Instructor Attributes/ Strengths: Experienced, Collaborative, Life-long Learner, Inspiring, Enthusiastic, Knowledgeable



Michael retired in 2016 after a long distinguished career with Toronto Water where he served as the Manager of the Toronto Water Laboratory, a group of municipal laboratories that provide analytical services meeting the diverse needs of Toronto Water.


Michael has had almost 32 years of laboratory experience, specializing in water treatment. He began in the public sector working for the former Metropolitan Toronto Department of Works. He worked his way up from the laboratory bench in various water treatment plants becoming a plant Chief Chemist. During this time a large part of his responsibility involved working with plant staff providing technical training for process analyses including both manual and on-line equipment. Quality Control of the finished product was another area he worked closely on with plant operations staff. Municipal amalgamation in 1998 would eventually lead to the formation of Toronto Water. Michael’s responsibilities changed to include the running of the drinking water distribution sampling program for Toronto Water. In 2006 he was promoted to his current position as Manager. His laboratories are responsible for the analysis of samples from a variety of sources including drinking water, wastewater, industrial wastes, landfills as well as lakes and streams.


Michael’s personal experiences in both the laboratory and in the plant make him uniquely qualified to deliver training to operators and water quality analysts. He continually attends conferences and seminars to remain current on drinking water treatment issues. He has presented at seminars and conferences on issues related to laboratories and drinking water regulations. One of his latest work-related initiatives was to closely examine lead levels in drinking water and upcoming changes to wastewater effluent regulations.




This 8-hour course is designed to help operators understand the importance of disinfection in water and wastewater. Disinfection of pathogens in wastewater and water continues to be essential to reduce risks of pathogen exposure and waterborne diseases of humans and animals.  Municipal raw sewage may contain viral, bacterial and protozoan pathogens.  Therefore, it is necessary that wastewater treatment processes be effective in removing or destroying these pathogens before the resulting effluents and residuals are returned to the environment.
