Geophysical Technology

The Geophysical Technology Department develops and implements geophysical techniques for investigating the earth's subsurface. We concentrate on solving problems important to the Department of Energy in areas of fossil energy, hazardous and nuclear waste management and restoration, defense, nonproliferation, and energy-related basic research. The department staff has a broad range of expertise in seismology, electromagnetics, petroleum and sedimentary geology, thermal geophysics, and mechanical and electrical engineering. This breadth enables us to attack a wide variety of problems ranging from algorithm development and computer modeling, technology design and bench-scale experimentation, to field experiments, data collection, processing, and interpretation. Leading-edge geophysical instrumentation development, often with industrial partners and particularly for borehole applications, is an important focus for the department; another major area is seismic and electromagnetic data modeling and inversion.

Environmental Restoration Technology

The Environmental Restoration Technology Department provides customers with innovative solutions to problems created by environmental hazards at contaminated sites. To meet customer needs, solutions range from components drawn from our lab-wide scientific competency base to complete systems based on our systems engineering experience. We actively seek partnerships with stakeholders who impact usage and commercial suppliers who will deliver services to those markets. Our lines of business include:

Environmental Restoration Technology Development

Our technology development and deployment staff are experienced in moving innovative ideas from the basic/applied research stage to application. We have current projects in the following areas:

  • Characterization: Our technology ranges from individual sensors to complete systems providing information about a site including the source, type, mobility, amounts, and spatial distribution of contaminants. Our efforts in this area have resulted in the receipt of R&D 100 awards in past years.
  • Remediation: We specialize in the development of innovative remediation technologies which can minimize risks posed by contaminated sites without excavating the waste materials and soils (e.g., in-situ treatments).
  • Containment: Our technology portfolio provides tools that can be used to isolate contaminants while natural or man-made remediation processes completely eliminate the source, or can be used to prevent further migration until remediation can be performed at a later time. We have extensive experience in surface and subsurface, permeable and impermeable, innovative barrier/containment technologies.
  • Monitoring: Monitoring follows remediation and/or the installation of containment barriers to verify that contamination has been removed or contained as intended. We develop innovative monitoring technologies to more cost-effectively meet this long-term need.
Environmental Restoration Field Operations (ERFO)

We perform environmental field operations. Our ERFO Team provides equipment, technical guidance, and field support to cleanup operations for the environmental restoration project at Sandia and to technology development field tests/demonstrations at sites across the United States. We perform groundwater and site assessments, soil and soil gas sampling, earth moving, site restoration actions, data acquisition, and monitoring activities.

Environmental Restoration Synergistic Activities

We also perform work that is synergistic with our environmental restoration projects. For example, our staff support the development and maintenance of the technology management information system used by the DOE's Environmental Management Office of Science and Technology. This provides a service to our primary customer and provides a better understanding to us of the needs for new technology. We also contribute in a major way to the DoD effort for improvements in environmental fate and transports modeling required to better define chemical signatures emanating from buried landmines and unexploded ordinance. This broadens our knowledge on the movement of a wide variety of environmental contaminants.

Environmental Restoration Operations

Environmental Resoration (ER) project activites include cleanup and remediation of a hazardous waste landfills, and investigative work leading to closure. Since the project's inception in 1990, ER staff have identified about 240 potentially hazardous sites in New Mexico and elsewhere. To date, we have cleaned up and/or proposed 200 sites for no further action (NFA). Sites proposed for NFA were identified as having essentially no risk to human health of the environment through administrative record searches, site assessment, and risk analysis procedures.

ER staff routinely team with private industry for help in completing assessment and remedial actions. The ER staff also established a chemistry laboratory for performing rapid, quality analysis of volatile organic compounds, metals, high explosives, nitrate, anions, and laboratory hydrologic properties.
