In 2007, he was recognized as the Educational Professional of the Year by theMichigan Water Environment Association. He is a registered professional engineer in Michigan.Dr. Davis is the author of a student and professional edition of Water and Wastewater Engineering and Co-author of Principles of Environmental Engineering with Dr. Susan Masten. In 2003, Dr. Davis retired from Michigan State University.



David A. Cornwell, Ph.D., P.E., BCEE, is a registered professional engineer in 19 states and is the founder and president of the consulting firm Environmental Engineering & Technology, Inc. (EE&T) headquartered in Newport News, VA. He attended the University of Florida in Gainesville, FL, where he received his Ph.D. in civil/environmental engineering and has remained a loyal Gator fan ever since, serving as a Bull Gator and on the Presidents Council. He was an associate professor in the Civil Environmental Engineering Department at Michigan State University prior to entering the consulting field. Many of Dr. Cornwells students now are active members of the water profession.During his career as a consultant, Dr. Cornwell has provided process, design, and operational troubleshooting services to water utilities around the world. He has lectured and written on many aspects of water treatment, including over 50 peer-reviewed technical articles and reports. Much of his work has included the development of new and optimized water treatment processes. He has won three JAWWA Division best paper awards and the overall JAWWA publication award. Dr. Cornwell has an extensive record of service to the water profession. He has been an active member of American Water Works Association (AWWA) since the early 1970s and has served on numerous committees in that organization. He has chaired the Research Division and the Technical and Education Council, and served on the board of directors and executive committee of AWWA.In 2005, Dr. Cornwell was the recipient of the A.P. Black Research Award given by AWWA to recognize excellence in water treatment research, recognizing his contributions to bridging the gap between research and application. Dr. Cornwell has been a principal investigator on over 20 Water Research Foundation research projects.
