Deterministic risk assessment of firefighting water additives to terrestrial organisms
Science
12 Jan 2021 | Environ Sci Pollut Res Int
A number of PFAS-free firefighting water additives were found to pose a hazard to terrestrial organisms based on a worst-case exposure scenario of direct application at the greatest recommended application rate for a class A fire (e.g., wood, paper).

Polymer-coated electrode detects PFAS in water
News
25 Nov 2020 | C&EN
Instead of bringing water samples back to the lab for analysis, researchers would like to have a continuous field monitor. ”We knew that electrochemistry potentially would be sensitive and selective enough to detect PFAS, and it’s rather inexpensive,” Dick says.

[Informational Webinar] EPA's Innovative Ways to Destroy PFAS Challenge
Events
23 Nov 2020
EPA is partnering with the other stakeholders, to co-sponsor a technical challenge regarding the destruction of PFAS. The challenge asks solvers to submit detailed plans for a non-thermal way of destroying PFAS in AFFF, while creating the least amount of potentially harmful byproducts with a $50,000 prize.

PFAS: Rules on firefighting foam mired in dispute over definitions
News
28 Oct 2020 | Wisconsin State Journal
Act 101, passed late last year in Wisconsin on a bipartisan vote, restricts the use of PFAS containing foam to emergency situations and testing facilities with “appropriate containment, treatment and disposal measures” without defining those containment, treatment and disposal measures.
