By 2001, the U.S. military knew firefighting foams used at bases across the country could break down into toxic chemicals, that the chemicals had entered streams and groundwater at several military bases, and that they could potentially be polluting drinking water wells.
But despite one Department of Defense employee’s prediction that phasing out the foams could be an environmental task rivaling the magnitude of asbestos removal, the military continued to use the foams — without investigating whether anyone on or off the bases had been sickened, according to military records and emails.
