George T. Bowman, Retired
Former Science Management Supervisor
University of Wisconsin-State Laboratory of Hygiene
Former Wisconsin DNR Contract Auditor

George was employed by the University of Wisconsin- State Laboratory of Hygiene since 1973. He served many years as a Science Management Supervisor in the Environmental Health Division. For more than 30 years George has been actively involved in teaching laboratory training classes to commercial and municipal laboratories throughout Wisconsin. He has also been a guest lecturer for a graduate level water analysis class at the University of Wisconsin-Madison. George received the Wisconsin Wastewater Operator’s Association’s (WWOA) prestigious Koby Crabtree award for training in 2010, the Bernauer Award in 1998, and the Service Award in 2017, making George one of only three individuals to have received all three of the WWOA’s highest honor awards..

Since 1986 he has served as a technical expert on the Biochemical Oxygen Demand (BOD) Task Group for Standard Methods for the Examination of Water and Wastewater. Following retirement in 2009, George worked 6 1⁄2 years as a contract lab auditor forf the DNR’s Lab Certification Program. George’s most challenging project was to keep Rick on his toes and give him grief as much as possible.

Richard G. Mealy, Retired
Former Program Chemist, Laboratory Certification and Registration Program
Wisconsin Department of Natural Resources

Rick was involved with the Wisconsin DNR since 1992, and retired in January 2018 after serving as the program chemist for the Laboratory Certification & Registration Program for 15 years. He was honored with the Wisconsin Wastewater Operator’s Association’s (WWOA) prestigious Koby Crabtree award for training in 2008. Since 2016, Rick has also served on the WWPA Board of Directors.

Over the past 20 years, Rick has been involved in establishing and conducting training programs for laboratories performing drinking water and wastewater compliance testing. He has also been actively involved in training public water supply operators in the areas of water disinfection and chemical addition monitoring. He is also an occasional guest lecturer for a graduate level water analysis class at the University of Wisconsin-Madison. He and George, and then Rick solo have been conducting half day workshops as part of the Wisconsin Wastewater Operator’s Association

Prior to joining the DNR, Rick spent eight years managing quality assurance programs for several commercial laboratories. When not responding to QA/QC crises, he published several articles and made a number of presentations related to the need for technical training for laboratory chemists.

There is a MWOA Process Control/Laboratory Training Committee that plans training once a year and is a great resource for questions regarding testing for registered labs and also testing for process control for running your wastewater plant efficiently.
