What HRGS does

HRGS (Hager-Richter Geoscience, Inc.) is a privately held geophysical consulting firm founded in 1984 and headquartered in Derry, New Hampshire with a second office in Fords, New Jersey. The firm provides surface and borehole geophysical services — including ground penetrating radar (GPR), electrical resistivity imaging, electromagnetic induction, magnetics, VLF, microgravity, surface seismic (refraction, reflection, MASW), borehole seismic, borehole geophysical logging (optical/acoustic televiewer, NMR, full waveform sonic), precision utility locating, and vibration monitoring — to engineering and environmental consulting firms, government agencies (including the National Park Service), construction companies, and archaeological organizations. HRGS owns its geophysical equipment outright (including cesium vapor magnetometers, a full GPR antenna suite, and a custom solar/battery-powered logging van), enabling rapid mobilization across the United States without rental-schedule dependencies. The firm employs approximately 26 staff including senior geophysicists, geophysicists, technicians, and administrative personnel, with Professional Geologists licensed in New Hampshire, New York, Pennsylvania, Louisiana, California, and Wyoming. In 2024, Jeffrey Reid and Robert Garfield transitioned from vice president roles to owners of the company.

HRGS operates as a specialty subconsultant, typically engaged by primary engineering or environmental consultants rather than contracting directly with end clients, with services billed on a per-project professional services basis. The firm has executed thousands of projects across 45 U.S. states plus the District of Columbia and internationally in Canada, the Caribbean, Europe, Central America, and Asia. GTM is primarily relationship-driven through direct field sales, supported by industry conference presentations (NYSCPG Geology Days 2024, Highway Geology Symposium 2024, CNYAPG Field Days), periodic newsletters, and professional association participation. Revenue is not publicly disclosed; the company has no disclosed funding rounds, no parent company, no active social media presence, and no recorded M&A or partnership activity in the input data.

Broad incumbents

• AECOM: AECOM is a global infrastructure consulting firm with extensive geotechnical, environmental, and subsurface investigation capabilities that overlap with HRGS's service lines. As an incumbent, AECOM competes for and often leads large projects where HRGS would serve as a subconsultant.
• Terracon: Terracon is a national geotechnical, environmental, and materials consulting firm that performs subsurface investigations for engineering and construction clients across the US. Its broad footprint and integrated offering position it as a broader incumbent competitor that can either compete with or pull through HRGS-style specialty geophysics.
• Tetra Tech: Tetra Tech is a large multi-discipline consulting and engineering firm with a deep environmental and geotechnical practice that often internalizes geophysical services otherwise outsourced to specialty firms like HRGS. Its scale and integration represent both competitive pressure and a potential upstream pipeline for HRGS-style subconsulting engagements.

Direct peers

• GeoEngineers: GeoEngineers is an integrated geotechnical, environmental, and geological consulting firm serving infrastructure, water resources, and energy clients. Like HRGS, it acts as a specialty subconsultant applying surface and subsurface investigation methods to engineering projects.
• Zonge International: Zonge International provides geophysical consulting services using electrical, electromagnetic, seismic, and magneto-telluric methods for engineering, environmental, and exploration applications. It is a specialty geophysics firm with similar toolset and subconsultant-style service delivery to HRGS.
• Haley & Aldrich: Haley & Aldrich is a geotechnical and environmental consulting firm providing subsurface investigation services to engineering and construction clients, directly comparable to HRGS in the engineering/environmental subconsultant role. The firm offers similar subsurface characterization, environmental site assessment, and remediation support services.
• Schnabel Engineering: Schnabel Engineering is a specialty geotechnical and dam engineering consulting firm offering subsurface characterization, including geophysics, similar to HRGS. Both firms serve engineering and environmental clients with non-invasive site investigation services and operate as specialty subconsultants within larger project teams.
• Northwest Geophysical Associates: NGA is a specialty geophysical consulting firm providing surface seismic, GPR, magnetics, and resistivity surveys for engineering, environmental, and groundwater applications. Its services, client base, and project-based professional services model closely parallel HRGS.
• Olson Engineering: Olson Engineering is a specialty geophysical and structural instrumentation firm focused on non-destructive testing, seismic, and borehole methods for infrastructure and dam safety projects. The firm's borehole and seismic services directly overlap with HRGS's specialization.

Emerging players

• Geometrics: Geometrics designs and manufactures geophysical instruments (magnetometers, GPR, seismographs) and offers contract survey services, making it both a vendor and a partial peer to HRGS. Its service arm uses similar surface geophysical methods for engineering and environmental projects.
