It has come to our attention that we inaccurately described recent water treatment changes and associated costs in North Carolina. Following extensive contamination by a PFAS manufacturer in the Cape Fear River watershed, Brunswick County, North Carolina is spending $167.3 million on a reverse osmosis plant1 and the Cape Fear Public Utility Authority spent $46 million on granular activated carbon filters (not $99 million as we originally reported), with recurring annual costs of $2.9 million.2 We regret the error. This does not change the conclusions or arguments of our paper.
