It is no secret. The Infinite Loop campus and the new campus are both on superfund sites. There are signs posted in the lobby ways exiting to the parking lots outside and to the inner campus. I think people are so numbed by seeing Prop 65 warnings on everything, the signs may not even register. We were told the IL campus was a superfund site during the first day of orientation. I have no idea if this is the case for the new campus.
The whole area has numerous superfund sites, all which have buildings constructed on them.
