Do we have any reason to believe that happened? There’s been training and response plans for this kind of thing going back to the 70s so it seems like that would be a huge scandal.
I’m not saying the EPA is perfect but simply asking whether we have reason to believe that this case was due to measurement choices, or if that was simply made up for the sake of argument.

I think they also dropped the ball on lead in drinking water supplies across the USA. It's another 'regulatory capture' situation, most likely.
