$10B? Lol. Minnesota alone estimates it will need $14-28B:

Multiply that by 50 for all states. Use a fudge factor if the $14-28B range seems like too big of a horse pill to swallow. If it brings you solace, pretend US territories don’t exist (https://legalnewsline.com/stories/523080135-guam-files-pfas-lawsuit-against-3m). Travel aboard Mr. Roger’s trolly to the Neighborhood of Make Believe where 3M the highly regarded PFAS shepherd successfully whines and convinces the EPA not list PFOS and PFOA as Superfund chemicals (https://pfas.3m.com/Proposed_CERCLA_Designation). And enjoy your recently legalized re---r.
It makes no difference really. No matter what MoPo-style financial engineering you try (even exquisitely packaged in a PowerPoint presentation) you wind up at a mind boggling number that still doesn’t include any property damage, personal injury claims. Or anything outside the US, where entire countries are looking for their due. (https://www.reuters.com/business/environment/dutch-government-hold-3m-liable-forever-chemicals-damage-2023-05-23/).
Earplugs are a fa-t in a hurricane in comparison to PFAS.
The end is nigh.
