Airplanes: In tests reported in January 2005, one in six airliners had drinking water that failed to meet federal safety standards set by the U.S. Environmental Protection agency.
Although the agency’s guidelines suggest that testing be done quarterly, or at least that the water systems be flushed and disinfected quarterly. A published report in 2004 indicated that it wasn’t clear how often either has been happening.
Ships: The Vessel Sanitation Program of the CDC includes detailed guidelines about how water takes can be constructed, where ships can make freshwater from seater and how often the water has to be tested. The program conducts unannounced inspection of cruise ships twice a year. The results are available at www.cdc.gov/nceh.vsp
