Awhile ago in Huizen we were doing a post-sanitation check up at the location, and as it turns out the contractor didn't cross all his T's.
While taking some soil samples I came across a weird colored ground, it's official name is Berlin Blue and it is a form of cyanide. So I ended up finding a 1 1/2 foot thick layer of this stuff and according to our expert it can be quite deadly.
So naturally I needed to take a sample and while I was at it a nice photo.
ENJOY.
