Excavation to the west <br /> was stopped, even though there was a small amount of <br /> ,"=' contamination remaining, because 35' of overburden had to be <br /> removed to continue. <br /> -� Sade unknown amnunt of- contamination remains under- rthe <br /> building'= and` c"n" slab' to_:_,the south., The­aaauYA ands: <br /> netraton ,ia unk <br /> pe nown Thi OyA meter;:reading exceeded 14�OF�p! <br /> TPf�` starpin <br /> g.: at about Z2'. .deep to 30' Aeep The _ varit systp <br /> should,;rec edy,.thie;'nrea, <br /> The backfilling of the hole should be completed in .January <br /> or February 1988.
