Challenge Testing is proud to announce the official opening of our newest location in Guam, further strengthening our presence in the Pacific region. This expansion marks a major milestone for our company as we continue to grow and support the infrastructure, environmental, and development needs of communities across the Marianas.

Why Guam?

With decades of experience across the Southeast U.S., Caribbean, and Saipan, establishing a permanent presence in Guam is a natural step forward. Guam represents a strategic location for continued growth and deeper support of military, commercial, and local development projects that require expert geotechnical services, non-destructive testing (NDT), and drilling capabilities.

Our team has already been active in the region through key water well drilling and support work on nearby Saipan, providing vital access to clean water resources. The significance of this work cannot be overstated, especially in remote island environments where access to fresh water is critical for community health, agricultural use, and development. With the Guam office now fully operational, we are expanding our capabilities to bring the same quality and reliability to a broader range of clients across the Marianas.

Our Services in Guam

The Guam office will offer a full range of Challenge Testing’s core services, including:

  • Geotechnical Drilling & Sampling
  • Environmental Drilling
  • Water Well Drilling
  • Non-Destructive Testing (Radiographic, UT, PT, MT)

Looking Ahead

We’re excited to grow our team locally, partner with regional clients, and continue bringing reliable data and safe, efficient drilling and testing services to Guam and beyond. Whether it’s supporting new infrastructure, improving environmental resources, or delivering clean water to communities, we’re here to help.

Guam, we’re open for business. Let’s get to work.
