Water System Operations (WSO) Water Treatment, Grade I

Covers everything you need to know to pass the first tests.

Suprise, this is a book

Great book. Lots of helpful things in it for studying for my certification exam.

It’s a good book for treatment lessons, but my god is it boring

Exactly what my husband needed for class

This book contains all of the information needed to pass the entry level State certification for Water Treatment Operators. It is written in non-engineering language that is suitable for operators. The Grade 2 and 3&4 books in this series add more advanced information needed for the higher level certification exams. At this price this is the best reference for operator certification study.

Two stars because it gives a lot of information. Many times throughout the book I found myself thinking that the information was far more in depth than should be necessary for a Grade 1 Operator. As it turns out, much of the information is also printed in the Grade 2 Water Treatment book, word for word. The chapter study questions answers often can't be found in the chapter. I (wrongly) assumed the exam would be more along the lines of the treatment process, but felt it was more geared towards a basic worker performing random tasks at a treatment plant. The videos the book refers to feel old and rush through the information. I passed my test, but feel that was due to my previous education and being able to figure it out. This book didn't inspire any confidence, before or during the exam.

I passed my test but no thanks to this book. It is full of misprints, like the optimal pH range for alum being listed differently at different spots in the book, and a lot of the questions at the end of the chapters aren't covered in the book (manganese greensand filters for example, but there are many more). My test had a lot of safety questions, which this book ignores. Chemical transport and storage, which this book barely touches. It also isn't very helpful for the math. It has like 50 pages on dimensional analysis, but not any example problems you will have on the test. Out of the 100 questions I had, I'd say like four were in this book. The book is just too vague and leaves out the details the test is going to ask you.
