Dale Andreatta along with Fred Barrett is the inventor of the Water Pasteurization Indicator (WAPI), a simple thermometer that indicates when water has reached pasteurization temperature and is safe to drink.
Dale writes:
- "I am educated in mechanical engineering, getting BS and MS degrees from The Ohio State University in 1983 and 1984. After working for SEA, Ltd., an engineering consulting company, I went to Berkeley for a Ph.D. completing that in 1995. One of my minor areas was heat transfer, which is highly relevant in solar cooking and a number of other areas. While in California I hooked up with Solar Cookers International, and finished the design of the original WAPI. I also worked on several low-cost methods of water pasterurization. After graduating I moved back to Columbus Ohio and went back to work for SEA, continuing to work on water pasteurization as my time permitted. Along with others, I have authored several papers for the American Solar Energy Society about solar water pasteurization methods.
- Currently I am heavily involved with efforts to design clean and efficient cooking methods for the developing world using biofuels. All of this work is encouraged by my company as time allows, and they provide me with a small budget and laboratory space."

- January 2009: Dr. Dale Andreatta speaking on water pasteurization at the 2009 ETHOS conference - Dale describes the development of the WAPI, a simple device for determining whether water has been heated to a temperature that makes it safe to drink. He also discusses flow-through pasteurization devices and strategies to pasteurize water with the waste heat from a wood-burning cookstove.
