SubsurfacePNNLNews

Subsurface@PNNL takes research underground, providing an in-depth understanding of natural and engineered subsurface systems. Its “science-to-solutions” approach can be applied to improve the way subsurface contaminants are remediated and isolated, legacy waste is stored and disposed of, and energy sources are accessed and extracted.

Portrait of Mike Truex

Our integrated, interdisciplinary approach to environmental remediation results in a diversity of success stories that cross multiple areas of technical expertise. See our publications page for a selection of journal articles and reports.

PNNL's computational geophysicists developed the Real-Time Four-Dimensional Subsurface Imaging technology to remotely and automatically sense large areas of the subsurface, allowing environmental remediation experts to ‘see’ contamination that is so deep it’s impractical to dig up.
PNNL’s integrated experimental and modeling approach generates critical, location-specific information about how to approach subsurface contamination and meet environmental remediation objectives at Hanford and other complex sites.
