Ch 9: Pollution of Freshwater Resources

About This Chapter

Watch online video lessons to learn about the pollution of freshwater resources. Each lesson is accompanied by a short multiple-choice quiz to help check your understanding of topics like the water cycle, aquifer depletion, water conservation and water treatment.

Pollution of Freshwater Resources - Chapter Summary and Learning Objectives

As you likely know, we cannot live long without water. Our body is made up mostly of water, so we have to replenish it with water on a regular basis. What you may not know is that there are many illnesses that can be caused by drinking unclean water. Additionally, there are some countries that don't have sources of clean drinking water. In the U.S., we are lucky because there are laws to protect us from unclean water conditions. As you will learn in this chapter, though, keeping water clean, even here in the U.S., can be tricky. This chapter will introduce you to topics that include:

  • The steps in the water cycle
  • Properties of water
  • Water resource problems
  • Water conservation efforts
  • Water pollution
  • Water treatment

VideoObjective
The Water Cycle: Precipitation, Condensation and Evaporation Study the steps and two major driving forces of the water cycle.
Cycles of Matter: The Nitrogen Cycle and the Carbon Cycle Learn how carbon and nitrogen cycle through the environment through biotic and abiotic components.
What Are the Properties of Water? - Unique Properties that Support Life on Earth Identify the unique properties of water and how it supports life on earth.
Water Resource Issues: Activities Affecting the Water Supply Discover some of the problems caused by aquifer depletion, overdrawing of surface waters and salinization of irrigated soil.
Aquifer Depletion and Overdrawing of Surface Waters: Affects on Water Resources Look at water resources problems with the specific examples of the Ogallala Aquifer and the Colorado River Basin.
Water Conservation: How Water Management Can Lead to Sustainable Use Define and give examples of conservation in agriculture, industry and the home.
Water Storage: The Pros and Cons of Damn & Reservoirs Contrast the benefits and drawbacks of dams and reservoirs.
Water Pollution: Definition, Types and Sources Study the two types of pollution sources.
Water Treatment: Improving Water Quality Examine how most drinking water is purified in U.S. and learn about primary, secondary and tertiary treatments.
The Clean Water Act & Safe Drinking Water Act: Legislation for Clean Water Compare the goals of two acts.

10 Lessons in Chapter 9: Pollution of Freshwater Resources
The Water Cycle: Precipitation, Condensation, and Evaporation

1. The Water Cycle: Precipitation, Condensation, and Evaporation

This lesson discusses the processes water takes as it moves around the Earth in the water cycle. You'll get an in-depth look at condensation, precipitation, and evaporation.

Cycles of Matter: The Nitrogen Cycle and the Carbon Cycle

2. 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.

What Are the Properties of Water? - Unique Properties that Support Life on Earth

3. 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.

Water Resource Issues: Activities Affecting the Water Supply

4. 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.

Aquifer Depletion and Overdrawing of Surface Waters: Effects on Water Resources

5. 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.

Water Conservation: How Water Management Can Lead to Sustainable Use

6. 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.

Water Storage: The Pros and Cons of Dams & Reservoirs

7. Water Storage: The Pros and Cons of Dams & Reservoirs
