GEOPHYSICAL INVESTIGATIONS


One of the most difficult aspects of geology and hydrogeology is that the subsurface soil, bedrock and hydrologic conditions are rarely directly observable. Traditionally, drilling and sampling have been the primary method for subsurface characterization. This works well for small investigations where the subsurface conditions are relatively uniform.

CarHowever, for larger investigations and those sites where subsurface conditions are variable, obtaining the large number of borings and samples necessary to properly characterize the site can be costly, while too few borings may produce an inaccurate interpretation of the subsurface conditions.

In these circumstances PELA can apply one or more geophysical methods to rapidly collect a larger and more relevant set of data for site characterization.

We perform:

  • Resistivity, seismic, and magnetometer surveys
  • Spontaneous potential surveys
  • Ground penetrating radar surveys
  • Down-hole geophysical logging including resistivity, potential, caliper, natural gamma, and temperature
