Legionella Risk Management

Legionella is a serious health risk. In the late 1970s, Legionella, the bacteria responsible for outbreaks of legionellosis and the potentially fatal pneumonia-type illness, Legionnaires’ disease, was first identified. Since then, facilities have become more aware of the risks associated with Legionella bacteria. Under certain environmental conditions, any water system could become a source for Legionella bacteria. Legionella bacteria are common in lakes, ponds, and rivers; however, outbreaks of Legionnaires’ disease rarely originate from these sources. Outbreaks of the illness occur from exposure to Legionella growing in purpose-built systems such as cooling towers, hot and cold-water systems, spa pools and industrial process systems. Water in these systems is maintained at a temperature high enough to encourage growth. Humidifiers, air washers, emergency showers, and ornamental fountains also pose a risk for Legionella bacteria growth. 
 
In addition to health risks to workers, legionellosis outbreaks can have serious financial implications for industrial operations, ranging from health risks, loss of production due to plant shutdowns, damage to the company brand, and in some regions of the world, legal fines.

Solenis’ Legionella Risk Management Experts 

We have an experienced and certified Water Risk Management Team dedicated to helping develop and implement a Water Management Plan that follows with ASHRAE, HSE and other guidance or regulations. Cooling towers, potable water and other water systems will require proper management, biocide selection, monitoring, control and disinfection to comply with the standard. 

Solenis has the qualifications and experience to help you comply with regulations for cooling towers, potable water systems, disinfection, Water Management Plans, etc. Contact us to help you develop and implement a Water Management Plan. 

Frequently Asked Questions

A Water Management Plan (WMP) is a written plan for minimizing the health hazards and risks associated with Legionella and other pathogens in building water systems including domestic water plumbing, cooling towers, decorative fountains, and hot tubs. 

Water Management Plans outline specific control measures to reduce the risk of Legionellosis.  WMPs should be development and implemented following a recognized standard such as ASHRAE 188. 

Developing and implementing a Water Management Plan reduces the risk of disease for people on site (e.g., employees, guests, patients, residents, etc.), reduces legal risk, and helps protect an organization’s public image and revenue. U.S. Centers for Medicaid and Medicare Services (CMS) directive S&C 17-30 (June 2, 2017) requires Medicare certified hospitals, critical access hospitals, and long-term care facilities to develop and implement a Water Management Plan. Some states and cities have regulations that require facilities to implement a WMP. Contact your local Chem-Aqua representative or contact our Water Risk Management Group at 866-209-3373, for more information. 

The ASHRAE 188 WMPs that Chem-Aqua develops do not require Legionella testing.  

However, if required by the AHJ, local/state laws, or desired by the customer, we can accommodate by adding this to the plan. Customers should consult local and state health departments before environmentally sampling for Legionella. Read our blog titled Legionella: To Sample, or Not to Sample?…That is the Question for more information.

EPI Ionization Systems

Copper (Cu) and silver (Ag) have been valued for centuries for their antimicrobial properties. Today, they are used in many industries as an alternative to traditional disinfectants in potable water systems to help manage bacteria, particularly those which cause Legionnaires’ disease. Copper-silver ionization is a proven, effective technology that can reduce bacteria growth without generating halogen-based disinfection byproducts.
