Legionnaires’ disease bacteria (LDB) – OVERVIEW: Legionella Testing.

Legionella Testing by Aqua Clear, LLC.

Legionnaires’ disease bacteria (aka, Legionella) is a potentially deadly bacteria that is known to thrive in the warm and wet environments created by Cooling Towers.  Because of this, it is extremely important to sufficiently treat the water that flows through cooling towers and to properly clean these systems on a regular basis.  It is also recommended that Legionella Testing be preformed monthly to ensure that there LDB is not present in the system.


Recommended Cleaning/Maintenance from OSHA:

  • Inspect equipment monthly.
  • Drain and clean quarterly or at least twice a year if the unit is not used year round.
  • Treat circulating water for control of microorganisms, scale, and corrosion.
  • Monthly microbiologic analysis is needed to ensure control of biological contamination.


  • Document operations and maintenance in a log book. Log books should list dates of inspections and cleanings, water-quality test results, LDB outbreak investigations, and maintenance.
  • Maintain an up-to-date description of the operating system (which includes all components cooled by the system) and details of the make-up water to the system.
  • Written procedures for proper operation and maintenance of the system should indicate the use of scale and corrosion inhibitors and antifoaming agents. Written records of biocide or chlorine use should be readily available.
