A top Pentagon official told an audience in Oscoda on Wednesday that another four years of study are needed on the PFAS contamination seeping from the former Wurtsmith Air Force Base.
The industrial chemicals present a threat to human health. They've been used in firefighting foam on U.S. military bases.
John Henderson is an Assistant Secretary of the U.S. Air Force. He says the Pentagon would like to move faster on cleanup efforts, but it has to be careful.
“We continue to study aggressively, as quickly as we can, what the extent of the problem is,” says Henderson. "So when we do get a solution, it’s the right solution. We get it right the first time.”
