Whirlpool Spa Legionella & Microbiology Testing
Is your whirlpool spa safe and in compliance with regulatory code?
The public may be at risk of Legionnaires’ disease (and other diseases) from exposure to contaminated water in hot tubs or whirlpool spas. These hot tubs may be encountered at hotels, on cruise ships or at home and garden expos. Even if people are not using the hot tubs the mist produced by them may be contaminated with pathogenic bacteria. Exposure to these preventable dangers can create a huge legal liability and expense for your facility. You can prevent the risk to the public and your facility by taking action now. Learn how our Whirlpool Spa Legionella & other microbiological tests for Hot Tubs in Hotels and Cruise Ships can help you assess your facility’s risk.

Below is some information from The Centers for Disease Control and Prevention’s announcement for pool and hot tub operators.
How is Legionella spread in hot tubs?
Legionella is naturally found in water, especially warm water. Hot tubs (or spas) that are not cleaned and disinfected enough can become contaminated with Legionella. A person can get infected with Legionella when they breathe in steam or mist from a contaminated hot tub.
How do I protect myself, my family, and others?
Because high water temperatures make it hard to maintain the disinfectant levels needed to kill germs like Legionella, making sure that the hot tub has the right disinfectant and pH levels is essential. Our Whirlpool Spa Legionella and Other Microbiology Tests in Hotels and Cruise Ships can help determine where you stand.
If You Are A Hot Tub Operator, Ask Yourself the Questions Below
- What was the most recent health inspection score for the hot tub?
- Are disinfectant and pH levels checked at least twice per day?
- Are disinfectant and pH levels checked more often when the hot tub is being used by a lot of people?
- Are the following maintenance activities performed regularly?
- Removal of the slime or biofilm layer by scrubbing and cleaning?
- Replacement of the hot tub water filter according to manufacturer’s recommendations?
- Replacement of hot tub water?

• Whirlpool Spa Legionella & other Microbiology Testing
These microbiology tests provides everything that you need to know, to determine if your spa is code compliant and safe from Legionella and other disease causing bacteria, by including results with interpretation and recommendations. All of these tests can be run from one 250 ml water sample submitted to EST’s Laboratory.
Regulatory Spa Testing (for State, County or City Code)
Total bacterial count (TBC) – provides a measure of the chlorine or bromine disinfection adequacy in the spa. Should be < 200 cfu/ml (colony forming units per milliliter. Recommend WEEKLY sampling unless otherwise directed by code.
Escherichia coli (E. coli) and Total coliforms – public health indicator organisms that are a measure of the contamination of the spa water with bacteria from human feces. The E. coli. should be None Detected or < 0.01 cfu/ml. EST recommends WEEKLY testing unless otherwise directed by code.
- Pseudomonas aeruginosa – a serious human pathogen for both normal and immunocompromised individuals. This pathogen should also be None Detected or < 0.1 cfu/ml. Recommend MONTHLY testing unless otherwise directed by code.
Legionella Spa Testing (for ASHRAE-188 Water Management Programs)
Legionella pneumophila serogroup 1 – Primary Legionnaires disease pathogen should be None Detected or < 0.1 cfu/ml. Recommend QUARTERLY testing unless otherwise directed by your Water Management Program.
Legionella pneumophila serogroups 2-14 – Important Legionnaires disease pathogen should be < 1 cfu/ml. Recommend QUARTERLY testing unless otherwise directed by your Water Management Program.
Legionella (other species) – Important Legionnaires disease pathogenshould be < 1 cfu/ml. Recommend QUARTERLY testing unless otherwise directed by your Water Management Program.
Other Spa-Transmitted Pathogens Testing (as required or requested)
NTM Non-tuberculous Mycobacterium – a group of several different species (Total NTM, M. avium and M. intracellulare) that are found in whirlpool spas and are serious human pathogens for both normal and immunocompromised individuals. Should be None Detected or < 0.1 cfu/ml. Recommend QUARTERLY testing unless otherwise directed by code.
