Protecting your building’s occupants from waterborne pathogens requires vigilance, expertise, and a proactive approach. At SEMS Inc., our comprehensive Legionella testing services provide the critical data facility managers need to maintain safe water systems. By identifying the presence of harmful bacteria early, we help you mitigate risks, ensure regulatory compliance, and prevent the potentially devastating outbreak of Legionnaires’ disease.
Legionella bacteria are naturally occurring but can become a significant health hazard when they proliferate in man-made water systems. If left unchecked, these bacteria can cause Legionnaires’ disease, a severe and often fatal form of pneumonia.
The impact of an outbreak goes beyond public health; it can lead to severe legal liabilities, financial losses, and irreparable damage to your organization’s reputation. Proactive testing is not just a safety measure: it is a critical component of risk management. By implementing a routine testing schedule, you can detect colonization before it reaches dangerous levels, ensuring the safety of your employees, residents, and visitors.
Legionella testing is the scientific process of collecting and analyzing water samples to detect and quantify Legionella pneumophila and related species. This testing is essential to validate the effectiveness of your water management plan and verify that your control measures, such as temperature maintenance and biocide treatments, are working correctly.
Legionella bacteria thrive in warm, stagnant water environments. Our testing protocols focus on the highest-risk areas within your facility, including:
Accuracy is paramount in public health. We utilize rigorous Legionella testing analysis methods that align with current industry standards.
All our testing procedures comply with guidelines set forth by the Centers for Disease Control and Prevention (CDC) and ASHRAE Standard 188.

While any building with a complex water system is at risk, certain facilities face higher stakes due to the vulnerability of their occupants or the complexity of their infrastructure. We provide tailored Legionella testing services for a wide range of industries:
When it comes to environmental safety, you need a partner with proven experience. SEMS Inc. distinguishes itself through a commitment to scientific precision and comprehensive support. We don’t just hand you a lab report; we partner with you to interpret the data and implement solutions.
Our team consists of industrial hygienists and environmental scientists who are rigorously trained in proper sampling protocols. Incorrect sampling can lead to false negatives, leaving your facility exposed to risk. We ensure that samples are collected, stored, and transported according to strict chain-of-custody procedures.
By utilizing Legionella inspection services from certified professionals, you ensure that every potential harborage point — from showerheads to cooling tower basins — is evaluated correctly.
Data is only useful if it is actionable. Our Legionella testing services include detailed reporting that breaks down complex laboratory results into clear, understandable insights.
If Legionella is detected, we provide immediate guidance on remediation steps, such as thermal shock or hyper-chlorination, to bring your system back under control. We help you understand the severity of the findings based on concentration levels and serogroup types, allowing you to make informed decisions quickly.

Testing is not a standalone solution; it is the verification step in a broader Water Management Program (WMP). According to ASHRAE Standard 188, facilities must have a program that identifies hazardous conditions and applies control measures.
Regular testing validates that your WMP is effective. It shows that your control limits (such as temperature and disinfectant levels) are preventing bacterial growth. If you do not have a WMP in place, we can provide comprehensive Legionella risk assessment services to help you build one from the ground up and ensure full compliance with federal and state regulations.
Don’t wait for an outbreak to reveal a problem in your water system. Protect your facility and the people inside it with professional Legionella testing services from SEMS Inc. Our team is ready to help you establish a routine testing schedule that ensures safety and compliance.
