A lot of the terminology used in wastewater treatment can be confusing, especially for those just beginning their career. Before nutrient removal was a concern, wastewater treatment aimed at the removal of solids and organics.

“I just received results from the Grade I exam, and I did in fact pass. Thank you so much for all your help. You provided me the foundation to study upon, and I knew I got 100% on the math. Despite being the ONLY person in the class to not understand it, I put in the time. Similarly to what I learned in The Military with the NAVY SEAL/S, failure is not an option. With that being said, I suppose that’s why I was so frustrated, not getting the methods. I will now use the same methods to study for my grade II and take that exam in April. Thank you again.”

“You and Eric are doing a great service to the wastewater industry with your classes. Eric’s method of teaching engages students, and the RR track method of teaching the math gets around memorization and lack of algebra skills. I can’t believe I’m already taking the Grade 5 exam. I started in this industry only 5 ½ years ago. For the Grades 2, 3, and 4 exams, Eric paved the way for my success. I had to study on my own, but the tools he gave me were invaluable to pass those exams.”
– James D. Anderson, General Manager, Malaga County Water District
