The Deep Vadose Zone program leads a treatability study for subsurface remediation of the Hanford Site’s Central Plateau.

Researchers are developing and deploying solutions to reduce risk and increase efficiency while keeping people and the environment safe.

PNNL’s Center for the Remediation of Complex Sites convened attendees from around the world to discuss challenges associated with environmental contamination.

Scientists at PNNL have published a new article that focuses on understanding the composition, dynamics, and deployment of beneficial soil microbiomes to get the most out of soil.

PNNL chemists investigate the performance of ion exchange resins for subsurface remediation of uranium, technetium, and chromium.

STEM Education programs at DOE and national labs offer environmental management internships; applications are due soon for summer 2023.

A new web-based tool provides easy-to-understand progress metrics and other data about groundwater cleanup sites overseen by the DOE Office of Environmental Management.

PNNL scientists have proposed an "adaptive site management" cleanup strategy for the Hanford Site's Central Plateau that incorporates a structured, flexible approach to environmental remediation.

Tomorrow’s scientific leaders gain real-world experience contributing to PNNL’s research and development.

Understanding the Earth as a complex, dynamic system includes investigating what happens on, above and below its surface.

Peering through the thick, green glass of a decades-old "hot cell," an expert technician manipulates robotic arms to study highly radioactive waste from Hanford, in support of ongoing cleanup.

This time of year finds many of us busy with holiday shopping. While PNNL might not be developing the latest video games or hoverboards, we are working hard to deliver a few presents you might like.

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.

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.
