"Forever chemicals" found in Iowa fish

Caveat: Researchers from the U.S. Geological Survey, University of Iowa and other institutions tested mostly small whole fish.

• The study was not designed to determine whether the fish were safe to eat.

Yes, but: Iowa researchers say the findings warrant more monitoring.

Zoom in: Central Iowa sites included Camp Creek near Runnells, a Story County drainage site near Ames, Cardinal Creek near Newton and Mud Lake near Jewell.

State of play: No federal or Iowa law requires routine PFAS testing of fish, although monitoring has been recommended, and the EPA says that states should consider testing locally caught fish.

The big picture: Lawmakers have proposed mandatory PFAS testing for sewage sludge, but an Axios review found no similar proposal requiring fish testing.

⬆️ What we're watching: Whether that changes.
