No harmful levels of carcinogenic PCBs were found inside the missile launch facilities at F.E. Warren Air Force base in Wyoming, the service said Tuesday, as it looks for possible causes for cancers being reported among its nuclear missile community.
F.E. Warren is among three nuclear bases the Air Force is investigating. Earlier this month the Air Force reported it had found harmful levels of PCBs at two locations at Malmstrom Air Force Base in Montana. Results from Minot Air Force Base in North Dakota are pending, as are water quality tests from each of the locations.
