Watchdog group reports ‘extreme contamination’ of plutonium at Los Alamos open space

The legacy of environmental waste is “hiding in plain sight” at a popular open space in the heart of Los Alamos that became a dumping ground during the Manhattan Project, according to testing results a nuclear watchdog group released Thursday.

Soil, plant and water samples collected in July from Acid Canyon — yes, Acid Canyon — revealed “extreme contamination,” including detections of what Nuclear Watch New Mexico said is some of the earliest plutonium produced by humankind.

“What I found here in Acid Canyon [is] pretty much the most extreme contamination scenario I’ve seen in an off-site, uncontrolled environmental setting,” Michael Ketterer, a professor emeritus of chemistry and biochemistry at Northern Arizona University, said during a virtual briefing.

Ketterer, who collected the samples in July with the help of the watchdog group, said he’s analyzed tens of thousands of plutonium samples in a decadeslong career.

“This is way, way, way, way, way at the top end of the charts in terms of how much,” he said. “This is extreme contamination.”

Ketterer said he would compare it to “Chernobyl proximity samples” and samples close to Palomares, Spain, after a B-52 bomber carrying hydrogen bombs collided with a refueling plane in 1966 and coated the seaside town in radioactive dust.

“Hundreds of samples from near Rocky Flats do not come close at all,” he said, referring to a former nuclear weapons production facility in Colorado.
