466 Stories, Math, and “Never Again” Moments: Inside AWT Technical Training with Dan Merritt (Part 2)
Scaling UP! H2O
AWT’s in‑person technical training is a keystone for developing competent water treaters. Yet classroom knowledge only matters when it survives the drive home and emerges later in the field. In this second conversation with —National Sales Manager at and head of AWT’s education committee—Trace Blackmore uncovers how stories, math, and memorable mistakes turn theory into intuition. Why training keeps evolving Dan explains that the rewrites courses every year. Instructors refine content, delivery and demonstrations, not for novelty’s sake, but because...

465 From Classroom to Cooling Towers: Teaching Water Treatment with Dan Merritt (Part 1)
Scaling UP! H2O
Industrial water training only works when the knowledge transfers. That means the material lands with the audience, survives the drive home, and shows up later in the field when decisions get made. , Sales Manager at , brings a rare perspective to that problem. He started as a teacher (chemistry, calculus, physics), entered industrial water treatment on February 5, 2002, and later became part of the AWT training team. This conversation follows the path from classroom instruction to boiler rooms and cooling towers, then uses that journey to examine what makes technical training...

464 Corrosion Coupons, Brand Building, and Having Fun at Trade Shows with Will Ritter
Scaling UP! H2O
"Don't be afraid to say I don’t know. - Will Ritter” Corrosion is expensive, relentless, and easy to underestimate—until a “lasagna battery” turns aluminum foil green and reminds you what electrochemistry can do in the real world. This conversation reframes corrosion coupons as what they actually are: a repeatable field test that can sharpen your decisions—if you treat the process with consistency. Respect the coupon, protect the data Trace breaks down why coupons became non-negotiable in his systems: they turn guesswork into usable...

463 Mapping the Future of Water Innovation with Paul O’Callaghan
Scaling UP! H2O
“If you say something over and over often and enough, it becomes true because perception is reality.” has built a career at the intersection of water science, wastewater realities, and the practical question every operator and executive eventually faces; what actually moves innovation from idea to adoption. As Founder and CEO of, Paul explains how his team helps decision-makers put capital to work more efficiently in water by reducing uncertainty and separating signal from noise. He describes patterns he’s watched repeat across water entrepreneurs, pilots, and...

462 From Lab Chemist to Field Mentor: Water, Culture, and Representation
Scaling UP! H2O
Industrial water work rewards people who can move between precision and practicality. brings both. She started as a lab chemist, then transitioned into field service with , where much of her work supports healthcare facilities and high-accountability programs. Lab habits that protect your tools and your data Katie describes the first surprise of field work: a central plant is “very dirty,” and the job demands good technique without chasing lab-level perfection. She shares a couple of simple practices that prevent expensive problems. Use proper lab wipes on...

461 Corrosion, Lead, and Algae: New Tools for Old Water Problems
Scaling UP! H2O
Corrosion rarely announces itself as a “big water problem.” It shows up as leaching at the tap, residual loss in the field, premature equipment replacement, and the slow, expensive erosion of decision-quality. (CEO) and (chemist/Chief Science Officer) of lay out a system-wide view of corrosion control—starting with what changed in Flint from a technical standpoint and moving into why many utilities still struggle to meet expectations when standards and risk assumptions shift. System-wide corrosion control starts with chemistry...

460 Building Boiler Talent: Fundamentals, Online Training, and Better Partnerships with Eric Johnson
Scaling UP! H2O
Boilers can feel intimidating the first time you step into a boiler room—the heat, the noise, the pressure gauge, and the weight of knowing that mistakes can be costly. Trace Blackmore opens with a reminder that boilers deserve respect, not fear—and that learning fundamentals is how you replace mystique with clarity. The talent gap behind the boiler room door , Founder and CEO of , explains why boiler expertise is becoming harder to replace. He points to the shrinking pipeline of boiler-trained technicians—historically strengthened by Navy steam...

459 From Wastewater to Resource: Water Reuse with Dr. Veronika Zhiteneva
Scaling UP! H2O
Industrial water professionals are increasingly pulled into conversations about scarcity, resilience, and “where the next gallon comes from.” , CEO and Co-founder of frames water reuse as an implementation challenge more than a technology gap—and explains where the practical starting points are when the scope feels overwhelming. Moving reuse forward when the technology already exists Waterloop Solutions was founded to accelerate implementation: clarifying end-use quality, identifying post-treatment needs on the back end of...

Industrial water training only works when the knowledge transfers. That means the material lands with the audience, survives the drive home, and shows up later in the field when decisions get made.
Dan Merritt, CWT, Sales Manager at CH2O, brings a rare perspective to that problem. He started as a teacher (chemistry, calculus, physics), entered industrial water treatment on February 5, 2002, and later became part of the AWT training team. This conversation follows the path from classroom instruction to boiler rooms and cooling towers, then uses that journey to examine what makes technical training “stick” for working professionals.
From educator to water treater, then back to educator
Dan shares how leaving graduate study, teaching high school and community college, and stepping into service work shaped his approach to explaining technical concepts. The throughline is simple: the instructor owns the clarity. When someone in the room does not understand, the response is not frustration. The response is translation.
Bridging the knowledge gap without dumbing it down
Trace and Dan describe a common failure mode in technical instruction: experts answering correctly, but not helpfully. They frame the goal as closing the gap between what the instructor knows and what the audience can realistically absorb in the moment, especially for attendees building competence over time.
Stories and demonstrations as tools for retention
The episode highlights why AWT trainers lean on stories and physical demonstrations, from an Archimedes fountain to static electricity experiments. Dan explains how the “light bulb moment” is the reward of teaching, and why trainers adapt when a method fails (including what humidity can do to a demo in a room full of people).
Keeping the CWT exam in proper context
The conversation also draws a firm boundary: training supports growth, but it does not replace the CWT experience requirement and recommendations. Dan and Trace emphasize accurate language around the credential and reinforce what the training can and cannot do.

Quotes
“It’s your job to explain the material in a way that we can understand it.”
“It’s our responsibility to take this information, to package it in a way so you, not me, you can understand it.”
“Math is the only known axiom that we have. And it kind of quiets the chaos.”
“And again, it’s not a test. Do not say that it’s a test. It is an exam.”
