Electrical Resistivity Site Assessments & Environmental Audits
Electrical resistivity is a valuable tool for assessing a site’s status and stability. At GeoSearches Inc., we use it to determine the electrical characteristics of subsurface areas resulting from changes in composition and contamination levels in bedrock, soil, and groundwater. Electrical resistivity can be used to determine water table depth, indicate contaminant location, and pinpoint underground faults and burdens. Part of our deliverable for every project is a detailed technical report of our findings, ensuring that you have written technical details for the duration of your project. Contact us for more information about our electrical resistivity site assessments and environmental audits.
What Is Electrical Resistivity?
Electrical resistivity tomography (ERT) is a geophysical technique for imaging subsurface structures using electrical measurements made at the surface or by electrodes in one or more boreholes. It is closely related to the medical imaging technique EIT (electrical impedance tomography) and is mathematically the same inverse problem. However, ERT contrasts with medical EIT by using a direct-current method.
Induced polarization is a related geophysical method that measures transient response. It evolved from electrical prospecting techniques that predate digital computers where anomalies or layers were sought.
