Geophysics Services for Subsurface Investigation & Risk Mitigation

Encountering unknown subsurface conditions can be costly for your project, both in money spent and time lost. ARM Geophysics has the in-house knowledge and equipment to help you avoid the unexpected and to provide unique insights into the earth’s subsurface. 


Our Geophysics Services:

  • Surface Geophysics

    Surface geophysical methods provide non-invasive insight into subsurface conditions, supporting site characterization, infrastructure planning, and environmental investigations.

    • A critical first step in property transactions, Phase I ESAs evaluate historical and current site conditions to identify potential environmental liabilities.
    • Review of historical land use and environmental records
    • Site reconnaissance and regulatory agency database reviews
    • Identification of recognized environmental conditions (RECs)
    • ASTM-compliant reporting

  • Borhole Geophsyics

    Borehole geophysical logging enhances subsurface data collection and interpretation by providing continuous, in-situ measurements within wells or boreholes.

    • If potential environmental concerns are identified in Phase I ESA, Phase II ESA involves sampling and laboratory analysis to determine contamination levels.
    • Soil, groundwater, and surface water sampling
    • Indoor air and vapor intrusion assessments
    • Risk-based corrective action recommendations
    • Regulatory compliance coordination

  • Munition Response Surveys

    Munition response surveys are essential for identifying and addressing potential hazards related to unexploded ordnance (UXO) and munitions-related debris on current or former military and training sites.

    • Site investigation and clearance for UXO and munitions debris
    • Advanced digital geophysical mapping (DGM) and anomaly detection
    • Target characterization and discrimination analysis
    • Remedial investigation and support for risk-based decision making
    • Compliance with Military Munitions Response Program (MMRP) standards
