Environmental and Engineering Site Characterization
We offer noninvasive site characterization using near surface geophysical techniques to address environmental and engineering needs such as listed below.

Subsurface Depth Estimation
Rough estimation of depth interest is critical before undertaking an expensive drilling program for remediation, resources exploration or engineering purposes. Various geophysical techniques such as seismic methods, magnetic or gravity methods can be used to estimate the depth of interest.

Locating and Mapping of Underground Sinkholes
Underground sinkholes are normally void with essentially zero density.
The difference in density between air in the sinkhole and surrounding rocks provides a huge density contrast that allows identification of sinkholes and Bunkers.

Locating and Mapping Abondened Landfills, UXOs
Urban landfills are often full of metallic material such materials can be detected by electromagnetic and magnetic methods making delineation of abandoned landfills UXO and UXB possible using methods such electrical resistivity EM and magnetic methods.

Mapping Subsurface Hydrocarbon Contamination
Hydrocarbons such as Light Non Aqueous Liquid Phase (LNAPLs) and Dense Non Aqueous Liquid Phase (DNAPLs) whether intact or biodegraded can be detected using different geophysical techniques such as electrical resistivity, EM, Ground penetrating Radar (GPR) methods.

Groundwater Exploration
Groundwater is conductive by nature, thus it is possible to employ different electrical methods such as Ground Penetrating Radar, electrical resistivity to map areas of water table and aquifers. The difference in seismic velocities between water and surrounding rocks makes seismic methods a candidate for groundwater exploration as well.

Examination of Bridge Integrity
Rusting of metals inside the bridge concrete slab will cause change in their electrical conductivity properties, such changes can be detected by methods such as Ground Penetrating Radar (GPR).

Archaeological Investigation
Buried archaeological sites may contain metals such as tools and jewel, they can be detected by geophysical methods such as Ground Penetrating Radar (GPR), electrical resistivity and magnetic methods.

Lithological Overburden Mapping
Rocks exhibit range of seismic velocity contrasts such contrasts can be detected and measured by seismic methods such as refraction, reflection.
Gravity and magnetic methods can also be used to map sedimentary basins where significant physical properties contrast exists.

Delineation and Mapping of Onshore Gas Hydrates
The presence of gas hydrates creates a significant density anomaly, which can be detected using gravity and seismic methods.
