HRGS has fully staffed and equipped offices in Derry, New Hampshire and Fords, New Jersey, allowing rapid response to projects anywhere in the eastern United States and beyond. HRGS specializes in surface and borehole geophysical services for environmental and engineering investigations, geotechnical support services, subsurface utility engineering services (designation and mapping), and non-destructive testing services. Routine geophysical services include ground penetrating radar (GPR), electromagnetic induction (EM31 and EM61), magnetics, seismic refraction/reflection, VLF, high resolution borehole geophysical logging (ATV, OTV, HPFM, and conventional logs), and others.

Since 1984, HRGS has acquired an extensive and diverse expertise, evolved over thousands of projects, in a variety of challenging settings and environments. Today, we deliver the benefit of this collective experience to you in any wilderness or urban setting with equal ease.

HRGS is as well equipped for job sites in restricted access wilderness areas as well as for urban settings. We have a number of off-road vehicles which allow us to access remote site locations, including a 4-wheel drive All Terrain Vehicle (ATV) to navigate the most rugged terrain.

Our work has taken us from busy metro areas like New York City, DC, Boston, Chicago, and beyond to being 'dropped' by helicopter at remote sites giving us the experience to meet the challenges of working in densely populated to extremely remote regions. The entire HRGS field staff has successfully completed the 40-hour OSHA Hazardous Waste Operations Health and Safety Training, allowing us to work at any controlled site.
