ALBUQUERQUE (AP) — Results of preliminary tests on Albuquerque's water supply suggest the Air Force may have found the edge of a plume of contaminated groundwater spreading outward from a decades-old jet fuel spill at Kirtland Air Force Base.

Jim Davis, head of the New Mexico Environment Department's Resource Protection Division, told The Albuquerque Journal that water drawn from new wells beneath a southeast Albuquerque neighborhood that's midway between the contamination and the nearest municipal drinking wells appears to be clean of contamination.

Davis said the new test results mean the current risk to drinking water is small.

Officials are awaiting confirmation of the results.
