- Acid-Rain Program
Check out the section entitled, The Acid Rain Program -- It's Working if you are interested in: Does EPA mandate how sulfur dioxide reductions must be achieved? ; Could some areas of the country experience an increase in pollution? ; How does EPA know that the reductions are really taking place? ; Does the allowance trading system really "sell" pollution? ; What happens if a utility emits more sulfur dioxide than it is allowed? ; What will controlling acid rain cost the consumer?

- EPA's Water Atlas
Includes an image gallery with maps of rivers and wetlands in the U.S., useful for both lecture display and for PowerPoint presentations. An image gallery with freshwater consumption and "water withdrawals" on a state-by-state basis. The threats to the health of U.S. waters, including pollutant discharge, agricultural run-off, urban run-off and wetland loss.

- Mysteries of Water
This article by Ken Jordan of the Pittsburgh Supercomputing Center addresses water. The results of calculations on small groups of water molecules are used to examine why liquid water is able to carry so much heat and the surface tension of liquid water. "If the heat capacity of water were half of its actual value, the temperature fluctuations in our environment would be more extreme, and this would have important implications for life itself."

- Water
By Martin Chaplin, South Bank University, UK, "Because of its clear importance, water is the most studied material on Earth. It comes as a surprise, therefore, to find that it is so poorly understood, not only by people in general, but also by scientists working with it everyday."
