Are you suggesting they buried polluted dirt in the launch pad to distribute later? It's just like construction dust. It's unpleasant and inconsiderate but it's not highly toxic or a pollutant.

I mean the concrete dust that got airborne as it was being blown apart. It's airborne silica and is toxic which is why construction workers wear masks when producing it.
