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.

458 Hiring Olympics and High-Performance Culture with J.D. Roth
Scaling UP! H2O
"Stay curious. And you only have one reputation. Guard it with your life." Hiring for judgment, not just rehearsed confidence Industrial water treatment is full of decisions made with incomplete data—on sites, with customers, and inside the business.

456 The 12 Days of Scaling UP! H2O 2025
Scaling UP! H2O
A year-end recap is more than a highlight reel—it’s a practical reset. In this New Year episode, Trace Blackmore walks through 2025 using a “12 Days of the Scaling Up Nation” format, tying together performance, community growth, listener engagement, and the sponsor support that keeps the podcast and its companion tools available at no cost. Year-end by the numbers Trace explains how he used to track every stat closely—and how that shifted into an unhealthy measure of self-worth—so the team now uses numbers as feedback, not validation. He notes the...

455 Mentors, Mindset, and the CWT: Owning Your Water Career with Nella Fergusson
Scaling UP! H2O
“So one thing I never do is try to start giving remediation or advice before I truly have understood and diagnosed the problem.” Mentorship and certifications don’t replace experience—but they can accelerate it when paired with the right mindset and a disciplined approach to learning. (District Manager, Southern California, ), lays out what “growing up” in industrial water treatment actually looks like: repeated exposure to real problems, strong diagnostic habits, and a willingness to keep learning long after year one. Learning that keeps...

454 Water Recycling, Innovation, and Industry Wisdom with Dr. Kelle Zeiher
Scaling UP! H2O
Industrial cooling is one of the biggest levers industrial facilities can pull on water use—and it’s getting harder to ignore as data centers and other high-heat operations grow. Returning guest (Project Manager at ) breaks down what water reuse looks like when you move past slogans and into the realities of pretreatment, concentrate management, footprint, and cost. Cooling water reuse: the scale of the opportunity Dr. Zeiher reframes “drought” beyond rainfall, emphasizing aquifer recharge and the limits of focusing only on household restrictions. She...

453 Water Risk, Governance, and Community Engagement with Dr. Annette Davison
Scaling UP! H2O
Industrial water professionals sit at the intersection of risk, regulation, and community trust. In this episode, (“the water risk doctor”) joins Trace Blackmore to show how disciplined governance, clear supply chain thinking, and community engagement can turn fragmented water systems into coherent, defensible risk management frameworks. Water risk from source to customer Annette starts with a simple question most customers never ask: “Where’s your water coming from?” She walks through a conceptual supply chain from source to end point—collection, transfer, treatment,...

452 UV Innovation and Whole-Building Water Safety with Ron Blutrich
Scaling UP! H2O
Entamoeba histolytica nearly ended Ron Blutrich’s scientific career. Instead, it pushed him to rethink how we protect people in multi-family buildings, senior facilities, and dense urban centers from invisible microbiological risks in their drinking water. In this episode, he joins host Trace Blackmore to unpack what whole-building UV can (and can’t) do for Legionella, biofilm, and real-world water safety. When One Bad Cup of Water Redefines a Career In the middle of his PhD in molecular genetics, Ron drank from an under-sink reverse osmosis tap at an Airbnb and...

451 Building a Culture of Innovation and Customer Service with Frank Lecrone
Scaling UP! H2O
What happens when you build a company around one niche, listen obsessively to customers, and never stop improving? In this episode, host Trace Blackmore finally sits down for a full-length conversation with , Founder, President, and CEO of .

Legionella remains one of the most complex challenges for water professionals worldwide. How do we balance effective monitoring with realistic costs—and which strategies deliver true public health impact? In this episode, Trace Blackmore welcomes Dr. Vincenzo Romano Spica, Head Public Health University of Rome "Foro Italico to explore new insights from his comparative research on Legionella control.
Reframing Legionella Risk
Dr. Spica explains why public health data increasingly points to Legionella pneumophila—not all Legionella species—as the primary concern for human health. He shares how pan-European data modeling and peer-reviewed studies demonstrate that broad-spectrum monitoring may overburden systems without delivering proportional safety gains.
Cost-Benefit Models and Sustainability
Water professionals know that testing and compliance require resources. Dr. Spica discusses cost-benefit analysis frameworks that help decision-makers evaluate where investments deliver the greatest reduction in risk. He also highlights the sustainability implications of over-testing, from lab resources to environmental waste streams.
European Regulations and Legal Liability
The conversation also explores the European Drinking Water Directive 2020/2184, national approaches to Legionella, and how liability shifts when contamination is detected. Dr. Spica’s insights illuminate what building owners, operators, and regulators must weigh as they update management plans.
Conclusion
For engineers, operators, and technical managers, this episode provides a clear framework for thinking about Legionella beyond routine testing. It’s about focusing on the pathogen that truly drives disease outcomes, aligning regulatory strategy with science, and applying resources where they matter most.

Quotes
“Not all Legionella are equal—public health data shows us it’s Legionella pneumophila that drives the real risk.”
“Testing everything may look safer on paper, but in practice, it diverts resources from where they can have the greatest impact.”
“Risk management should not be a checklist; it should be a strategic allocation of resources aligned with outcomes.”
“European data models show that a targeted approach can deliver both better safety and greater sustainability.”
