Gregg Drilling is pleased to announce that it has added a new tool to its suite of in-situ probes. For years, Gregg Drilling has partnered with other providers to push the Membrane Interface Probe (MIP) in conjunction with the Cone Penetration Test (CPT). For the first time, Gregg Drilling will now offer MIP, making Gregg a one-stop shop for any contaminant screening. The MIP is used for environmental screening on projects requiring an efficient method of profiling VOC contaminants.
The new MiHPT detects volatile organic contaminants (MIP), measures soil electrical conductivity (EC) with a standard dipole array as well as incorporating the Hydraulic Profiling Tool (HPT) to measure injection pressure using the same down-hole transducer as the stand-alone HPT system. Using simple post-processing, you can estimate hydraulic conductivity (K) and water table elevation.
How it works:
The MIP can be attached behind the CPT so both probes can be operated in a single push. A small membrane on the side of probe is heated to 120C. The heated membrane causes VOCs in the soil to mobilize and cross over the membrane due to diffusion. Nitrogen, a carrier gas passing by the inside of the membrane picks up the VOCs and sweeps them to the surface to be detected. Detectors consist of a PID (BTEX), XSD (Chlorinated solvents such as TCE and PCE) and FID. Detection limits: BTEX 0.2-2.0ppm (PID), TCE & PCE 0.2-2.0ppm (XSD)
