Arthur Freedman Associates provides building owners and facilities managers with independent consulting services for the control of Legionella bacteria in commercial and industrial water systems. An AFA Principal Consultant, Bob Cunningham was actively involved in the development of the “ANSI/ASHRAE Standard 188-2015 Standard Legionellosis: Risk Management for Building Water Systems.” The combined team has decades of consulting experience in the control of Legionella and other microbiological pathogens, and the prevention of Legionnaire’s Disease outbreaks.


We recommend that Facilities Managers implement a comprehensive and defensible Legionella Water Management Plan (WMP) to minimize the risk of Legionnaires’ disease, and comply with the ANSI/ASHRAE Standard 188-2015 in order to protect your organization’s image and to minimize your legal risk. AFA has partnered with HC Info and with Special Pathogens Lab (SPL) to provide independent WMPs for our customers, as these plans are of the highest quality and credibility available anywhere.

AFA also provides Water Management Plans and WMP Certification Services designed to meet the regulatory requirements for cooling towers in New York City and New York State. If you had a WMP developed for you by your water treater or chemical supplier, to avoid receiving citations and fines for possibly not meeting the NYC/NYS regulatory requirements, we particularly recommend that you engage with AFA to provide a quarterly WMP review and HVAC system audit, and obtain your annual WMP Certification from Arthur Freedman Associates.
