Phoenix Sky Harbor International Airport was taking immediate and comprehensive actions this week to address the detection of Legionella bacteria and elevated copper levels found in several water sites, according to a news release.
Legionella is a waterborne bacterium found naturally in freshwater environments. There is no immediate risk to public health as there are currently no known cases related to this exposure.
"Phoenix Sky Harbor is committed to maintaining the highest standards of safety and transparency," stated Phoenix Aviation Director Chad Makovsky in a news release. "We are working diligently with health experts and taking all appropriate measures to ensure the well-being of everyone at our airport."
The presence of Legionella and copper was identified during a water quality inspection mandated by the General Services Administration to ensure that the water used in TSA-leased spaces at airports across the country meets stringent health and safety standards.
Findings
Water quality testing, conducted by an independent environmental firm, revealed the presence of Legionella bacteria in nine out of fourteen tested sites, including two publicly accessible water fountains. One site also exhibited copper levels exceeding the EPA standard.
Locations with Positive Legionella Results
TSA breakrooms in Terminals 3 and 4 as well as 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 public health risk is low, and Legionnaires' disease generally is not 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, while 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 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 taken the following actions to address the issue:
- Isolation and Bottled Water : Out of an abundance of caution, water was immediately shut off to impacted areas. Water remains off in those affected areas and bottled water is being provided to employees for their convenience.
- Flushing and Retesting: Comprehensive flushing and retesting of water systems were initiated.
- Faucet Replacement : Faucets in affected areas were replaced as a precautionary measure.
Ongoing and Future Measures
Next Steps
- Continued Flushing and Testing: Systematic flushing and testing of water systems will continue to ensure safety.
- Comprehensive Water Management Program: Engaging a consulting firm to provide contracted expertise and help in continuing to ensure water quality at all airport facilities.
