These Airlines Have the Dirtiest Onboard Drinking Water

October 13, 2019

Submit to: Maybe you don’t want to know. The 2019 Air Water Research from the Hunter University Food Policy Center and DietDetective.com ranked the safety of onboard water for ten major airlines. This is… something that most people might not think of. After all, is the drinking water on board not from the kettle?

Usually, yes. However, all airlines have huge on-board water tanks for kitchen faucets (mainly used for making coffee and tea, sometimes for making ice), bathrooms, and for drinking water. The EPA has even implemented the Aircraft Drinking Water Regulations (ADWR), which requires airlines to sample onboard water to detect coliforms and E. coli, and to flush and disinfect the tank four times a year (if tested, once a year) More).

The study ranked 11 major airlines and 12 regional airlines through the Water Health Score based on 10 criteria, including fleet size, airline violations of ADWR, positive E. coli and coliforms Water sample report and the will of the airline. Answer the water quality question.

So what about water? It depends on the airline you are travelling on.

“Alaska Airlines and Allegiant won the top spot with the safest water in the sky, and Hawaiian Airlines won second place,” Dr. Charles Platt King, Ph.D., JD, Department of Public Health and Hunter, NY The executive director of the College Food Policy Center said. Spiritual Aviation and (perhaps surprisingly) JetBlue scored the lowest.

This is the complete ranking of drinking water on airlines and their scores (zero is the lowest and five is the highest). According to the study, a score of 3.0 or higher indicates that the airline has relatively safe, clean water.

Alaska Airlines: 3.3
Loyalty to aviation: 3.3
Hawaiian Airlines: 3.1
Frontier Airlines: 2.6
Southwest Airlines: 2.4
Delta Airlines: 1.6
American Airlines: 1.5
United Airlines: 1.2
JetBlue: 1
Spirit Airlines: 1
The study also pointed the finger at the EPA itself, saying: “The Environmental Protection Agency – one of the federal agencies responsible for ensuring safe drinking water for aircraft – violating ADWR rarely imposes civil penalties on airlines,” and further endows “shame” to EPA and major aviation The company has selected “Your Winners”, “because their response time is very short and there is a lack of cooperation to answer detailed questions.”

For travelers who are concerned about the water quality on board, the study puts forward three suggestions: “Don’t drink any water without a sealed bottle on the boat, don’t drink coffee or tea on the boat, don’t wash your hands in the bathroom; carry hand sanitizer with you.”
