Series provides test preparation for water operator certification
The American Water Works Assn. (AWWA) launched new versions of its Water System Operations (WSO) series with updated editions of Water Treatment, Grade 1; Water Treatment, Grade 2; and Water Treatment, Grades 3 & 4. WSO: Water Distribution Grades 1 & 2 and Grades 3 & 4 will be available this fall.
The WSO series provides test preparation materials for water operator certification. Additionally, it is the only book series aligned with current Association of Boards of Certification (ABC) Need-to-Know criteria. ABC administers water operator certification testing for the majority of North America.
The series is designed to assist water operators in preparing for the certification exams by focusing on core test content, including regulations, specific treatment processes, water quality testing and treatment plant safety. Test questions, full-color graphics and illustrations, and links to additional instructional videos are included in each chapter to further assist students in their test preparation.
