This site talks about related problems to groundwater contamination in Bangladesh and the challenges that face the people there.

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...

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.

This US Geological Survey site briefly discusses the basics of why pesticides are increasingly found in our ground water. Click Home to access the site in Spanish.

Learn about the public's drinking water, the oversight agencies that govern it, and what needs to be done in an emergency if it becomes contaminated.

After creating a model, students will investigate factors that affect water runoff both positively and negatively, and the impact this has on the quality of groundwater.

Critical source of freshwater and most abundant, yet also the most polluted is groundwater. Discover how scientists work to purify this important resource to make it useable.

Provides information on what to do after a flood to protect well water from contamination, the testing of private well water, and protecting private well water.

Young scholars 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...

This site defines and describes causes of ocean pollution. Easily navigated links to education, research, and current issues on pollution.

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...

This site, from an archived Smithsonian exhibit, describes and illustrates the effects of toxic materials on wildlife in bodies of water.

Excellent site covers all types of water pollution. Hundreds of links including books, articles, organizations, specific topics.

Table outlines the EPA's standards for safe drinking water, defining levels of contaminants and listing possible sources of these contaminants.

This site is provided for by Reach Out Michigan! Use the site to learn if our eyes and taste buds can detect contaminated drinking water by doing a simple experiment.

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...
