Pathogens found in cooling towers are not only detrimental to the cooling system metal alloy components and energy efficiency; specific pathogens, for instance, Legionella bacteria, have emerged to be detrimental to human health. Cooling tower drift and bleed-off water can also inoculate the environment with dangerous pathogens.

ASHRAE Standard 188 was finalized as the standard of care to be used by building owners and managers in assessing the risks associated with waterborne pathogens. CH2O, Inc. has partnered with HC Info to provide a written plan for minimizing Legionella and other pathogen risks in your water systems based on the World Health Organization's 2007 publication, VHA Directive 1061, and ANSI/ASHRAE 188-2015.
