There are four study map tables, one for water treatment, wastewater treatment, water distribution, and wastewater collection. The Study maps are to assist the student to quickly find information associated with the competencies required for Level One, Two, Three, and Four examinations. Remember that the competencies developed through Level I and II are still required as you progress through to Levels III and IV. These guides are presented in an Adobe® pdfs® PDF file format.
A "How to use the study maps" should be your first download. This will provide you with an explanation of the structure and use of each of the tables.
