Phoenix Sky Harbor International Airport (PHX) is taking immediate and thorough measures to address the detection of Legionella bacteria and elevated copper levels in several water sites. This proactive approach underscores the airport’s commitment to maintaining a safe environment for all passengers, employees, and visitors.
Legionella, a waterborne bacterium commonly found in freshwater environments, was detected during a routine water quality inspection mandated by the General Services Administration (GSA). The inspection ensures that the water used in TSA-leased spaces at airports nationwide meets stringent health and safety standards. There is no immediate risk to public health as no known cases of Legionnaires’ disease have been reported in connection with this exposure.
“Phoenix Sky Harbor is committed to maintaining the highest standards of safety and transparency,” said Chad Makovsky, City of Phoenix Aviation Director. “We are working diligently with health experts and taking all appropriate measures to ensure the well-being of everyone at our airport.”
Findings
Water quality testing by an independent environmental firm revealed the presence of Legionella bacteria in nine out of fourteen tested sites, including two publicly accessible water fountains. Elevated copper levels were also detected at one site, exceeding the EPA standard.
Locations with Positive Legionella Results:
- TSA break rooms in Terminals 3 and 4
- Two post-security public water fountains in Terminal 3
Health Information
Legionella bacteria are common in water systems and can cause Legionnaires’ disease when inhaled through aerosolized water droplets. The risk to public health is low, as Legionnaires’ disease is not typically spread from person to person. According to the Maricopa County Department of Public Health, there are currently no known cases of Legionnaires’ disease linked to Phoenix Sky Harbor International Airport.
Elevated copper levels, although uncommon in drinking water, can pose health risks if consumed in large quantities over time. Immediate measures are being taken to mitigate any potential health risks from the elevated copper levels in the affected area.
“There is no current threat to the water supply, and all water quality parameters associated with the drinking water system are within normal operating ranges,” said Phoenix Water Services Director Troy Hayes. “The elevated levels of Legionella and copper were isolated to specific areas, and we are confident in the safety of the overall water system.”
Immediate Actions Taken
The health and safety of the airport community is of the utmost importance. Phoenix Sky Harbor International Airport has implemented the following measures to address the issue:
- Isolation and Bottled Water: Out of an abundance of caution, water was immediately shut off to impacted areas. Bottled water is being provided to employees in these areas.
- Flushing and Retesting: Comprehensive flushing and retesting of water systems have been initiated to ensure safety.
- Faucet Replacement: Faucets in affected areas have been replaced as a precautionary measure.
Ongoing and Future Measures
- Continued Flushing and Testing: Systematic flushing and testing of water systems will continue to ensure ongoing safety.
- Comprehensive Water Management Program: The airport is engaging a consulting firm to provide expertise and help maintain water quality at all facilities.
Phoenix Sky Harbor International Airport remains dedicated to ensuring the highest standards of health and safety for everyone who passes through its doors. The proactive steps taken demonstrate a robust response to maintaining a secure and safe environment.
