U.S. EPA releases PFAS risk assessment: Now what?
from Talking Under Water · host Endeavor Business Media
In April of 2022, Maine banned land application of biosolids due to concerns of PFAS. It has become a point of contention in the state, causing wastewater systems to scramble for alternatives with much of it going over the border to Canadian landfills as Maine landfills refuse to accept the waste or run into capacity issues. Nearly two years later, U.S. EPA released a long-awaited risk assessment of two PFAS chemicals — PFOA and PFOS — in sewage sludge and land-applied biosolids on January 14, 2025. While this assessment is not a regulation, it suggests a degree of risk that could one day include a regulation. So what do wastewater leaders need to do now and what does this assessment mean for them? Endeavor Business Media Water Group Editor Alex Cossin caught up with Kyle Thompson, the PFAS national practice lead for Carollo Engineers, to get the details.
