Below are a sample of the many industries we provide leak location and leak detection services for:


The mining industry presents many unique opportunities for geophysical applications that cannot be solved by standard engineering or monitoring methods alone.  Applications  range from mapping subsurface leaching fluid flow and saturation on heaps, pond liner leak location, fluid injection monitoring for enhanced recovery, to the mapping of subsurface controls on acid rock drainage (ARD), and off site seepage of ARD and pregnant leach solution (PLS).

Government & Nuclear

HGI has conducted a broad variety of geophysical investigations at the U.S. Department of Energy’s Hanford Nuclear Reservation in south central Washington State.  Since 2000, HGI has been monitoring underground storage tanks on the Hanford Site with our Leak Detection and Monitoring technology (LDM).  Utilizing the electrical resistivity methodology, LDM can detect and monitor leaks, and estimate leak volumes surrounding the underground storage tanks containing highly radioactive and hazardous chemical wastes.  Additionally, HGI developed an extensive and large base of relevant project experience in performing Surface Geophysical Exploration (SGE) studies aimed at characterizing waste sites and underground storage tanks sites containing highly radioactive and hazardous wastes.

Energy & Nuclear Energy

HGI employs a number of geophysical methods to locate and map buried infrastructure and objects including, subsurface pipelines and infrastructure, underground storage tanks (USTs), buried monitoring wells, and more.  Subsurface pipelines and infrastructure and  cooling and containment ponds all present the possibility of contaminants leaking into the environment via breaches or holes.  HGI possess the expertise and experience to locate or monitor for leaks in pipelines and ponds in a variety of environments and settings.   Because of HGI’s extensive work at the U.S. Department of Energy’s Hanford Nuclear Reservation in south central Washington State, the United States Nuclear Regulatory Commission has recommended using HGI’s electrical resistivity methods for leak detection & leak location at U.S. Nuclear facilities.  HGI’s methods and technology are discussed on pages 21 – 27 in the U.S.NRC document NUREG-2151, ‘Early Leak Detection External to Structures at Nuclear Power Plants’.


The production of industrial chemicals involves the conversion of raw materials such as water, oil, gasses, and minerals into products used in our everyday lives.  Many of these products and byproducts are liquid in nature and stored in containment systems such as ponds and tanks, as well as transported through pipes during processing at the production facility or to the final user.  Wherever there are liquid substances there is the possibility of leaks occurring either via transport or storage.  HGI has the ability to detect and locate or monitor for leaks  in containment or transportation structures associated with the chemical industry.


HGI’s leak detection technology has been used to monitor fluid flow in an oil reservoir during a surfactant test at the Rocky Mountain Oil Field Testing Center (RMOTC).  Test results confirm the ability of the methodology to detect the movement, direction, and rate of fluid flow at reservoir depths.  Additionally, this same technology is used to find leaks in containment systems, such as lined ponds, commonly used in the oil and gas industries.


Geophysical methods have proven to be an efficient and effective means for characterizing the subsurface geology and hydrogeology associated with landfills.  As a result, geophysical characterization of landfills is now a routine practice and a variety of techniques can be applied to define landfill properties such as, leachate circulation, regional contamination from offsite seepage, and leak location in leachate ponds.


Geophysical methods are used in agriculture as a way to provide non-invasive data to help characterize the soil and near-surface.  Common applications include soil moisture mapping and monitoring, soil characterization, salt water intrusion, monitoring application and effectiveness of fertilizers, site infrastructure mapping, and leak location & detection in ponds, pipes, and irrigation canals.  Depending on site conditions and project objectives, electrical resistivity, electromagnetic (EM), and/or ground penetrating radar (GPR) methods are often utilized.

Public Works

Many Public Works projects require infrastructure that control or move water or other fluids as part of basic operations.  These structures can and will develop leaks over time through usage, age, or accidental operator error.   Many of these structures such as dams, canals, reservoirs, pipelines, and sewage operations are buried in or below the earth’s surface.  This simple fact leads to challenges in locating leaks when these containment systems fail.  HGI uses and develops cost effective geophysical technology and methodologies for detecting leaks and assessing the integrity of such structures.
