A federal lawsuit has been filed in Montana that may restrain Federal agencies from dispersing fire retardant from aircraft to assisting in the control of fires.

Plaintiffs maintain that fire retardant is ineffective and contributes to accumulation of potentially toxic PFAS chemicals into the environment.

The outcome of the case may also be significant for California that encounters annual wildfires that destroy homes and infrastructure including the Camp Fire of 2018 that obliterated the community of Paradise.
