The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has prerecorded course videos related to drinking water limited treatment systems. These videos are intended for drinking water operators and personnel associated with D-Class drinking water systems in the State of Michigan. These lessons will cover basic information in the subjects important to limited treatment systems.
Please note that these prerecorded courses do not qualify for continuing education credit.
Below is the link to the new Math Formula Sheet that will be included in every examination booklet. It is being provided to you as a study guide and resource. Please do not bring a copy of this to the examination. This sheet was created in conjunction with the Advisory Board of Examiners and the Subject Matter Experts in every examination category.
Practice examinations, answer keys, and practice examination math videos are intended for drinking water operators preparing for drinking water certification examinations. Practice examinations provide an outline of what an operator may expect to see on the certification examination. The answer keys provide step-by-step solutions to calculation-based practice questions. The practice-examination math videos show in detail how to perform and solve the calculation-based practice questions. Study guides are intended to give drinking water operators a list of subjects typically covered on various certification examinations. Study guides also contain a list of reference books that operators can utilize as additional studying materials.
The lessons below range from 10 minutes to 90 minutes depending on the topic. These videos are intended to give the drinking water operator a better understanding of the processes and regulations associated with limited treatment of community drinking water.
