Per- and polyfluoroalkyl substances (PFAS) are a family of chemicals commonly used since the 1950s in carpets, furniture & other fabrics, cooking tools, outdoor clothing, paper products, fire-fighting foams, and numerous industrial applications. Some are now found throughout the world environment in...

Perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (also called perfluorooctane sulfonate, both referred to as PFOS), the most common and best-studied PFAS, have had considerable public attention in recent years, including, most recently, in New Hampshire, Vermont, New York, New Jersey, Minnesota, and Michigan. Concerns have...

Because PFOA and PFOS have been ubiquitous in daily use for decades, wastewater, biosolids, and other residuals (e.g. from recycle paper mills) typically contain low u/kg (ppb) concentrations. In comparison, in the 2000s, PFAS were found in biosolids (most were likely not significantly-industrially-impacted) in concentrations of tens to hundreds of ug/kg (ppb), with a U. S. average of 34...

Because of highly publicized PFAS contamination issues at industrial sites in MI, MN, NH, NY, and VT in 2015 – 2016, scrutiny of PFAS sources has grown in the Northeast and upper Midwest, spilling over onto wastewater and biosolids/residuals as potential “sources” of groundwater (and possibly surface water) contamination.

While there is considerable research regarding some PFAS (e.g. PFOA and PFOS) in the environment and related fate, impacts, and treatments, little is focused on biosolids and residuals. U. S. EPA is just now beginning to consider research on PFAS related to biosolids and residuals land application. NEBRA is developing an initial land application site evaluation research effort in collaboration...

The environmental, social, and economic benefits of recycling biosolids and residuals are large and significant. However, state regulatory overreaction to PFAS concerns could result in reductions in beneficial uses – and just when more efforts are being made to divert more organics from landfills in order to reduce greenhouse gas emissions and utilize the resources in these materials.
