Water Operator Certification Study Guide: A Guide to Preparing for Water Treatment and Distribution Operator Certification Exams 6th Edition

Do not get this study guide. While the questions are valid, I have so far found over 14 errors in the answers, i.e. clear calculation errors in the math answer key and incorrectly identified answers for simple questions. It looks like this version was never proof-read and if you rely only on the answers to the questions in this book, you will end up getting more questions wrong on your operator exam. Instead, get, read, and study the Water Distribution Operator Training Handbook (and similar one for water treatment) as that provides correct information as opposed to incorrect answers without the proper context. Finally, I even went to the references mentioned in some of the incorrect answers and even those references validate that this Water Operator Certification Study Guide selected an incorrect answer.If you want to pass your certification exam, avoid this "guide" like the plague!

Excellent study guide. I wouldn't have passed State Boards without this book. I would say 95% of the questions on the State test were in this book. It is well written, and easy to use for reference and study. Must have for preparing for exams across The Waterworks field of studies.

There's no training materials here other than test questions. Not bad, but is really a companion piece.

great all around book full of info for all grades 1-4, updated material easy to read print is good size,and with answers and explanation...

Absolute waste of money!!Nothing worth while, all questions are not even related on the actual examination..I've taken the test 4 times, and thexquestions are quite different.

I am going to need to study a lot more.

This is a must for passing the ABC exams.

Didn't help much for T4 test prep. :-(

Amazing and fast shipping
