Abstract

The Membrane Interface Probe (MIP) from Geoprobe Systems in Salina, Kansas, is a logging tool which can be driven into the soil to determine lithology and estimate the relative concentrations of VOC contaminations both in unsaturated and saturated zones(1). VOC molecules, present in the gaseous, dissolved, solid or free product phases move by diffusion through a heated semi-permeable membrane and are carried up to specific detectors at the surface. One implicit use of the MIP is to delineate subsurface contaminations in the three dimensions and/or to put in place samplers for site monitoring. Since the MIP probe is typically pushed at a rate of 30 cm/min, it has become the ideal tool for quick, semi-quantitative delineation of VOC plumes, allowing 5 profiles down to 20 meters to be done in one day, depending on the local geology.
