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...

"Stay curious. And you only have one reputation. Guard it with your life."
Hiring for judgment, not just rehearsed confidenceIndustrial water treatment is full of decisions made with incomplete data—on sites, with customers, and inside the business. JD Roth (Managing Director and Co-owner of Guardian Chemicals) builds his hiring around that reality. His aim is straightforward: protect the team and the culture by selecting people who can think, collaborate, and lead under pressure.
JD frames the organization as a group of people choosing to work toward a common goal: building a better future for communities, the environment, and staff. That priority shows how Guardian hires, who they keep, and what becomes a deal-breaker. If a candidate is misaligned with core values, JD is clear: performance elsewhere won’t override that mismatch.
The “Hiring Olympics” structure
For a high-bandwidth, project-based role (their Graduate Business Analyst program), Guardian needed a way to evaluate many strong candidates without consuming 40–50 hours of team time. The result is a four-hour, multi-station day that includes:
- Core values interviews (two-person format)
- Competency interviews (horsepower and capability)
- An individual case study (primarily math/business-oriented)
- A collaborative case study (decision-making and team dynamics)
The collaborative case study is the centerpiece. Candidates work with peers who are also competitors for limited roles, using real cases built around business decisions—often with imperfect or incomplete information—so the team can observe how candidates break down problems, delegate, support others, and present recommendations.
How decisions get made afterward
After candidates leave, the interview team convenes for a group decision. JD starts by looking for any “vetoes,” especially around core values to fit (he references an EOS-style standard of meeting 5 out of 6 core values most of the time). From there, the team compares notes across competency, core values, and observed collaboration behaviors.
Stay engaged, keep learning, and continue scaling up your knowledge!
