Electrical Resistivity

Electrical resistivity imaging is another technique used for over 90 years to characterize the electrical properties of subsurface materials.

Resistivity measurements are made by introducing an electrical current into the earth between a pair of electrodes and measuring the potential electric current between a second pair of electrodes. By using a long string of electrodes, this allows for a series of resistance values to be determined for the subsurface features, which can then be processed and interpreted into a 2-D cross-section of the subsurface environment.

The great advantage of electrical resistivity imaging, is that it can be used to image geologic features from tens of feet to several hundred feet in depth, and still maintain excellent resolution.

Mundell & Associates uses resistivity methods solve other problems like mapping geologic features such as strata, faults, and karst features; as well as to delineate landfills, locate and quantify amounts of aggregate resources, and others.

Don’t Top Off Your Gas Tank

Why?

  1. Topping off the gas tank can result in your paying for gasoline that is fed back into the station’s tanks because your gas tank is full.
  2. Gasoline vapors are harmful to breathe
  3. You need extra room in your gas tank to allow the gasoline to expand.
  4. Topping off your gas tank may foul the station’s vapor recovery system.
