NASA faces at least $1.9 billion in environmental clean up and restoration costs at its far-flung network of centers, an amount that has increased $724 million, or 61 percent, since 2014, according to a new Government Accountability Office (GAO) report.

While five of 14 centers where chemical contamination exists have decreased their cleanup liability, other centers such as Kennedy Space Center, Ames Research Center and the White Sands Test Facilities have seen increased costs from 2014 to 2019.
