Frequent Questions

Where can I find information on water quality on airplanes and trains?


In 2009, EPA published the Aircraft Drinking Water Rule (ADWR) to ensure that safe and reliable drinking water is provided to airline passengers and crew. The ADWR provides additional protection to the public from disease-causing organisms (e.g., pathogens) sometimes found in onboard drinking water by establishing barriers of protection targeted to the air carrier industry.


The EPA has worked with railroad companies such as Amtrak, concerning the Federal Safe Drinking Water Act.
