Technology Focus 

• Develop coupled in situ remediation technologies to treat groundwater plumes containing mixtures of per and polyfluoroalkyl substances (PFAS) and chlorinated ethenes. 

Research Objectives 

• Develop highly sorptive and reactive nanomaterials for PFAS and chlorinated ethenes; Develop biological systems to degrade chlorinated ethenes and PFAS byproducts; Evaluate the performance of coupled physicochemical and biological technologies in dynamic systems. 

Project Progress and Results 

• Synthesized highly sorptive nanomaterials; Demonstrated heated activated persulfate degradation of PFOA; Detected inhibition of TCE and PCE degradation in the presence of PFAS mixtures; Demonstrated sequestration of PFOA and PFOS in columns treated with stabilized activated carbon. 

Technology Transition 

• Continue nanomaterial synthesis and treatability testing; Disseminate findings via publications, conference, and professional organizations.
