Electrical Conductivity (EC) |
This system measures soil conductivity for the determination of site lithology in unconsolidated materials. During a push, the field instrument applies an excitation current to the probe and collects data from the probe and a depth measuring stringpot mounted on the probe unit. The computer plots the soil conductivity versus depth.
We recommend running 1-2 EC logs near continuously logged borings to “calibrate” the EC response. Then the logs can be produced across the site with a high understanding of what the unconsolidated composition is made of. |
Advantages:
-
Continuous logs for the entire depth of the borehole.
- Conductivity can be logged independently or in conjunction with the MIP system
- Independent EC logging can exceed 400+ feet per day.
- Identify confining clay units and zones of contaminant transport.
- High data density generated, 20 data points per foot for the entire depth of log.
- View the geologic changes as the logs are being produced.
- Log graphs are printed immediately after the log is completed.
- The logs can be inputted into 2D or 3D cross-sectional maps of the site.
- Delineate chloride contamination from salt storage facilities in clean sand aquifers.
-
Eliminates soil cuttings during the logging process.
