Upcoming Change for Reporting Sanitary Sewer Overflows or Bypasses in Mississippi-effective December 21, 2025. Click here for more information.
In 2026, MDEQ’s wastewater operator certification program will be transitioning from our existing wastewater examinations to the standardized wastewater examinations developed by our testing partner, WPI. These new exams are developed in conjunction with a volunteer team of wastewater professionals from across America who act as subject matter experts for test question creation, and these questions are compared against a Need-to-Know-Criteria for each level of examination. Job analyses and psychometric analyses are conducted as part of the exam development process to ensure that these exams are relevant to the real work operators are doing on the job, and that the exams are fair and unbiased. WPI’s standardized wastewater exams are used in the wastewater certification programs of many states and territories, as well as internationally. We believe that these new examinations will serve as more accurate evaluations of potential operators’ understanding of the wastewater field as it exists today, as well as being more closely relevant to their duties on the job. Information on Need-to-Know-Criteria, as well as on exam development, study resources and more can be found at WPI’s website at this link.
