MIP & HPT
The Membrane Interface Probe (MIP) is a rapid
in-field soil and groundwater analysis system
that can detect volatile organic compounds (VOCs)
and petroleum products to depths of up to
a hundred feet or more. It is deployed on a cone
penetrometer system that pushes a probe into
the ground. Portable analytical equipment allows
analysis in nearly real-time.
The Hydraulic Profiling Toolm (HPT) is a logging tool that measures the pressure required to inject
a flow of water into the soil as the probe is advanced into the subsurface.
This injection pressure log is an excellent indicator of formation permeability. In addition to
measurement of injection pressure, the HPT can also be used to measure hydrostatic
pressure under the zero flow condition. This allows the development of a hydrostatic
pressure graph for the log and prediction of the position of the water table.
