The company does deep well injection for toxic water disposal. They claim thousands of feet down, below any water table. Would take a thousand years to come back up blah blah. The whole business model is like that episode of Futurama where earth launches its trash into space and it comes back hundreds of years later.

Edit: You know what, this libertarian, corporatist hellscape is what Texans voted for. I support all manner of toxic and radioactive waste, PFAS, heavy metals and such being disposed of by deep well injection under Texas.
