Water Pollution

Next to the discovery of antibiotics, the advent of modern water treatment has had the biggest impact on human life expectancy. Water is an absolute requirement for all known life forms. Although there is a vast amount of water on the Earth, the majority of it is in the ocean. Additionally, the water supply on Earth is finite. All of the water we use is the same water that has been cycled through the Earth for millenia. This makes the problem of water withdrawal, consumption, and degradation a haunting one.


Water Pollution Lecture Powerpoint

Purpose: The first part of this lecture delves into the importance of water, its role in climate, and its distribution around Earth. The tragedy of the Aral sea in the former Soviet Union is used as an example of how water can be misused and eventually completely consumed. Special attention in this lectureis given to groundwater, which is the largest sources of freshwater in many regions of the world. Students will learn about infiltration, the source of groundwater, and contrast with the recharge zone of aquifers.

During the second part of the lecture, students are shown examples of different types of pollutants, ranging from inorganic salts and acids to organics such as sewage. Data from fish in Lake Michigan, as well as water testing results from tapwater in Illinois is used as examples of how pollutants find their way back into our diet. Finally, oil pollution in the ocean is highlighted, with the Exxon Valdez and Deepwater Horizon spills serving as examples of what can go wrong. A student notes outline is also available for this lecture.

Essential Concepts: Water pollution, hydrologic cycle, water cycle, evaporation, condensation, water budget, water resources, water supply, groundwater, freshwater, saltwater, icebergs, ice caps, glaciers, infiltration, water table, runoff, aquifer, recharge zone, wetlands, water consumption, water degradation, dams, dam construction, water conservation, point sources, nonpoint sources, pcbs, biomagnification, bioaccumulation, sediment, water quality, impaired waters, tap water, bottled water, spring water, water filtration, ozonation, reverse osmosis, distillation, heap leaching, mining, Pacific trash vortex, oil spills, oil tankers, Exxon Valdez, Deepwater Horizon, Oil Pollution Act, dissolved oxygen, biological oxygen demand, eutrophication, Clean Water Act.


Water Pollution Notes Outline

Purpose: Taking efficient notes can be a big challenge for many students, especially when working from a Powerpoint lecture. This outline gives students a means to take notes that guides them toward important concepts and avoids the pitfalls of writing word-for-word or simply not taking notes at all. The outline is written as a series of questions, fill-in-the-blanks, or diagrams. This outline is based on the Powerpoint lecture written specifically for this unit.

Essential Concepts: Water pollution, hydrologic cycle, water cycle, evaporation, condensation, water budget, water resources, water supply, groundwater, freshwater, saltwater, icebergs, ice caps, glaciers, infiltration, water table, runoff, aquifer, recharge zone, wetlands, water consumption, water degradation, dams, dam construction, water conservation, point sources, nonpoint sources, pcbs, biomagnification, bioaccumulation, sediment, water quality, impaired waters, tap water, bottled water, spring water, water filtration, ozonation, reverse osmosis, distillation, heap leaching, mining, pacific trash vortex, oil spills, oil tankers, Exxon Valdez, Deepwater Horizon, Oil Pollution Act, dissolved oxygen, biological oxygen demand, eutrophication, Clean Water Act.


Tapped Documentary

Purpose: The documentary "Tapped", released in 2009, presents a compelling case against the use of bottled water. Special attention is paid to Nestle, which owns many of the most popular bottled water brands in the United States, including Poland Springs and Ice Mountain. The impacts of the water withdrawal on the individual communities is explained, as well as the relative lack of FDA oversight of the water itself, especially compared to municipal tap water requirements. A second argument against the use of bottled water is the presence of Bisphenol A (BPA) in the plastic itself.

Essential Concepts: Water quality, water consumption, bottled water, water treatment, groundwater, BPA, endocrine hormone disruptors, Pacific trash vortex.


Up The Yangtze (Movie)

Purpose: The Yangtze river is the largest in China, and supplies freshwater to hundres of millions. When China began constructing the Three Gorges Dam, it was altering the flow and course of this river, creating a huge reservoir that forced the displacement of a million people. This documentary explores the importance of the river to rural China and documents the struggle of several families as they attempt to relocate from their small, rural farm, to an urban apartment.

Essential Concepts: Hydroelectricity, dams, fresh water, Three Gorges Dam, China, rivers.


Modern Marvels: Oil Tankers

Purpose: The worldwide oil market as we know it would not exist if not for oil tankers and supertankers. They continue to be the most efficient means of transporting oil long distances, particularly overseas. This episode of Modern Marvels explores the construction and design of oil tankers, briefly discussing some of the oil spills that have occured, and the resulting passage of the Oil Pollution Act of 1990.

Essential Concepts: Oil tankers, Exxon Valdez, oil spills, petroleum.


Dead Ahead - The Exxon Valdez Disaster (Movie)

Purpose: Until the Deepwater Horizon oil spill of 2010, the Exxon Valdez was the worst oil spill to occur in the United States. Although a great deal of oil was spilled from the tanker, much of its severity resulted from the disorganized cleanup effort that resulted. Prince William Sound, the area of Alaska affected by this spill, has yet to fully recover over 20 years later. This HBO movie is a re-enactment based on the actual events of the wreck, spillage, and eventual cleanup effort of the Exxon Valdez.

Essential Concepts: Oil pollution, oil tankers, oil spills, Exxon Valdez, oil cleanup


Water Pollution Study Guide

Purpose: Once the instruction for the unit is completed, students can complete this study guide to aid in their preparation for a written test. The study guide is divided into two sections: vocabulary and short answer questions. The vocabulary is taken directly form the lecture, sequentially. The short answer questions are meant to model the type they may see on the exam. This study guide is sequentually based on the Powerpoint lecture from this unit.

Essential Concepts: Water pollution, hydrologic cycle, water cycle, evaporation, condensation, water budget, water resources, water supply, groundwater, freshwater, saltwater, icebergs, ice caps, glaciers, infiltration, water table, runoff, aquifer, recharge zone, wetlands, water consumption, water degradation, dams, dam construction, water conservation, point sources, nonpoint sources, pcbs, biomagnification, bioaccumulation, sediment, water quality, impaired waters, tap water, bottled water, spring water, water filtration, ozonation, reverse osmosis, distillation, heap leaching, mining, pacific trash vortex, oil spills, oil tankers, Exxon Valdez, Deepwater Horizon, Oil Pollution Act, dissolved oxygen, biological oxygen demand, eutrophication, Clean Water Act.
