When a patient is discharged, the room is cleaned and prepared for the next occupant. When a maintenance issue is repaired, the work order is closed. When a positive Legionella sample is remediated, many organizations assume the problem has been solved. Unfortunately, water systems do not always work that way. In many healthcare facilities, the plumbing system remembers. Not because pipes can think, but because biofilm, scale, sediment, corrosion, and stagnant water create co

Healthcare facilities spend millions of dollars each year on advanced technology designed to improve patient outcomes. Sophisticated air handling systems. UV disinfection devices. Electronic surveillance software. Water treatment systems. Automated dispensing cabinets. Artificial intelligence tools. These technologies are valuable and often necessary. But there is a surprising reality that infection prevention professionals understand better than most: The most important infe

This week alone, two separate chemical tank failures made headlines. One occurred in Garden Grove and another in Washington. Different facilities. Different systems. Different circumstances. But they all point to the same reality: Accidents and incidents happen. Equipment fails. Tanks rupture. Pumps stop working. Sensors malfunction. Human error occurs. Aging infrastructure deteriorates. Even well-managed facilities can experience unexpected problems. The question is not whet

When people think about Legionella risk in large facilities, they often think first about cooling towers or incoming city water. Those are important, but they are only part of the story. In many buildings, the bigger issue is not simply what enters the facility. It is what happens after the water gets inside. A facility water system is not a straight pipe from the city main to the faucet. It is a complex network of hot water loops, cold water lines, storage tanks, recirculati

When a building water system is working properly, nobody notices. There are no headlines. No emergency meetings. No outbreak investigations. No patients becoming sick from something that should have been preventable. And honestly, that is the goal. In healthcare and large building environments, success in water safety often looks like absolutely nothing happening at all. That may not sound exciting, but behind every quiet day is a tremendous amount of work, planning, monitori

Recent reports of a hantavirus outbreak on a cruise ship are a tragic and sobering reminder of something we don’t talk about enough: Even in 2026, we are not immune to biological risk. First and foremost, situations like this deserve to be approached with respect. These types of outbreaks are often complex, and in many cases, not the result of negligence or error. Some pathogens originate from environmental or external sources that are difficult to predict or fully control. B

In April 2026, the Wynn Las Vegas became the focus of a Legionnaires’ disease investigation after two separate guests were diagnosed following stays at the property. Health officials confirmed that multiple environmental water samples tested positive for Legionella bacteria, triggering immediate remediation efforts inside the facility’s water system. The situation was quickly addressed. The facility implemented cleaning protocols, and follow-up testing showed no detectable Le

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
