Legionella Testing
Legionella bacteria are commonly found in natural and building water systems, and they can pose a serious health risk when conditions allow them to multiply. These bacteria are the primary cause of Legionnaires’ disease, a severe and potentially fatal form of pneumonia.
At PITS Environmental, our CDC ELITE–certified laboratory provides highly accurate Legionella testing using validated culture-based methods. Our testing process is further supported by an ASSE 12080–certified Legionella Water Safety & Management Specialist, ensuring that every assessment meets the highest national standards for water safety, risk management, and regulatory compliance.
We deliver reliable, science-driven Legionella testing solutions to help building owners, facility managers, and healthcare institutions maintain safe, compliant, and well-managed water systems.

Frequently Asked Questions
What is Legionella, and why is it dangerous?
Legionella is a waterborne bacterium that can cause Legionnaires’ disease, a serious respiratory infection. It becomes dangerous when it grows in building water systems and is inhaled through contaminated droplets.
How is Legionella testing performed by a certified lab?
Legionella testing is conducted using culture-based and rapid detection methods. Our CDC ELITE-certified laboratory follows validated procedures to accurately identify Legionella species in potable and non-potable water systems.
How often should Legionella testing be done in buildings?
Healthcare, hospitality, and commercial buildings should test at least every 3–12 months, depending on risk level, system complexity, and regulatory requirements. High-risk facilities benefit from quarterly testing.
What are the symptoms of Legionnaires’ disease?
Symptoms include cough, fever, shortness of breath, headache, muscle aches, and pneumonia. Early detection of Legionella in water systems helps reduce outbreak risks.
Can you test for bacteria like Legionella in my water system?
Yes. Our CDC ELITE-certified lab performs Legionella culture testing, molecular analysis, and microbial assessments to detect harmful bacteria in building water systems.
Is Legionella testing mandatory for certain facilities?
Many healthcare facilities, long-term care centers, hotels, and industrial buildings are required to perform routine Legionella testing under ASHRAE 188, CMS, and local public health regulations.
How long does professional Legionella testing take?
Standard culture results typically take 7–10 days, while rapid screening methods may provide preliminary insights within 24–48 hours.
How much does Legionella testing cost?
Costs vary depending on the number of samples, type of water system, and analysis required. Pricing options are available for routine monitoring and comprehensive risk assessments.
How can I prevent Legionella contamination in my water system?
Prevention involves temperature control, disinfection, flushing routines, and a properly managed Water Management Program. Our ASSE 12080-certified Legionella Water Safety Specialist can help design and implement compliant WMPs.
Are your Legionella services compliant with CDC, OSHA, and ASHRAE guidelines?
Yes. Our services follow CDC ELITE testing standards, OSHA safety practices, and ASHRAE Standard 188 requirements. We also provide expert guidance from an ASSE 12080-certified Legionella Water Safety Specialist to ensure full regulatory compliance.
