My guess, with a certain US Political Party cutting funding for things like the EPA and Super Fund Activities, I would guess no one had the funds to properly diagnose and do the appropriate cleanup. So they decided it was good enough for "now" until this was discovered. I would say the Company that caused the spill will get away without paying cleanup costs. That is what usually happens with these type of Environmental Damage in the US.
