Dear Mr. and Mrs. Wahlberg,

I hope this message finds you well. I wanted to take a moment to express my gratitude for your excellent teaching. I attended your in-person class in April in San Bernardino, California, and I took my Grade 3 exam yesterday — and I passed!

Your teaching methods significantly helped me during the exam. With all your experience in this field, it’s clear that you have mastered math problems like no one else. Thank you for sharing your expertise with us. Instead of letting math intimidate us, your approach helped us understand how to work with units and use them in our favor.

Everything you mentioned in class proved invaluable during the exam. For example, your advice was crucial, along with many other strategies. I also encountered a few challenging questions, but thanks to your technique of process of elimination, I was able to navigate through them successfully.

Thank you once again, Mr. Wahlberg, for all your guidance. I look forward to seeing you again for the Grade 5 journey. You and Patti make a great team!

Best regards,  
Santiago Cortes Manzo

I felt like there was no chance I could pass the Grade 3 exam, even more so after I took it the first time. But, after attending the in-person classes, studying the video series, and reviewing the companion book, the outcome was very different.
This time around I felt like I was going to pass the test before I was ¾ of the way done. I did NOT need the equivalent and formula sheets at all (if anything they are more confusing now than ever), I got at least 9 out 10 math problems correct. I also have a much better understanding of wastewater beyond my treatment plant. The only complaints I have are that the State wastewater board doesn’t tell you what your percentage is above 70% when you do pass (I want to see how well I did!), and how much time I wasted learning and studying for the exam and wastewater in general the wrong way.
I am championing the solution bridge as I train the inmate OIT’s at my plant in which I have been using your material to clear up the confusion and misinformation in the Sac State water and wastewater treatment books. Thank you for giving operators a clear path to success and showing us, we can learn and do our best if we know what to do! – David Knopfer WASPO
Grade III Operator, Cal Fire

Because of your help, I felt that the wastewater grades 1,2,3, and 5 (I skipped the 4) exams were almost easy. I passed them all on the first try. The math method you teach is incredible. I also I passed my Water Treatment grade 3 exam last week and I didn’t even have to look at the formula sheet to do the math. Your method really works. You guys have an amazing program going on and I really appreciate all your hard work. – Corwin Mossman, Water Treatment Plant Operator II, Lake Arrowhead CSD

I want to thank you (Eric) and Patti for the work that you two do. Your program is truly a benefit to wastewater operators. I never used the solution bridge before, but I knew about it and was a little skeptical. After taking your class and putting in A LOT of practice time, I got it. Your class really made the test a whole lot easier and less intimidating. Thank you again! I won’t ever take a test again without the solution bridge! – Joseph Velasquez, Journeyman Maintenance & Facilities Worker for the City of Buellton

I have passed my grade 3 exam! Woot woot! I just want to thank both you and Eric (The Wahlbergs) and WWTT for helping me achieve this goal. Specifically, I’d like to thank Eric in his approach to teaching wastewater math, principles and concepts. Not only is the examination material covered really well, but being that there is still so much to learn about wastewater, I really appreciate the thoroughness of how each topic is broken down and explained. – Kevin Avalos, Grade III Operator, Dublin San Ramon Services District

Thank you for such a wonderful week of growth and development. You and Eric have provided me with a wealth of knowledge and the tools I need not only to ace the upcoming grade III exam, but to help me gain a clearer understanding (hopefully “crystal” in time!) of the wastewater world and all of its components.

From voicemail message: “This is Marco, and I didn’t pass my April exam, but I just passed my October exam. What happened was I had went over all my notes, even comments Eric had made in my Grade II Handout, and I studied I studied I studied, like my eyes were bleeding, and I ended up passing. I just wanted to tell you guys thank you, keep doing what you’re doing, it really works. The aha moment popped up in my head, and tell Eric I said, ‘Wastewater math is AWESOME!’ I love you guys. Thank you thank you thank you so much for your dedication, and for believing in me even when I didn’t.”

I failed the Grade II after taking a Grade II class with another trainer and then I tried an online class, but I still didn’t pass. My boss said if I didn’t pass the next one, I’d find myself in the soup line. Fellow operators recommended WWTT, so I signed up for the Grade II and then I put my nose to the grindstone. Eric teaches with a passion and excitement and keeps students up front and paying attention. That’s what makes all the difference, and makes this training stand out from other trainers. When I took the exam that third time, the answers just came flying out of my pencil. I felt so confident when I walked out, because I knew I had aced it.

Wastewater Technology Trainers is a must for anyone who is an operator or looking to get into the field. Eric does a great job of breaking down the different processes and his way of teaching math is a great help. I recommend his class to anyone with or without experience. They have helped me pass exams and make themselves available when you have questions. Thanks guys for your hard work.

The system that you’ve developed for teaching Operators chemical dosing problems is pure genius. This is truly a fool proof method that every Operator has the capacity to learn and use in and out of the classroom. What makes this a truly effective system is visualization of the data, minimization of conversion errors and continuity of using units and the solution bridge to solve the problem.

Thank you for your contribution to this industry, you are truly at the top of your field, especially in your ability to understand how Operators think and present concepts in a way that allows them to get it.
