Organic matter found in vast quantities in oxygen-starved floodplains would yield only minimal energy for hungry microorganisms, which spurn the meal, researchers show in a study in Nature Geoscience.

Like detectives looking for clues, researchers at the Department of Energy's Pacific Northwest National Laboratory have been working for nearly a decade on ways to identify the "fingerprints" of potential chemical threats.

PNNL scientists recently gave a crash course on soil to young children at a local elementary school, dishing up the dirt on soil.

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.

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

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.
