Building 143 was built in 1992, and in 1982.... I have talked to some retired members who caught hold of other people who had seen environmental...doing sampling around that area.
Yes, we don't know what PFOS is, but we also know that in that area, they had fuel to start the fires. It's the hydrocarbons. Yes, PFOS is just as big, but I'm going to tell you that the DND is going to tell you about PFOS.
I'm sorry.
