  • 435 Optimizing Legionella Control Strategies with Dr. Vincenzo Romano Spica

    435 Optimizing Legionella Control Strategies with Dr. Vincenzo Romano Spica
    Aug 29 2025
    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.

    434 Encore Interview with Patsy Root
    Aug 22 2025
    “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. Whether you work in compliance, operations, or advocacy, Patsy’s insights will equip you to engage in the legislative process with clarity and authority.

    433 Legionella Investigations and LIDO Technology
    Aug 15 2025
    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.
