It seems that not even the US of A has been able to solve this issue and that only using it as a cement substitute and as a base for roadways (which are then covered with an impermeable layer) are safe ways to get rid of the stuff.
The issue here is, that nobody really knows what has happened with the stuff dumped in Samaná or Manzanillo. It was reported that Pemex was trucking it away from the Samaná site, allegedly to "burn it" but I would venture to say that whoever wrote the story did not actually see the whole thing through. Most probably it was used as a substitute of cement, which seems to work.
Anyway, no studies have been carried out as to just how badly the dry fly ash affected people in the areas nearby...something that certainly should be done.
With warm greetings for a New Year,
