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...

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...

info_outline“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.

Quotes
“The worst time to write a rule is when you’re in the middle of a panic.”
“Finding Legionella species is not the same risk level as finding L. pneumophila — and the data prove it.”
“Keep the hot water hot, keep the cold water cold, keep the water moving, and keep a decent disinfectant.”
“Biology fascinates me — the fact that bacteria can signal each other to come join a good spot is both creepy and amazing.”
“When lawmakers understand how preventable this disease is, they can become champions for real change.”
