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.
There are additional video libraries for drinking water operators and personnel associated with drinking water supplies in the State of Michigan. Practice examinations and study guide materials can be found under each general tab for all four license types: Complete Treatment (F levels 1-4), Limited Treatment (D levels 1-4), Distribution (S levels 1-4), and Noncommunity (F, D, and S Level 5).
