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

Biofilm Awareness Week is the perfect reminder that one of the most dangerous threats in your water system is also one of the hardest to see. Biofilm is the foundation that allows Legionella , Pseudomonas , and other waterborne pathogens to survive, multiply, and spread inside hospitals and long-term care plumbing systems. At Legionella Specialties , we help healthcare facilities identify, monitor, and reduce biofilm so they can stay compliant, survey-ready, and patient-safe.

Legionella prevention  is not a summer-only job. In healthcare and long-term care environments, winter operations  can quietly increase Legionnaires’ disease risk  because of stagnation , tepid water zones , and residual decay  in building plumbing. Infection prevention leaders who treat winter like a lower-risk season often miss early warning signals that precede colonization and clinical cases. Why winter can raise Legionella risk in healthcare water systems Lower occupancy

Across the country, cities and states are tightening regulations around Legionella prevention. These updates are driven by a rise in outbreaks, more advanced testing capabilities, and the growing recognition that outdated monitoring schedules leave facilities exposed. The newest example comes from New York City, where officials have enacted stricter testing laws designed to prevent a repeat of deadly Legionnaires’ disease outbreaks. The increased attention on water safety is

Every October, we brace for the ghosts and ghouls that come out after dark, but in healthcare facilities, the real monsters don’t wait for Halloween. They lurk in the shadows of your water system: invisible, evolving, and ready to strike when conditions are just right. This year, as hospitals and care facilities battle staffing shortages and rising infection rates, it’s more important than ever to shine a flashlight into the dark corners of your building’s plumbing and make s

Turning water-system signals into actionable foresight For decades, water-safety programs have been largely reactive: sample, wait for results, respond. While this approach confirms problems, it often fails to prevent them. Today, premise-plumbing managers can get ahead of Legionella by using routine water-quality measurements, continuous sensor data, and analytics to predict when and where colonization is likely to occur. Predictive monitoring does not replace culture or PCR

The Stream Analogy: Where the Water Is Cleanest Imagine a clear mountain stream. At its source, the water is pristine, cold, fresh, and full of oxygen. But as that stream travels 100, 200, or 300 feet downstream, it picks up soil, debris, leaves, and microorganisms. The further it flows, the more it changes. Now think of your facility’s plumbing the same way. It doesn’t matter how clean the water is when it enters the building if hundreds of feet of warm, stagnant pipes and b
