What wwaswas says regarding not being able to sell and you do realise the remediation/cleanup will have been done by the lowest bidder.
The cynic in me says that the approved testing will have been at certain cleaned to standard spots with a more laissez faire attitude across the rest of the site and there is also the possibility of a nice holiday/watch/car/envelope stuffed with notes for somebody if “performance” targets are met on budget or certain reports are editted.
Oh and I love experts, after we had complained about the state of the transformers at an underground site we used to have, the state run organisation called in an expert to analyse and tell us it was safe to clear up with minimal PPE (this was back in the early 90’s). The after meeting questions went like this
Expert, “yes that transformer oil is perfectly safe to clean up with rags”,
My colleague “well then, you’d be happy to do it with us ?”
Expert “err that’s a bit of a leading question”
