Study in 'Science' finds missing piece of biogeochemical puzzle in aquifersMay 1, 2014

A study published today in Science magazine by researchers from Argonne may dramatically shift our understanding of the complex dance of microbes and minerals that takes place in aquifers deep underground. This dance affects groundwater quality, the fate of contaminants in the ground and the emerging science of carbon sequestration.

Argonne cleans contaminated Kansas site by feeding bacteriaOctober 8, 2010

When cleaning the bathroom, we usually consider bacteria the enemy. However, a new study conducted by environmental scientists at Argonne National Laboratory has demonstrated a way to enlist bacteria in the fight to cleanse some of the country’s most intractably polluted locations.

Argonne bioremediation effort in Kansas is cleaning up contaminantsOctober 1, 2010

Last year, a team of Argonne scientists led by Lorraine LaFreniere injected iron microparticles underneath fields polluted with carbon tetrachloride near Centralia, Kansas. The researchers coated the microparticles with organic material, which served as bait for bacteria that created the conditions necessary to safely convert the toxic chemical into non-hazardous substances.

Argonne researchers show impact of soil vegetation and moisture on carbon recoverySeptember 1, 2010

Argonne National Laboratory Biosciences Division ecologist Julie Jastrow and colleagues recently published work showing the impact of soil vegetation and moisture on terrestrial carbon recovery. Revitalization of degraded landscapes may provide sinks for rising atmospheric CO2, especially in restored grasslands.

Scientists discover how the structure of plutonium nanocluster contaminants increases risk of spreadingApril 22, 2008

For almost half a century, scientists have struggled with plutonium contamination spreading further in groundwater than expected, increasing the risk of sickness in humans and animals.
