Trump promises to veto a bill banning the military from using toxic products with PFAS
News
11 Jul 2019 | Pacific Standard
US President Donald Trump threatened to veto a defense spending bill with an amendment that restricts the use of a toxic chemical compound found in firefighting foams. Several provisions in the bill, introduced in the House of Representatives, would require the United States Department of Defense to switch to safer foams without PFAS... The bill would also require the military to pay to clean up sites where its activities have contaminated the water, including farms and watersheds, and classify the areas as Superfund sites.
