“Maybe we are done at a lot of these sites, but we just don’t know how to say that,” said Steven Cook, a Trump administration appointee.

The Trump administration’s top official in EPA’s land office is focused on expediting Superfund hazardous waste remediation, in part by loosening cleanup standards.

That involves state leaders, retraining project managers and rethinking acceptable cleanup levels for dangerous chemicals at Superfund sites, Cook said.
