Doug Stendahl, B.Sc., M.Sc.
Instructor Attributes/ Strengths: Knowledgeable, Thorough, Enthusiastic, Helpful, Interesting, Prepared
Doug Stendahl has a Bachelor of Science from McGill University in Montreal and Masters of Science from University of Guelph. After initially getting his feet wet back in 1970 as a Laboratory Technician, Doug has lead a very distinguished career serving the water and wastewater sector. Subsequent to earning his degrees, Doug has accumulated very valuable “hands-on” experience. As a result of this impressive combination of academic and hands-on expertise, he has become a highly sought out consultant and teacher.
Over nearly 40 years plus and counting, he has applied his talents to environmental studies and water resource management, notably water supply and wastewater collection operation and maintenance, compliance monitoring, regulatory report preparation, water treatment optimization and contaminated site assessment and operator training, where his knowledge, presentation abilities and obvious passion for teaching other operators makes him a very effective facilitator.
Since 2005, Doug has been one of our longest serving, most requested instructors and has delivered water treatment or regulatory training for us across Canada to an impressive volume of operators. On special assignment, he was called upon to deliver specialized training to many of Ontario’s “grandfathered” operators. These operators had originally been grandfathered as new certification systems were initiated however, subsequent to later regulatory changes, they were then required to write and pass certification exams in order to keep their licenses and essentially, their jobs. This process was extremely stressful and challenging for many participants however Doug’s personal attributes allowed him to be both well received and extremely effective.
This 8-hour course has been developed recognizing the increasing acceptance of the use of membranes for drinking-water treatment. Being popular in the industry for less than 10 years, many practitioners, not directly involved with membrane treatment systems, will find this course interesting and informative. A good introduction for those considering membrane treatment in the future.
