Cleaning up Hanford is no easy task: it is one of the world's largest and most complex environmental remediation projects. The nation's top engineering firms are on the job and the Department of Energy's PNNL is helping.

Just reading the headlines makes it clear that these are anxious times.

New approach to monitoring sequestered carbon dioxide movement to be presented at AGU.

Oil spills could be cleaned up in the icy, rough waters of the Arctic with a chemically modified sawdust material that absorbs up to five times its weight in oil and stays afloat for at least four months.

PNNL is supporting today's announcement by the White House about efforts related to soil sustainability by sponsoring research projects through two research initiatives.

PNNL tools that track underground contaminants and speed carbon capture technology development are among R&D Magazine's 100 most innovative scientific breakthroughs of the year.

PNNL takes pride in advancing scientific frontiers and developing solutions to vexing problems. In particular, we apply our technical expertise to address national needs in security, energy and the environment.

Calcium carbonate found in chalk, shells and rocks is one of the most important materials on earth. New insights on how it turns into hard, strong materials will help scientists design materials needed for a low-carbon future.

Nuisance alarm rates in radiation detectors at seaports and ports of entry are down significantly due to PNNL data analysis efforts that are saving time and money at the ports.
