Meeting or Teleconference Held |
DEC met with Chevron and ARCADIS to discuss several Fairbanks area sites. Recent investigations suggest that the "western plume" may have a different source than the petroleum plume on this site or the other two adjacent sites, however it is unclear what that source may be.
