  1. Innovative Water Treatment Chemistry with Matheus Paschoalino

    Innovative Water Treatment Chemistry with Matheus Paschoalino

    Can a carbon-negative, bio-based molecule replace legacy phosphonates and help you use less azole—without sacrificing corrosion performance? In this episode, host Trace Blackmore, CWT, welcomes Matheus Paschoalino, PhD Senior Business Development Manager and Microbial Control SME of Solugen, to unpack polyhydroxycarboxylic acids (PHCs) and how they’re changing cooling-water programs from the field up. We cover HEDP replacement in light-duty systems, azole enhancement in copper-challenged waters, a second-generation cut for heavy-duty heat flux, and PHC behavior with oxidizers and non-oxidizer biocides.  From Bioforge to Basin: How PHCs Are Made and Why It Matters  Paschoalino explains Solugen’s chemo-enzymatic “Bioforge” approach that oxidizes sugars (corn-syrup feedstock) into PHCs with very high yield and no practical byproducts—a pathway validated as carbon-negative. He outlines how different “cuts” (monoacid-rich vs. diacid-rich) map to different use cases, and notes current manufacturing capacity and adoption across hundreds of towers.  Replacing HEDP in Light-Duty Programs  For hospitals, HVAC, and other light-duty systems, PHCs have fully replaced HEDP as the anodic corrosion inhibitor while keeping PBTC for scale, enabling lower total phosphorus formulations with equal or better performance compared to status-quo organics.  Azole Enhancement, Free Copper, and Real-World Cost  Field work showed PHCs chelate metals quickly, protecting azole demand when free copper is present (e.g., after oxidizer flushing) and reducing expensive azole overdosing. One university case dropped an adjunct 8-ppm azole feed by pairing the base 3–4 ppm azole with PHC, yielding both corrosion control and lower discharge costs.  Second-Generation PHCs for Heavy-Duty Heat Flux (Toward “Neutral Phosphorus”)  At higher heat flux and stabilized-phosphate conditions, a diacid-rich second-generation PHC proved more stable, enabling orthophosphate reduction and opening a path toward “neutral phosphorus” programs that leverage background phosphate in municipal make-up. Bench data also show synergy with trace metals (e.g., zinc).  Biocide Potentiation and Where It Works Best PHCs remain stable with oxidizers like chlorine dioxide and bleach. Their most compelling synergy shows up with non-oxidizers and peracetic acid (PAA): as a biocide potentiator, PHCs can reduce the need to overdose actives such as THPS, glutaraldehyde, quats, and DBNPA by first complexing interfering metals (e.g., Fe/FeS), letting the biocide perform as intended.  Not “Bug Food”: Pilot Cooling Towers and Oxidizer Demand  To address the industry’s biggest concern with bio-based chemistries, Solugen ran side-by-side outdoor pilot cooling towers under identical bleach control. Result: comparable oxidizer usage and consistently low counts versus HEDP—evidence that PHCs don’t fuel biofilm.  Chelation Mechanics, Polymer Savings, and White Rust  PHCs chelate beyond acid-group stoichiometry thanks to multiple hydroxyls and conformational effects—critical for controlling dissolved metals and protecting films. In stressed heat-flux/chlorine conditions, PHCs reduced calcium-phosphate fouling versus HEDP, often allowing polymer dosage cuts. Early data also show promise for white-rust mitigation on galvanized systems, with the diacid-rich cut delivering the strongest reductions.  For practitioners, the message is pragmatic: PHCs aren’t “lab curiosities.” They’re fielded at scale, enabling lower-phosphorus programs, protecting costly azole inventories, widening the operational window under oxidizer stress, and potentiating select biocides—while staying compatible with common metals.

