“So this is trading one hazardous waste stream for another,” said Alaska Community Action on Toxics' Pam Miller, criticizing plans to clean one of 16 sites at Eielson Air Force base contaminated by PFAS firefighting foams.
And a longtime Alaska contamination expert is skeptical of the PFAS-cleanup technique that’ll be used at Eielson.
Miller says soil-washing lacks enough real-world testing to ensure it’ll work as well as its advocates claim. And she says there’s a lack of transparency on whether the process will clean the soil enough to be safe for uses such as backfill, as required by the contract. But Miller says some of the more than 12,000 chemical compounds — collectively referred to as PFAS, or per- and polyfluoroalkyl substances — will get through the filter. And she says the contaminated filters would then create another disposal problem.
“This class of chemicals, the PFAS chemicals, are virtually unregulated at this point,” she said. “There are not health-protective standards for drinking water, for soil cleanup.”
