Company Overview

Blackhawk GeoServices provides a broad spectrum of high-resolution subsurface imaging and UXO services in support of a wide variety of environmental remediation activities. Specifically, for remediation of UXO (Unexploded Ordnance) contaminants, Blackhawk UXO (a division of Blackhawk GeoServices) specializes in UXO detection surveys and UXO remediation services for clients worldwide.

Uniques aspects of Blackhawk GeoServices qualifications for subsurface environmental site characterizations and remediation monitoring are:

  • The company provides geophysical contracting and consulting services over the full spectrum of geophysical technologies.  This is important for the reasons that the application of any geophysical technology is site specific, and often requires the use of complimentary methods to improve reliability and accuracy of interpretation.
  • In addition to performing some 50 geophysical projects annually, the company also has an active Research & Development (R&D) program to improve the state-of-the-art of near surface geophysics.  The results of several R&D programs are presently being introduced into engineering practice.
  • The technical staff of Blackhawk consists of highly qualified and experienced field personnel, as well as R&D staff, so that innovative approaches to complex problems can be commercially used.

Unique aspects of Blackhawk s qualifications in UXO geophysics (detection) and remediation services are:

  • Blackhawk is the exclusive commercial provider for the Multi-sensor Towed Array Detection System (MTADS).  Acquired through a CRADA (Cooperative Research and Development Agreement) with the Naval Research Laboratory, the MTADS is a proven, complete hardware and software detection system which was developed specifically to detect and locate buried UXO (Unexploded Ordnance).
  • Blackhawk has an excellent resident staff of geophysical professionals, trained and experienced in detecting and locating UXO using a variety of geophysical methods including time-domain electromagnetic (TDEM), total field magnetometer (MAG), airborne magnetometer and underwater magenetometer, and electromagnetic (EM).
  • Blackhawk has an excellent resident staff of UXO professionals, trained at the prestigious U.S. Naval School, Explosive Ordnance Disposal, Indian Head, Maryland and seasoned by years of active duty military EOD and commercial UXO experience.
  • In addition to performing some 50 UXO geophysical projects annually, the company also has an active R&D  program to improve the state-of-the-art of near surface geophysics. Well over 50% of the R&D contracts are directed toward developing sensors and software directly in support of UXO and de-mining.
  • Blackhawk has both specialized UXO geophysics capabilities and UXO removal capabilities in-house.
  • Blackhawk UXO is the industry leader in providing integrated UXO geophysics and UXO support services.
  • Blackhawk applies innovative technology solutions to the complex problems associated with UXO detection, location, removal, and disposal.
  • The technical staff are among the most qualified in the industry.  Experienced field personnel are backed up by highly qualified R&D personnel.
