines the Environmental Protection Agency's role in creating laws to regulate pollution and ensure contaminant-free drinking water.|
1. Cycles of Matter: The Nitrogen Cycle and the Carbon Cycle
Matter is constantly cycled between living and nonliving parts of the environment. Processes like photosynthesis and nitrogen fixation allow the carbon and nitrogen cycles to regenerate needed substances by recycling Earth's atoms.
2. What Are the Properties of Water? - Unique Properties that Support Life on Earth
In this video lesson you will learn about water and its unique properties. You will also develop an understanding of how these properties make life as we know it possible.
3. Water Resource Issues: Activities Affecting the Water Supply
This video lesson describes water resources issues such as aquifer depletion, overdrawing surface waters and salinization of irrigated soil. You will also learn about the impacts of activities affecting water resources.
4. Aquifer Depletion and Overdrawing of Surface Waters: Effects on Water Resources
This video lesson describes the effects of overuse on two major water resources in the U.S.: the depletion of the Ogallala Aquifer and the overdrawing of the Colorado River.
5. Water Conservation: How Water Management Can Lead to Sustainable Use
In this video lesson you will learn about the importance of water conservation. You will also learn about the two ways freshwater is used, and how proper water use can lead to sustainability in agriculture, homes, and manufacturing.
6. Water Storage: The Pros and Cons of Dams & Reservoirs
In this lesson, you will contrast the benefits and drawback of water storage. You will learn about how and why water is stored and how this affects the surrounding ecosystems and human communities.
7. Water Pollution: Definition, Types, and Sources
In this lesson, you will learn about the different types and sources of water pollution. You will gain an understanding of both surface water and groundwater pollution and the similarities and differences between them.
8. Water Treatment: Improving Water Quality
In this lesson, you will learn how water is purified for drinking, and how wastewater is treated before being put back into the environment. You will also learn about water purification issues in developing countries.
9. The Clean Water Act & Safe Drinking Water Act: Legislation for Clean Water
In this lesson, you will learn about the Clean Water Act of 1972 and the Safe Drinking Water Act of 1974. You'll discover how both laws help keep our waters free of pollution and safe for everyday use.
