Waging war—and keeping the peace—can be a dirty business. On this episode of Parts Per Billion, we speak with Rep. John Garamendi (D-Calif.), the congressman in charge of the Pentagon's environmental cleanup, about how the military is doing on this difficult issue and about negotiations over what could be a landmark bill to address PFAS contamination.
