Right on track
by Jennie Saxe
I love traveling by train. Here in the Northeast, I’m a little spoiled by the many rail transit systems that spider-web across the region. But with family in New England, my office in Philadelphia, and friends in Washington, DC, one of my favorite modes of transportation is Amtrak.
Here’s a fun water-related fact about traveling on Amtrak: every passenger rail car that has a café, restroom, or drinking fountain is considered its own public water system. Amtrak has about 1,500 of these mobile water systems, each of which must be monitored for water quality. Detailed maintenance procedures and monitoring plans are key to protecting public health, as trains roll from coast to coast.
Amtrak has been randomly sampling drinking water for over 20 years, and has been following a more detailed schedule and reporting results to EPA since 2012. Recently, EPA and Amtrak amended the 2012 agreement to extend the monitoring requirements and modify sampling schedules based on the results from all 1,500 cars to date: very few samples from 2013 and 2014 were positive for coliform bacteria (an indicator that something could potentially be wrong with the water) and no samples were positive for E. coli (a bacteria that signals contamination, and could make passengers sick).
Some additional protections are part of the agreement between EPA and Amtrak. Trains do not fill at stations that have a problem with their water supply, and passengers and crew would be notified if water testing showed a problem.
Riding the rails this summer? Grab your reusable water bottle and fill up! When it comes to protecting the health of rail passengers, Amtrak is right on track.
