Department Description:

The Geochemistry Department has expertise in three areas: 1) molecular-scale modeling, 2) experimental geochemistry, and 3) applied environmental/chemical engineering. We tackle geosciences-related problems with an application for carbon sequestration, unconventional oil and gas recovery, nuclear waste management, and environmental remediation. In addition, we reach beyond the subsurface environment looking at nuclear weapons applications and air-borne contaminant detection and removal. Program focus is currently on chemical effects on fracture initiation and propagation, heterogeneous redox chemistry on clay mineral surfaces, coupled geochemistry and geomechanics in shales, and permeable reactive barriers for soil radionuclide remediation. Computing facilities for molecular modeling include a cluster (CPU nodes, GPU nodes) maintained by the Geochemistry Department as well as the Sandia High Performance Computing. In addition, we have 3,000 square feet of laboratory space that includes the following analytical equipment: XRD, FTIR, ICP-MS, ICP-OES, TOF-MS, and SEM.

Security Clearance:

This position does not currently require a Department of Energy (DOE) security clearance. Sandia will conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Furthermore, employees in New Mexico need to pass a U.S. Air Force background screen for access to Kirtland Air Force Base. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause access to be denied or terminated, resulting in the inability to perform the duties assigned and subsequent termination of employment. If hired without a clearance and it subsequently becomes necessary to obtain and maintain one for the position, or you bid on positions that require a clearance, a pre-processing background review may be conducted prior to a required federal background investigation. Applicants for a DOE security clearance need to be U.S. citizens. If you hold more than one citizenship (i.e., of the U.S. and another country), your ability to obtain a security clearance may be impacted. Members of the workforce (MOWs) hired at Sandia who require uncleared access for greater than 179 days during their employment, are required to go through the Uncleared Personal Identity Verification (UPIV) process. Access includes physical and/or cyber (logical) access, as well as remote access to any NNSA information technology (IT) systems. UPIV requirements are not applicable to individuals who require a DOE personnel security clearance for the performance of their SNL employment or to foreign nationals. The UPIV process will include the completion of a USAccess Enrollment, SF-85 (Questionnaire for Non-Sensitive Positions) and OF-306 (Declaration of for Federal Employment). An unfavorable UPIV determination will result in immediate retrieval of the SNL issued badge, removal of cyber (logical) access and/or removal from SNL subcontract. All MOWs may appeal the unfavorable UPIV determination to DOE/NNSA immediately. If the appeal is unsuccessful, the MOW may try to go through the UPIV process one year after the decision date.
