Membrane Interface Probe (MIP)

The Membrane Interface Probe (MIP) is a screening tool with semi-quantitative capabilities acting as an interface between contaminates in the subsurface and gas phase detectors at the surface. The membrane is semi-permeable and is comprised of a thin film polymer impregnated into a stainless steel screen for support.

The MIP can greatly reduce the need for sampling by providing definition of the extent or boundaries of an area of contamination. As a logging tool, the MIP give us in situ information in real-time as to what we encounter in the subsurface. The MIP is the only commercially available tool capable of logging both chlorinated and non-chlorinated volatile contaminants in soil.

The MIP can tell us:

  1. Where the contaminant is encountered at depth.
  2. How the concentration of contaminants at this location compares to the concentration at other locations.
  3. Where the contaminant occurs in relation to lithology.

Patented technology gives you the ability to log volatile organic compounds in soil and unconsolidated sediments.

  • Operates in both saturated our unsaturated materials
  • Detects volatile compounds in the gaseous, sorbed, dissolved or free phases
  • Applicable to both chlorinated and non-chlorinated species
  • Provides simultaneous log of soil electrical conductivity
  • Drivable! Built to withstand percussion driving.

There is no doubt that MIP is a powerful tool and its use is on the increase. MIP has excelled in investigation of TCE and PCE contamination. The MIP log can be used to determine the depth at which a monitoring well should be placed, at what depth samples need to be collected, or the interval for injection of remediation materials.
