Any Environmental Watchdogs here?

[Amarok]

I would imagine the nature and location would determine the government department 

Is it ?
Radio Active 
Biological 
Chemical 
Or even a natural phenomenon 

Who's land is it ?


Who or what caused whatever it is to be there ?
Military project 
Industry  

Any details on the kind of suits they were using ?

And trees you say that's very interesting so it's lethal enough to kill plant life or cause ground sterilization
