Talks about history of public health and water systems and what kind of projects are being used to improve them.

Student teams locate a contaminant spill in a hypothetical site by measuring the pH of soil samples. Then they predict the direction of groundwater flow using mathematical modeling. They also use the engineering design process to come up...

Students are introduced to the fundamentals of environmental engineering as well as the global air, land and water quality concerns facing today's environmental engineers. After a lesson and activity to introduce environmental...

Hamilton Harbour is home to the largest and most contaminated site within the Canadian side of the Great Lakes - Randle Reef. The site contains approximately 695,000 cubic meters of sediment contaminated with polycyclic aromatic...

Set in the context of ground water contamination in Bangladesh, this stoichiometry and analytical chemistry activity examines the issues around identifying wells contaminated with arsenic.

Discusses many options of water treatment, the contaminants that the treatments are focused on, how the treatment works, and common treatment systems.

Illustrated tutorial explains nonpoint source pollution and its role in the health of the environment. Students learn about different sources of pollution and how these pollutants contaminate the land, air, and water. Click on the links...

Looks at types and sources of land pollution, the impact, soil contamination, what individuals can do to combat land pollution, and tips for recycling.

Find chronologies from three different sources of Love Canal and its chemical contamination. Read about how the investigation of this environmental disaster progressed over the years.

The World Health Organization answers questions relating to dioxins in our environment. Learn what dioxins are, how they effect our health and what is being done about possible contamination of the food supply.

In this science simulation, students test milk samples to check for bacterial contamination.

In this science simulation, students learn how use gram staining to test for bacterial contamination in yogurt.

In this science simulation, students learn how to use a microscope as they investigate bacterial contamination in a sample of yogurt.

Provides information about water quality, contamination in private wells, well construction and pump installation for private wells, a list of laboratories certified to test for bacteria and other contaminants, recommendations for...

Tells the story of Love Canal, NY and the contamination that was happening there and what has been done about it recently.

This site discusses how the state of California is protecting their rivers and streams from contamination

This illustrated history surveys the infamous Love Canal chemical contamination environmental disaster of the 1970s.

Excellent information provided by the U.S. Geological Survey.

Students measure the effectiveness of water filters in purifying contaminated water. They prepare test water by creating different concentrations of bleach (chlorine-contaminated) water. After passing the contaminated water through...

Students are presented with examples of the types of problems that environmental engineers solve, specifically focusing on water quality issues. Topics include the importance of clean water, the scarcity of fresh water, tap water...

Drinking water comes from many different sources, including surface water and groundwater. Environmental engineers analyze the physical properties of groundwater to predict how and where surface contaminants will travel. In this lesson,...

Water pollution is the contamination of water resources by harmful wastes or toxins. This type of pollution can be dangerous to animals and plant populations in and around lakes, rivers, polluted groundwater areas or oceans, and can pose...

Contamination in drinking water sources or watersheds can negatively affect the organisms that come in contact with it. The affects can be severe - causing illness or, in some cases, even death. It is important for people to understand...
