There are a number of ways to prepare for a wastewater certification exam, including reviewing practice questions from a sample wastewater treatment exam from the Association of Boards of Certification, enrolling in a preparatory course with an academic institution such as the American Water College or reviewing the study materials specific to the Department for Environmental Protection for your state. Test preparation materials include collection formulas and conversion sheets, math reviews and wastewater collection system operator certification manual reviews.
To prepare for the wastewater certification exam, the Association of Boards of Certification recommends that you follow the sample exam questions to familiarize yourself with the format of the certification exam. Many states, such as Utah, use standardized exams produced by the ABC. The American Water College offers students online courses guided by a student support team in a range of subject areas, including wastewater exam preparation courses for grades 1 through 4. Enrolled students gain access to handouts, practice tests, video lectures and online flashcards.
Individual states such as Utah, Kentucky and California also provide online wastewater certification exam study materials. The Utah Department of Environmental Quality offers exam preparation information and suggestions, the Kentucky Energy and Environment Cabinet Department for Environmental Protection offers study materials and test strategies, and the California Water Environment Association publishes study guides for wastewater treatment plant operators, grades 1 through 5.
