“It is thought that the shorter chain PFOAs are less toxic,” Cannon said. “But I would say we truly don’t know that. The data is not there. We have all these alternatives in the environment with little to no toxicity testing. In some cases that may be true. They may metabolize and leave the body faster, but from a neurological standpoint the smaller compounds usually penetrate the brain better. So that is something we need to pay attention to.”

PFAS Regulations: How We Got Here and How to Recover the Costs
Science
3 Feb 2020 | J. New England Water Works Ass.
Legal precedence has been set for recovering the costs of cleaning up contaminated drinking water and for shifting treatment costs from ratepayers to polluters. Under the theory of product liability, manufacturers of chemicals responsible for contamination are held accountable for the associated treatment costs.
