Legionnaires’ outbreaks llinois Veterans deaths, San Quentin Prison

While the Legionnaires’ disease outbreak in the South Bronx has been declared over by New York City officials a week ago, outbreaks of the bacterial respiratory disease has popped up in other areas across the country.

  • It is under diagnosed, and not as rare as you think.
  • Cooling towers, evaporative condensers, humidifiers, domestic/potable hot water systems, fountains, spas, and respiratory equipment are all systems that can harbor and create an active growing environment and support the spread of the Legionella.
  • Legionella cannot be passed between people. It is only transmitted to humans through airborne particles, i.e., inhaling or aspirating contaminated droplets from water systems that have not been properly cleaned and disinfected.
  • Each year, an estimated 10,000 to 18,000 people are infected with the Legionella bacteria in the United States.
  • Up to 30% of these cases prove to be fatal.
  • Legionnaire’s disease can cause cough, high fever, pneumonia, and death. It can be treated effectively with antibiotics.
  • It is preventable.

In recent weeks, events involving cooling towers have been emphasized in the national news. Aqualine remains incredibly thorough and attentive in our efforts to provide our customers with timely information and the highest quality water treatment programs, specifically surrounding Legionella bacteria in building water systems.

Legionella bacteria can be controlled within building water systems by instituting a water management plan that identifies, analyzes and controls the hazards present, including Legionella. The recently published ANSI/ASHRAE Standard 188, Legionellosis: Risk Management for Building Water Systems, outlines compliance requirements for building owners to implement to mitigate the Legionella risks posed by building water systems.

Standard 188-2015 has established minimum legionellosis risk management requirements for building water systems. Standard 188 defines a specific set of practices for analyzing, monitoring, and minimizing the risk of Legionella in building water systems.

Compliance is based on defined criteria. If a building meets any of the listed criteria below, development of a written plan, a Water Management Program (“WMP”), is required. The ASHRAE standard spells out the actions required in the development and documentation of a building(s)’ WMP, as well as exact plan requirements for various kinds of building water systems.


Legionellosis: Risk Management for Building Water Systems

ASHRAE 188-2015 requires building owners to implement and follow a “Water Management Program” if they have any of the following onsite:

  • Cooling Towers and/or Evaporative Condensers
  • Whirlpool Spas
  • Ornamental/Decorative Fountains
  • Air Washers, Humidifiers, or Misters
  • Any other device(s) that release(s) aerosols

Your potable plumbing systems require a Water Management Program if any of the following are true for your building:

  • A centralized hot water system supplying multiple housing units
  • More than 10 stories, this includes below-grade levels
  • Residents over the age of 65
  • Any area(s) housing or administering care to individuals with certain health factors

Aqualine has more than 30 years of industry experience in water management. We are prepared to assist you with ASHRAE Standard 188-2015. We can provide guidance in establishing your WMP by assisting with:

  • Consultation and Education to the “Program Team”
  • Aiding in the description and schematic building of the “Building Water Systems” and “Flow Diagrams”
  • Developing a plan for a comprehensive and ongoing Legionella monitoring program
  • Providing confirmation of control measures at each control location through validation and documentation
  • Support corrective actions when monitoring indicates control parameters are outside limits

Please contact us so we may use our years of expertise to help you meet the Standards requirements while keeping your buildings safe.

News to Know This Week

2 dead from Legionnaires’ outbreak in the Bronx. 31 cases of the flu-like disease have been reported since mid-July: read more here.

Officials Seek Source of Legionnaires’ Outbreak in the Bronx: read more here.

…even as cases of Legionnaires’ have surged in recent years, many buildings have continued to operate under a largely unenforced and often vague patchwork of guidelines, or no rules at all.

“There’s no technical or scientific reason that anyone should ever get sick from the water in their buildings, and yet it happens because we don’t manage the water the way we should,” said William F. McCoy, a longtime Legionnaires’ disease researcher who helped write a new water-management standard for an industry association, the American Society for Heating, Refrigerating and Air-Conditioning Engineers. The new standard, which lays out a process for buildings to develop water-management programs, was also endorsed by the Centers for Disease Control and Prevention.

“Every building in New York City should have a water-management program to protect the occupants in the building from disease and injury,” he added. “But most buildings do not.”
