International Speakers Announced for Legionella Conference 2019

June 11, 2019

Topics include health care water safety, conservation efforts, cooling tower maintenance and Legionella legal cases

ANN ARBOR, Mich. – An international lineup of public health and sustainability experts from four continents will discuss complex hospital water systems, cooling towers, proactive water quality monitoring and other topics at the Legionella Conference 2019 on Sept. 11-13 in Los Angeles.

NSF International and the National Environmental Health Association (NEHA) will host Legionella Conference 2019: Building Water Systems − The Sustainability & Public Health Nexus to explore the relationship between water conservation and microbial contamination prevention in building water systems.

International experts from government agencies, universities, hospitals and private laboratories in 11 countries are among the scheduled speakers. Organizations represented include the U.S. Environmental Protection Agency, the National Institute of Standards and Technology, Public Services and Procurement Canada, the Network for Public Health Law and the Association of State and Territorial Health Officials (ASTHO).

Water conservation efforts can sometimes have the unintended consequence of amplifying Legionella bacteria growth. The pathogen proliferates in poorly maintained water systems and can cause Legionnaires’ disease, a serious and sometimes fatal flu-like illness that has increased more than five-fold between 2000 and 2017, according to the U.S. Centers for Disease and Prevention Control (CDC). Common sources of contaminated aerosols include cooling towers, low-flow fixtures, shower heads, HVAC systems, decorative spas and fountains.

At the conference, international experts will address a wide range of topics related to building water health and water conservation, including risk assessments, plumbing engineering, communication plans, proactive water quality monitoring, greywater transfers for irrigation and culture change in water safety. Notable presentations include:

Conference panel sessions include:

Technical pre-conference workshops will focus on public health officials’ responses to Legionella outbreaks, case studies and new technology reviews.

The conference will be held at the Los Angeles Westin Bonaventure. Visit for a full list of speakers, topics and other details.
