Electromagnetic Surveys – Getting All The Data

Electromagnetic (EM) surveys consist of using either time-domain or frequency-domain electromagnetic field generating systems to measure and map changes in the electrical/magnetic properties of the shallow subsurface. For shallow site investigations, EM methods are commonly used to map variations in either soil properties or to detect and map the location of buried man-made objects or altered ground. Applications range from mapping the lateral extent of contaminated soils to locating underground features such as storage tanks, drums, pipelines and utilities.
