Frequent Questions

Who regulates water on passenger airplanes in the United States?

In the United States, drinking water safety on airlines is jointly regulated by the EPA, Food and Drug Administration (FDA), and Federal Aviation Administration (FAA). EPA regulates the parent systems that supply water to the airports and the drinking water once it is on board the aircraft. FDA has jurisdiction over culinary water (e.g., ice) and the points where aircraft obtain water (e.g., pipes or tankers) at the airport. FAA requires airline companies submit operation and maintenance plans for all parts of the aircraft, including the potable water system. For additional information on regulating water on interstate carrier conveyances please visit the Office of Ground Water and Drinking Water Web site at
