Legionella Conference Special Session

Prevention of Disease and Injury from Waterborne Pathogens During an Emergent Health Crisis

March 9–10, 2021

In response to the current COVID-19 pandemic, NSF and NEHA’s Legionella Conference organizers have added a virtual Special Session to take place on March 9–10, 2021. This 2-day virtual session will center on how industries such as healthcare, water utilities, manufacturing, cultural institutions, and hospitality, as well as health departments  and regulators, can better respond to water-related challenges during a pandemic or major health crisis.

When healthcare, commercial, and industrial facilities experience low to no occupancy, there is the potential for significant impacts on water quality, consumption of water, and operation of building water systems. This session will provide an opportunity for discussion on how we can work together to develop emergency plans and adapt water safety practices to prevent further public health hazards. 

Join the conversation on how to approach water safety and emergency planning during an emergent health crisis. Important topics include: 

  • Water management in healthcare, hospitality, commercial, and industrial facilities during a health crisis. 
  • Sampling strategies for Legionella during and after a shutdown.
  • Conducting and responding to investigations following an extended shutdown.
  • Designing, commissioning, constructing, and renovating to prevent biofilm growth and other hazardous conditions.
  • Safe reopening of buildings and state issued COVID-19 guidance related to water management.
  • Resiliency strategies for returning to normal operation, emergency planning, and risk management.
  • Case studies regarding use of water treatment and processing technologies. 

The conference will include panel discussions, case study reviews, and highlights of new technology.
