Preparing for your exam


 Ontario has adopted ABC standardized exams for:

  • Water Treatment and Water Distribution and Supply (Class 1 to 4)
  • Wastewater Treatment and Wastewater Collection (Class 1 to 4)

The water quality analyst, water distribution, limited subsystem and operator-in-training exams continue to use current Ontario exam content.

For more information, please see:
Ontario Drinking Water and Wastewater Certification Exams: Upcoming Changes

The following tables list appropriate study materials for each exam – for Drinking Water and Wastewater.

All ‘need-to-know’ documents are available at no cost and can be accessed via the links below. Study guides and manuals relevant to each exam are also listed, with information on how to order them. The study guides and manuals provide a broad overview to the subjects covered on exams.

The resources are to help operators prepare for exams. They are not intended to replace the appropriate training and experience an operator should have. These resources may not completely cover all exam subject areas.

To purchase study materials, please visit our Bookstore.