  3. Raising the Bar: Legionella Management & Industry Standards

    SEP 5

    Raising the Bar: Legionella Management & Industry Standards

    With those words, Jemma Tennant highlights one of the most profound differences between Legionella management in Europe and the United States. In this episode of Scaling UP! H2O, host Trace Blackmore welcomes Jemma Tennant, Chair of the Water Management Society (WMSoc), to explore how legislation, enforcement, and professional training shape the fight against Legionella.   Proactive Regulation and Duty of Care  The UK treats Legionella as a foreseeable and preventable risk. Jemma explains how laws like the Health and Safety at Work Act and COSHH Regulations require mandatory Legionella risk assessments, temperature monitoring, and written control schemes—even when no cases have occurred. This contrasts with the U.S., where ASHRAE 188 serves as guidance rather than enforceable law, often triggering enforcement only after outbreaks.  Jemma shares a case study where a housing association was fined £1.2 million despite no recorded illness, underscoring the UK’s proactive stance on protecting public health. Hospitals, Design, and Emerging Challenges  From hospital plumbing layouts to new “waterless” intensive care units, Jemma details how design choices can either mitigate or magnify waterborne risk. Scotland’s model of involving water safety groups at the design stage provides a proactive example for healthcare worldwide. She also outlines how climate change, net-zero initiatives, and rising ambient temperatures are complicating control strategies across Europe.  Raising Standards Through Collaboration  As Chair of WMSoc, Jemma is leading efforts to raise industry standards and reverse what she calls a “race to the bottom.” She describes partnerships with AWT in the U.S. and LMAG in Australia to share expertise across borders. The episode also explores her pursuit of the Certified Water Technologist (CWT) credential and her vision for adapting the certification for UK professionals.  Conclusion  This conversation is a call to action for water treatment professionals everywhere: regulations, standards, and collaboration matter. Whether in cooling towers, hospitals, or housing estates, Legionella management requires vigilance, shared knowledge, and a commitment to raising the bar.

  4. Optimizing Legionella Control Strategies with Dr. Vincenzo Romano Spica

    AUG 29

    Optimizing Legionella Control Strategies with Dr. Vincenzo Romano Spica

    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.  Stay engaged, keep learning, and continue scaling up your knowledge!    Timestamps    02:24 - Trace opens the episode, welcoming listeners to Legionella Awareness Month and framing the call to action  05:37 - Water You Know with James McDonald  10:04 - Upcoming Events for Water Treatment Professionals   14:06 - Trace introduces Dr. Vincenzo Romano Spica, Head of Public Health at the University of Rome Foro Italico   17:22 - Dr. Spica outlines why Legionella pneumophila is the main pathogen of concern in Europe 35:04 - Dr. Spica explains Disability Adjusted Life Years (DALYs) as a measure of public health burden  44:08 - Monitoring strategies and how different culture methods affect outcomes  46:16 - The role of water temperature in Legionella proliferation    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.”    Connect with Dr. Vincenzo Romano Spica   Phone: +39.06.36733247 Email: vincenzo.romanospica@uniroma4.it  LinkedIn: vincenzo romano spica | LinkedIn        Guest Resources Mentioned   Legionnaires’ Disease Surveillance and Public Health Policies in Italy: A Mathematical Model for Assessing Prevention Strategies by Dr. Spica et. al  Alessando Cassini’s Burden of Infectious Diseases in Europe methodological challenges and opportunities for public health policy  NLM’s Impact of infectious diseases on population health using incidence-based disability-adjusted life years (DALYs): results from the Burden of Communicable Diseases in Europe study, European Union and European Economic Area countries, 2009 to 2013  Supplemental information: Impact of UAT Diagnostic Methods on Estimates of Legionnaires’ disease Caused by non-pneumophila Legionella    Scaling UP!

