helped me pass

Awesome!

Bought the book to help our waste water plant operator pass his test.

It did not help me pass the IL EPA waste water exam

After having just took the test was not impressed on the questions covered on the level 3 for Oregon. Pretty much a waste of time. Maybe 4 questions showed up on test. Was bummed but I past due to experience in the field. Math would be useful. Questions about pumping as well.

wasn't what I expected but it has study information

This is a very thorough set of practice questions - all multiple choice - with a separate section giving answers and sources of reference for each group of questions. The book is 273 pages long, spiral bound, and includes 4 grade-level sections of questions, a section on pumping questions, a section of operator math with solutions, and in the appendices are a summary of wastewater treatment equations and a host of wastewater flowchart diagrams. An extremely thorough self study guide to accompany any number of texts on the subject. The author also includes a fairly extensive reference list that a user could access to learn the material from in the first place.
