Maryland's Certification Guide and Examination Handbook

The Certification Guide and Exam Handbook are designed to help Maryland's environmental professionals prepare for certification to operate water and wastewater systems. 

Maryland state law requires certification of operators responsible for treatment, storage, and distribution of drinking water and collection, treatment, and discharge of wastewater. A rigorous certification process ensures that qualified personnel are operating Maryland's water and wastewater facilities.

The Certification Guide outlines the state certification requirements, as well as the certification renewal requirements. The Guide provides a step-by-step overview of the certification process.

The Examination Handbook describes in detail the examination process and how to prepare most effectively for the examination. It identifies the topics that are tested on each exam and offers helpful test-taking strategies.

These books were produced with funding and in partnership between the Maryland Center for Environmental Training (MCET) Water and Waste Operators Association of Maryland, Delaware, and the District of Columbia, and the Maryland Board of Waterworks and Waste Systems Operators.
