Penn State Extension will hold another in its virtual Water Cooler Talks April 13 on Per-and Polyfluoroalkyl Substances from Noon to 1:00 p.m.

Widespread usage of products containing perfluoroalkyl substances (PFAS) and their degradation-resistant properties cause them to accumulate in biosolids and persist in treated wastewater effluent.

Therefore, land application of biosolids and wastewater irrigation can inadvertently introduce PFAS into the terrestrial environment.

To investigate the potential impacts of these reuse activities on the occurrence of PFAS in groundwater, we conducted two sampling campaigns: (i) groundwater samples through the Penn State Master Well Owner Network for homeowners within 25 miles of sites with active biosolids application permit; and (ii) at the Living Filter, where Penn State irrigates its treated wastewater.

Here, we will share the data we have collected so far and discuss its implications in the context of proposed PFAS regulations at the state and federal levels.