  5. Encore Interview with Patsy Root

    AUG 22

    Encore Interview with Patsy Root

    “Rules written in a panic rarely stand the test of time.”   In this encore episode, Trace Blackmore welcomes back Patsy Root, Senior Manager of Government Affairs at IDEXX Water and active member of the AWT Legislative and Regulatory Committee. Patsy brings global data, case studies, and clear recommendations for smarter Legionella regulation — and why a targeted focus on Legionella pneumophila can save both lives and resources.   From Outbreaks to Proactive Policies  Patsy unpacks a central truth: most regulations emerge reactively, often after a high-profile outbreak. Drawing on her research from the U.S., Canada, and Europe, she compares different jurisdictions’ approaches — from Quebec’s targeted testing mandate to New York City’s broader species-based rule — and reveals why some frameworks reduce cases far more effectively than others.  The Case for Targeted Testing  Legionella encompasses around 60 species, but not all carry equal risk. Patsy explains why L. pneumophila — the species most responsible for Legionnaires’ disease — demands priority in monitoring and control. Through examples from France, Germany, the UK, and beyond, she demonstrates how focusing on the pathogen itself, rather than all species, leads to measurable public health gains and cost savings.  Educating Lawmakers and Industry  Beyond technical data, Patsy emphasizes the importance of water professionals engaging with legislators. She outlines how clear communication, evidence-based recommendations, and standards like ASHRAE 188 can guide practical, enforceable rules. Her advice balances science with real-world feasibility, helping both regulators and facility managers protect health without unnecessary expense.  This conversation is more than a policy discussion — it’s a blueprint for better public health protection through smart, focused water management.

  6. Legionella investigations and LIDO Technology

    AUG 15

    Legionella investigations and LIDO Technology

    What if preventing Legionella outbreaks wasn’t about adding more chemicals, but removing what the bacteria needs to survive? In this episode of Scaling UP! H2O, host Trace Blackmore talks with Dr. David Krause, Certified Industrial Hygienist, toxicologist, and founder of HC3, about his groundbreaking approach — LIDO (Legionella Inhibition by Deoxygenation). Legionella on the Rise  Dr. Krause has investigated high-profile Legionella outbreaks and seen firsthand how current prevention strategies often fall short. Despite ASHRAE 188 standards, CMS requirements, and increasing water management plan adoption, Legionella cases continue to climb — often due to infrastructure issues, insufficient monitoring, and a lack of evidence-based guidance.  Inside an Outbreak Investigation  From the first call at 4:30 on a Friday to the coordination between local health departments, state agencies, and the CDC, Krause explains the rigorous (and sometimes chaotic) process of pinpointing outbreak sources. He also reveals why public communication can make or break an outbreak response.  Introducing LIDO Technology  Rather than relying solely on chemical disinfection, LIDO uses gas transfer membrane contactors to remove dissolved oxygen from hot water systems. Legionella can’t thrive below 0.3 ppm DO — meaning systems treated with LIDO create an inhospitable environment for growth. Krause shares lab results, pilot project findings, and how this approach could extend system life while reducing corrosion and byproducts. The Bigger Picture  This episode goes beyond technology — it’s about rethinking water management, building better outbreak communication, and challenging industry norms. Whether you’re a facility manager, water treater, or public health professional, Krause’s insights will shift the way you think about Legionella control.   Prevention starts with awareness — and action. Dr. Krause’s work shows there’s more than one path to safer water systems, and innovation comes from asking better questions.  Listen now to discover how Legionella investigations unfold and how LIDO technology could reshape prevention.

