[Press release] Department of defense illegally burning stockpiles of toxic “forever chemicals”
News
20 Feb 2020 | EarthJustice
The Department of Defense sued over its contracts to burn millions of gallons of unused firefighting foam containing PFAS in incinerators across the country. PFAS resist incineration and do not break down under temperatures and conditions that are sufficient to destroy other toxic chemicals. Incomplete incineration may result in PFAS emissions, as well as other toxic chemicals like hydrogen fluoride, which is poisonous, corrosive and flammable.
