The school is one of the largest atmospheric and environmental academic research centers in Britain. Pearce, who came to the Laboratory in 2009, is investigating how minerals and microbes affect technetium and other radionuclides in the soil at a former plutonium production site in southeastern Washington State.

Unique Uranium Source in Naturally Bioreduced Sediment

November 2009
Results: A recently published Pacific Northwest National Laboratory study of a naturally bioreduced sediment sample from a former uranium mill tailings site reveals insights that enhance understanding of the long-term persistence of uranium in groundwater. The study provides the first-ever evidence of a useful pyrite mineral formation within the sample.
