No one knows if it came from Kirltland or not. They're still drilling test wells and have yet to determine the source. Davis implied only dry cleaners use that solvent but he is wrong. It's commonly used as a metal degreaser for aircraft parts. The AF does use it.
The Environment Department announced last month that the potentially cancer-causing chemical perchloroethylene, or PCE, had been discovered in test wells being drilled to monitor nearby contamination from an old Kirtland Air Force Base aviation fuel spill.
The PCE appeared to be unrelated to the Kirtland spill, and set officials off on a search for an old dry cleaner or similar site that might have caused a leak.
But follow-up testing, done over the past three weeks, found no signs of PCE contamination, according to Jim Davis, head of the New Mexico Environment’s Resource Protection Division.
The most likely explanation is that the contamination came not from groundwater, but from equipment being used to collect the initial samples, Davis told members of the Albuquerque Bernalillo County Water Utility Authority on Wednesday evening.
