Amongst their extensive qualifications, SiteQuest Services staff hold advanced degrees in geology, have completed academic training in geophysical techniques, and hold Professional Geologist licensure. All surveys are completed or supervised by an OSHA 40-Hour HAZWOPER trained, licensed Professional Geologist with over 20 years of industry experience.
SiteQuest Services’ highly skilled staff are equipped with the newest state-of-the-art GPR systems and magnetometer equipment. We are trained in GPR investigations, with an emphasis on utility locating, by an internationally recognized GPR manufacturer in New England. While most GPR operators are trained “on the job,” we make the extra effort to train our staff in GPR competency before “having a go at it.”
Whether you need a GPR survey completed to supplement a utility locate, to find underground storage tanks or buried drums, to identify voids, or to map a cemetery or other important historical heritage sites, you can count on SiteQuest Services to tell you where stuff lies beneath the ground.

Ground penetrating radar (GPR) systems are advanced geophysical instruments designed for non-destructive subsurface imaging and detection. These systems utilize electromagnetic pulses to penetrate various materials, allowing for the visualization and characterization of subsurface features such as utilities, underground storage tanks (USTs), archaeological artifacts, and other geologic structures & buried objects. With their versatile capabilities, GPR systems have become invaluable tools in a wide range of applications, including civil engineering, environmental assessment, archaeology, and forensic investigations.
At the core of GPR technology is the transmitter-receiver antenna unit, which emits electromagnetic pulses into the ground and receives reflected signals from subsurface features. GPR antennas come in various frequencies, each offering specific advantages for different applications. Higher frequencies provide higher resolution but lower penetration depth, making them suitable for shallow subsurface imaging, while lower frequencies offer greater penetration depth but lower resolution, ideal for deeper investigations.
One of the key technical capabilities of GPR systems is their ability to produce high-resolution subsurface images in real time. By analyzing the amplitude, travel time, and phase of reflected signals, GPR systems generate two-dimensional or three-dimensional images of subsurface structures with detailed spatial resolution. These images provide valuable insights into the composition, geometry, and spatial distribution of subsurface features, allowing users to make informed decisions and interpretations.
GPR systems also offer depth penetration capabilities, allowing users to investigate subsurface features at different depths depending on the antenna frequency and soil conditions. With proper antenna selection and signal processing techniques, GPR can penetrate depths ranging from a few inches to several feet, making it suitable for a wide range of applications, including utility detection and UST locating.
Another important technical capability of GPR systems is their ability to discriminate between different subsurface materials based on their electromagnetic properties. GPR can differentiate between materials with contrasting dielectric constants, such as soil, rock, concrete, groundwater, and buried objects. This material discrimination capability enables users to identify and map subsurface features accurately and reliably.
In conclusion, ground penetrating radar systems offer a wide range of technical capabilities for non-destructive subsurface imaging and detection. With their high-resolution imaging, depth penetration, material discrimination, mobility, GPR systems are invaluable tools for a variety of applications in engineering, geoscience, archaeology, and environmental science, providing crucial insights into subsurface structures and facilitating informed decision-making in diverse fields.
