Below is an alphabetical list of contractors who own and operate Geoprobe® Direct Image® equipment and are able to perform some level of direct sensing. They may have equipment to perform some or all Geoprobe® DI services.
Direct Image® contractors listed here have been formally trained by Geoprobe Systems® or one of our authorized representatives on the proper operation of DI equipment. Geoprobe® maintains within the SOP of each system that QA testing must be performed before and after each log by the operator. QA testing ensures that the equipment is operating properly and provides validity to the logs. It is the recommendation of Geoprobe Systems® that the hiring firm requests current system performance data from the potential MIP service providers to ensure the system is capable of detecting specific target compounds and achieving site requirements.

Our team provides detailed EnISSA-MIP investigations to the consulting community, problem owners or contracters. The EnISSA method uses a GCMS system which is connected to the MIP by an innovative gas sampling system. Individual components can be characterised with low detection limits in the µg/l range. It is possible to qualify and semi-quantify pollutants within the time frame of conventional MIP. Our on-site operators are experienced in the data interpretation and are able to give real-time feedback during a dynamic sampling plan. Typically each 30 cm, concentration data for individual compounds are generated and graphed on-line together with soil structure (EC and/or CPT). This allows the operator to determine the location of the contaminant, the relative concentration and the soil layer in which the contaminant is located.
