@farmerman,
farmerman :
that happened to friends of ours some years ago .
by order of the health department they had to move out of the house - this stuff can be pretty toxic .
cement floor was ripped out and repoured .
oil company's insurer had to pay up - after threatened with law suit .
even after some years there is still some lingering smell when the furnace comes on in the fall .
you better read the oil company the RIOT ACT - NOW !
