Most healthcare water management programs are built around a familiar framework: incoming water quality, hot water temperatures, storage, disinfectant residuals, and distal outlet testing. And for good reason, those are critical control points. But there is a growing recognition in both guidance and research that one of the most overlooked risk areas in healthcare isn’t upstream in the system… It’s right below the faucet. Why This Matters Now Recent updates from the Centers f

Most water management strategies are built around a simple assumption: Legionella is something that shows up, gets detected, and then gets addressed. The problem is that assumption is wrong. Legionella is not a one-time event. It is a continuous input. It Only Takes 72 Hours Under the right conditions, Legionella can double every 6 to 8 hours. That means a single viable cell can multiply into a detectable colony in as little as 72 hours. Let that sink in. This is not a slow-m

Most healthcare facilities prepare for surveys. Far fewer are prepared for what happens between them. As of 2026, The Joint Commission continues to enforce water management expectations under standard EC.02.05.02 , supported by Centers for Medicare & Medicaid Services requirements and Centers for Disease Control and Prevention guidance. These are not new rules. What has changed is how strictly they are evaluated in real-world conditions. Surveyors are no longer asking if you

When it comes to Legionella control, most conversations start and end with hot water systems. Maintain temperatures above 124°F. Balance return loops. Monitor distal outlets. All important. All necessary. But focusing only on hot water systems creates a dangerous blind spot. Because in many buildings, the problem doesn’t always start in the hot water system. It starts in the cold. Cold Water Is Not “Safe Water” There is a long-standing assumption in building water management

In Legionella prevention, everyone knows to look for dead legs. They are visible, easy to explain, and widely recognized as a risk. But many of the most persistent problems in building water systems are not found in fully stagnant branches. They show up in areas that technically still have movement, but not enough of the right kind of movement. At Legionella Specialties, we often use the phrase “ghost flow”  to describe these conditions: sections of plumbing where water is no

Over the past several decades, infection prevention programs in healthcare facilities have made enormous progress. Hospitals have dramatically improved hand hygiene compliance, sterilization practices, and patient isolation protocols. These efforts have saved countless lives and reduced the spread of healthcare-associated infections. But despite these advances, infection prevention is still an evolving discipline. As our understanding of pathogens grows, so does our awareness

When people think about spring cleaning, they usually picture deep cleaning floors, organizing storage areas, and catching up on maintenance tasks that were pushed aside during the winter months. But one of the most important systems in a healthcare facility is often overlooked during seasonal maintenance: the building’s water system. Hospital plumbing systems operate year-round, quietly delivering water to hundreds or even thousands of outlets. However, behind the scenes, th

For decades, healthcare water safety programs have focused on microbial risks such as Legionella, Pseudomonas, and other opportunistic pathogens. While these threats remain critical, another category of concern is gaining attention across the water industry: PFAS. PFAS, or per- and polyfluoroalkyl substances, are often referred to as “forever chemicals.” These compounds have been widely used in industrial manufacturing and consumer products since the 1940s because of their re

Healthcare water management is no longer optional. It is no longer informal. And it is certainly no longer limited to a binder sitting on a shelf. Today’s environment demands clarity in four critical areas: Rules. Compliance. Testing. Treatment. Each one plays a role. When one is weak, the system becomes vulnerable. Here is what that looks like in practice. 1. The Rules: Understanding the Regulatory Landscape Healthcare facilities are operating under increasing regulatory exp

Hospitals test patients constantly. Blood work. Cultures. Panels. Labs. Because in medicine, you never assume. You measure. Yet when it comes to building water systems, the very systems delivering water to immunocompromised patients, many facilities rely on assumptions: Our chlorine levels are fine. We shocked last quarter. We have not had complaints. Our Water Management Plan is in place. Without testing, you are guessing. And in infection prevention, guessing is risk. Water

At Legionella Specialties , Chasing Zero  is defined very simply: Zero means that any Legionella test we send to an accredited laboratory comes back as non-detect after treatment. Not reduced counts. Not “within acceptable limits.” Not “below an action threshold.” Zero. Chasing Zero is the intentional pursuit of laboratory-verified, non-detect Legionella results across an entire water system following treatment. If a sample is collected, submitted to the lab, and analyzed, th

Infection Preventionists (IPs) are often the unseen force protecting patients, staff, and visitors every single day. Their work doesn’t always make headlines but when it’s done well, outbreaks are prevented, lives are protected, and healthcare systems keep moving safely. IPs sit at the intersection of science, policy, operations, and human behavior . They translate evolving guidelines into real-world practice, monitor risk across complex environments, and respond quickly when

For many healthcare facilities, survey readiness has become the unofficial benchmark for success in water management. If the survey goes well, the program must be working. If there are no findings, risk must be under control. But passing a survey and controlling Legionella risk are not the same thing. At Legionella Specialties , we work with facilities that have strong teams, good intentions, and recent survey success. Yet many of those same facilities still experience recurr

Most facilities don’t ignore water safety. They have plans. They have committees. They have vendors. They’ve done the training. They’ve got a binder on a shelf and a folder in SharePoint. And yet Legionella still shows up. Not because people don’t care, but because many Water Management Programs are not built to operate like an actual operational control system. They are built like a document. The standards are clear. Facilities need a program that identifies risk points, app

As we move into early 2026, one thing is clear: Legionella risk has not gone away, it has simply shifted back into familiar, but often overlooked, areas . Across healthcare, commercial, and institutional facilities, recent public alerts and risk discussions continue to center on cooling towers, reduced-occupancy operations, and water system oversight gaps . For facility leaders, infection prevention teams, and risk managers, this is a critical time to reassess water managemen

Protecting Employees, Clients, and Products in Large Buildings & Manufacturing Facilities When most people hear Legionella , they immediately think of hospitals or healthcare facilities. But the reality is this: Legionella does not discriminate by industry . Any large building with a complex water system can become a risk environment if water safety is not actively managed. Manufacturing plants, warehouses, corporate campuses, hotels, schools, government buildings, and indust

The start of a new year is the perfect time for healthcare facilities, long-term care communities, and large building operators to pause, reassess, and strengthen their approach to water safety. While many organizations focus their new year planning on budgets, staffing, and operational goals, building water systems are often overlooked until a problem occurs. Unfortunately, waterborne pathogens such as Legionella do not wait for warning signs. They develop quietly within plu

Hospitals are designed to save lives, but many are quietly aging in ways that don’t show up on balance sheets or floor plans. Deferred maintenance is often discussed in terms of budgets, capital planning, and aesthetics. What gets talked about far less is how deferred maintenance impacts infection prevention and water safety. In building water systems, delay is not neutral. It actively changes conditions inside the pipes. Deferred Maintenance Isn’t Just Broken Equipment It’s

Healthcare facilities are under more pressure than ever to maintain safe, compliant water systems. That’s why we are excited to announce the publication of our latest research article, “Mineral Oxychloride: A Continuous Disinfection Method for Legionella Control in Healthcare Water Systems.” This peer-reviewed study analyzes real-world data from active hospital water systems and demonstrates how continuous low-dose mineral oxychloride delivers measurable, consistent control o

Across hospitals and long-term care facilities, water safety programs are shifting from “write the plan” to prove the plan works . With tighter regulatory expectations under ASHRAE 188 , the Joint Commission R3 report , and ST108 , flushing is no longer a “nice to have”, it’s a measurable, trackable control measure that directly impacts patient safety and regulatory compliance. And yet, most facilities either don’t flush enough , don’t flush consistently , or don’t document i
