Since the 1976 outbreak of Legionnaires’ disease in Philadelphia, data continues to demonstrate how dangerous Legionella pneumophila bacteria can be to the general public.

Recent events involving cooling towers have been highlighted in national news reports. Maintaining clean cooling systems, proper mechanical operation, and chemical programs within design limits are all important aspects of services ChemTreat provides its customers. We remain diligent in our efforts and provide our customers with timely information. Our effort to continue to provide the highest quality water treatment programs begins with each of our sales representatives in connecting to our customers.

LEGIONELLA INFORMATION

The Centers for Disease Control and Prevention (CDC) Morbidity and Mortality Weekly Report (MMWR), June 2016 summarized that from 2000-2014, the rate of reported cases of legionellosis (Legionnaires’ disease and the milder influenza-like illness, Pontiac fever) increased 286%, from 0.42 to 1.62 cases per 100,000 persons in the United States. Still, CDC considers Legionnaires’ disease to be underdiagnosed.

Sources of Legionella Bacteria

Legionella bacteria are found in both natural and manmade water systems. Legionella have been grown between 77°F and 113°F (25°C and 45°C) under laboratory conditions, with optimal temperature growth between 86°F and 108°F (30°C and 42°C).

Guidelines for Legionella Control

ANSI/ASHRAE Standard 188-2015, Legionellosis: Risk Management for Building Water Systems became the first United States Standard to address Legionella. This standard provides a framework to develop a water management plan to minimize risk associated with illness. In addition, other guidelines exist: ASHRAE Guideline 12-2000, Minimizing the Risk of Legionellosis Associated with Building Water Systems; OSHA 1998 guidance, “OSHA Technical Manual, Legionnaires’ Disease”; and Cooling Technology Institute (CTI), WTB-148, Legionellosis Guideline: Best Practices for Control of Legionella Guideline.

Since publication of the standard, New York City and State have enacted regulations to Control Legionella in Cooling Towers and Healthcare Facilities. In June, 2017, Centers for Medicare and Medicaid Services (CMS) published a directive that requires facilities to “develop policies and procedures that inhibit microbial growth in building water systems that reduce the risk of growth and spread of Legionella…”

In addition, Centers for Disease Control and Prevention has updated their Practical Guide to Implementing Industry Standards.
