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.

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.
