Has anyone on list had experience of contractors decontaminating land?

No personal experience, but as a matter of interest;

My mate worked in a small factory unit next to the old Vickers Armament
factory in Crayford, Kent, which was about to be demolished, having been
empty for years.

He became chatty with the site foreman. A few days after they started
demolition, they stopped work. It had suddenly occured to them that there
was no sound or movement in the dissused building, no rats, no birds etc.

Turned out to be knee deep in heavy metals or something of that ilk.
Whatever it was, they stopped work immediately & the decontaminating people
moved in. Took about 6 months apparently, cost the developer a fortune.
Now a business park c/w McDonalds.

No change of use though ;-)
