Norlite burned toxic AFFF in greater amounts – and longer – than previously thought, records show
News
23 Mar 2021 | Times Union
Because aqueous film forming foam, or AFFF, is not federally classified as a hazardous waste, there was no requirement that either the shipper – the Department of Defense – nor Norlite had to report its incineration.

Fate and transport of per- and polyfluoroalkyl substances (PFASs) in the vadose zone
Science
23 Mar 2021 | Sci Total Environ
In this review, we critically discuss the current state of the knowledge and aim to interconnect the complex processes that control the fate and transport of PFASs in groundwater.

Characterization of an AFFF impacted freshwater environment using total fluorine, extractable organofluorine and suspect per- and polyfluoroalkyl substance screening analysis
Science
23 Mar 2021 | Chemosphere
A tool was developed to close the organofluorine mass balance and to tentatively identify overlooked PFASs in various water sources.

Sediment quality assessment framework for per- and polyfluoroalkyl substances: results from a preparatory study and REGULATORY IMPLICATIONS
Science
23 Mar 2021 | Integr Environ Assess Manag
PFOS is a suitable indicator of PFAS contamination in sediments from small streams, being the most detected and on average with the highest concentrations among the analyzed PFAS in Switzerland.

Development of a Gestational and Lactational Physiologically Based Pharmacokinetic (PBPK) Model for Perfluorooctane Sulfonate (PFOS) in Rats and Humans and Its Implications in the Derivation of Health-Based Toxicity Values
Science
23 Mar 2021 | Environ Health Perspect
This study provides a quantitative tool to aid risk reevaluation of PFOS, especially in sensitive human subpopulations, and it provides a basis for extrapolating to other PFAS.

Can microbes save us from PFAS?
News
21 Mar 2021 | C&EN
And Alvarez believes in the microbial infallibility hypothesis—that a microbe will find a way to [degrade] even tough compounds like PFAS. “I am certain that it can happen,” he says.

Families urged to join groundbreaking PFAS health studies at Pease Tradeport
News
19 Mar 2021 | NHPR
CDC will keep recruiting until they've tested about 1,000 adults and 350 children. The study is especially looking for participants who had blood tests with the state after the contamination first came to light in 2014 -- but that's not a requirement to participate.
