Environmental engineering firm Brown and Caldwell (Walnut Creek, Calif.) has been granted funding from The Water Research Foundation (WRF) to study the fate of per- and polyfluoroalkyl substances (PFAS) through sewage sludge incineration.
Thermal treatment of PFAS-laden wastewater solids through sewage sludge incinerators (SSIs) offers a potential PFAS control strategy; however, with few published research studies available, the ability of SSIs to fully mineralize PFAS is unknown.

To this end, a research team led by co-principal investigators Lloyd Winchell (Brown and Caldwell) and Dr. Detlef Knappe (North Carolina State University) has been awarded a $100,000 grant from WRF through its Tailored Collaboration Program to support utility-specific/regional issues. The study aims to explain the fate of PFAS compounds through SSIs and provide utilities with an indication of the extent to which SSIs can eliminate or r
