AWWA's most popular operator training aid, this study guide is specially designed to give water operators and students practice in answering questions that are similar in format and content to the questions that appear on state certification exams. Sample questions and answers for both water treatment and distribution systems are included.

This study guide was developed by AWWA in cooperation with the Association of Boards of Certification (ABC), which certifies water and wastewater operators in most states. ABC certification is not only a way to protect public health and the environment, but also provides numerous career benefits to both employees and employers.

If you were previously familiar with AWWA's Water Operator Certification Study Guide, Sixth Edition this replaces that book, with all-new questions and answers.
