One avoided re-sit
pays for the book
Sitting the EPA 608 exam again means paying the exam fee again. This $12 edition is built to help you pass the first time. Results vary.
For candidates preparing for Section 608
EPA 608 Explained: Digital Edition
$12
- Worked example: the exam page (How much does the EPA 608 exam cost?) puts the exam at roughly $85, so one avoided re-sit is worth more than seven of these $12 editions.
- Every regulatory fact cited to 40 CFR Part 82, with the exam structure from Appendix D.
- The leak-rate and recovery chapters plus practice questions with their citations.
The complete guide: every regulatory fact cited to 40 CFR Part 82, the exam structure from Appendix D, the leak-rate and recovery chapters, and the practice questions with their citations. Instant web access, printable to PDF, every future revision included.
