Water Operator Certification Exam Prep

I needed to review for an exam. Very helpful!!

Very in depth.

Great review book. Husband used it and passed his exam

Spot on. A must for studying water treatment

Very helpful

Quality of product was good

Looks like a good study guide for the test. It is 50/50 treatment and distribution questions/answers.

This is a very good study helper. You must still put in the time studying but this material guides the way. Glad to have this option for exam prep.

This was a real disappointment as the first 138 pages were obviously from a bible workbook. I'm not sure how this would happen but it was a combination of 2 books. The first half was bible study questions and the second half was the actual water exam practice questions. Will be sending it back.
