The U.S. Environmental Protection Agency is issuing a final rule to ensure that safe and reliable drinking water is provided to aircraft passengers and crew. The rule provides multiple-barrier protection through requirements for coliform sampling, best management practices, corrective action, public notification, monitoring and operator training. It hopes to better protect the public from illnesses caused by microbiological contamination.

The final aircraft drinking water rule tailors existing health-based drinking water regulations to fit the unique characteristics of aircraft public water systems. Aircraft public water systems are subject to the requirements of the National Primary Drinking Water Regulations (NPDWRs) under the Safe Drinking Water Act. The rule amends NPDWRs for these systems, building on existing aircraft operations and maintenance programs.

The rule applies to the aircraft’s onboard water system only. The Food and Drug Administration is responsible for regulating the airport watering points that include the water cabinets, carts, trucks and hoses from which aircraft board water. EPA and the states are responsible for regulating the public water systems that supply drinking water to the airport watering points.

The rule only addresses aircraft within U.S. jurisdiction; however, EPA supported an international effort led by the World Health Organization to develop international guidelines for aircraft drinking water.
