Screen building water for the bacteria behind Legionnaires' disease.
Legionella causes Legionnaires' disease, a severe and sometimes fatal pneumonia, plus the milder Pontiac fever. It grows in warm stagnant water - water heaters, large plumbing systems, hot tubs, and cooling towers - and infects people by inhaling contaminated aerosols (e.g., showers).
Risk is highest for older adults, smokers, and people with weakened immune systems or lung disease. Buildings that sat idle (vacations, closures) are a known risk because stagnant water lets Legionella bloom.
Fill the sterile 250 mL bottle from the target fixture (shower, tap, cooling system) following the instructions, keep it cold and shielded from light, and ship the same day.
The lab cultures the sample on Legionella-selective media and confirms with PCR, reporting colony-forming units - aligned to ASHRAE Standard 188 and CDC water-management guidance.
Independently operated, with no ties to filter or remediation companies. Every sample is analyzed by an accredited partner laboratory under EPA-referenced methods, with a documented chain of custody — and your data is yours.
