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.

Well water throughout California contaminated with ‘forever chemicals’
News
19 Nov 2020 | CALmatters
Californians are largely left in the dark about the safety of their drinking water: Less than 9% of roughly 14,350 public drinking water wells in the state have been tested for PFOA and PFOS. State requirements have focused on areas considered vulnerable to contamination, such as near airports and landfills.