  7. Water Management Plans: Evolving Standards and Best Practices with Matt Freije

    AUG 8

    Water Management Plans: Evolving Standards and Best Practices with Matt Freije

    "Just because you have a water management plan doesn’t mean it’s working."  That’s the hard truth Matt Freije, founder and CEO of HC Info, delivers in this episode of Scaling UP! H2O. As the architect behind LAMPS — a leading cloud-based platform for water management programs — Matt joins Trace Blackmore to explore the critical evolution of water safety, compliance standards, and real-world implementation challenges facing facilities in 2025.   Beyond the Binder: Water Management Plans That Actually Work  In an era of heightened awareness and shifting regulations, simply checking the compliance box is no longer enough. Matt walks us through the CDC data and ASHRAE findings that make a strong case for active, ongoing water management — not just documentation. Drawing from recent outbreak investigations, he explains why implementation, not content, is often the root failure.  Trace and Matt discuss the widespread misconception that water management plans guarantee zero Legionella. They also address the real barriers preventing facilities from taking action — from budget limitations to internal roadblocks — and what water professionals can do to influence smarter, risk-based decisions. Regulatory Pressure, AI Integration, and What’s Coming Next  With ASHRAE 514, AAMI ST108, and ASSE 12080 gaining ground, the water industry is seeing increased scrutiny, especially in healthcare and hospitality facilities. Matt outlines how these evolving standards are transforming expectations and forcing a shift in accountability.  The conversation takes a forward-looking turn as they explore the power of AI and aggregated analytics to optimize pathogen control. With 10,000 buildings in the LAMPS system, HC Info is preparing to offer data that could shape public health outcomes nationwide — a move that could redefine how we benchmark performance and interpret Legionella test data at scale. Culture, Purpose, and Long-Term Vision  As a mechanical engineer with an epidemiology background, Matt also reflects on the human side of leadership — from building a values-driven team to embracing his faith as a cornerstone of decision-making. His message for water treaters is clear: “Either do it well or don’t do it.”  For facilities leaders, his advice is to stop fearing complexity and start leveraging the tools available — because water management done right can improve not just compliance, but health outcomes, asset longevity, and operational resilience. Conclusion  This episode is a masterclass in how to future-proof your water safety strategy. With actionable insights, emerging technologies, and a clear call to accountability, Matt Freije reminds us that smart water management is both a technical responsibility and a moral imperative.  Listen to the full conversation to understand how new standards, digital tools, and intentional leadership are shaping the future of water safety.

  8. Legionella Awareness Month Kickoff! Guest Name: Trace Blackmore

    AUG 1

    Legionella Awareness Month Kickoff! Guest Name: Trace Blackmore

    Are You Ready to Talk About Legionella?  Every August, we dedicate an entire month to a topic that touches public health, liability, and the core of what water treaters do — yet it’s still misunderstood by many: Legionella.  In this episode, Trace Blackmore kicks off Legionella Awareness Month by returning to the basics. Where did Legionella get its name? What makes it dangerous? And why is there still confusion between a water treatment program and a water management plan?  Tracing It Back: History, Misconceptions, and Missed Conversations  Trace opens with the 1976 American Legion outbreak in Philadelphia — the moment the medical and water treatment worlds collided. He explains how the bacteria was identified, how the term Legionella pneumophila came to be, and how Pontiac Fever and Legionnaires’ Disease represent two ends of the same pathogenic spectrum.  But more importantly, he challenges us to think critically about the language we use. Saying “Legionella” casually — without understanding whether we’re referring to the bacteria, the illness, or the implications of a test result — can lead to major breakdowns in communication between service providers and facility managers.  A Water Treatment Program Is Not a Legionella Plan  Many professionals know how to deliver great chemical treatment. But too often, when a Legionella test comes back positive, the customer assumes the water treater is responsible. This episode explains how that misunderstanding happens—and how to prevent it through proactive, well-framed conversations.  Trace walks through why seasonal testing is the bare minimum, what makes a good water management team, and why documentation and pre-approved action plans are essential for clarity and peace of mind when results come in.  He also introduces tools like the CDC Legionella Toolkit, ASHRAE 188, and ASSE 12080—resources every industrial water professional should know and use.  The Systems at Risk — And Why It’s Not Just Cooling Towers  Trace breaks down the environments where Legionella thrives cooling towers, stagnant pipes, dead legs, hot water systems with low temperatures, decorative fountains, humidifiers, and spas. He highlights why biofilm protection matters, why heat isn’t always enough, and how mixing valves and plumbing design can support both safety and scald prevention.  You’ll hear how real-world scenarios unfold—and how one positive test, without the right planning, can lead to panic, blame, and liability risk for everyone involved.  Legionella isn't just a technical issue — it's a human one. Whether you’re in the field, managing accounts, or advising clients, this episode offers practical tools and powerful reminders for having the conversations that count.  The professionals who lead these conversations are the ones building trust, avoiding risk, and elevating the industry.   Listen to the full episode and explore the Legionella Resource Library at Legionella Resources.

By then, emotions are already high.”  “ASHRAE 188 doesn’t prescribe. It describes it. It’s up to us to translate it for each system.”  “Education isn't just about reading guidelines. It’s about knowing how to guide your clients.”    Connect with Scaling UP!
