High Resolution Site Characterization Technologies

COLUMBIA Technologies performs high quality environmental site assessments and characterizations using advanced high-resolution site characterization (HRSC) tools and real-time techniques that can detect and map the full extent of subsurface contamination, track soil and groundwater changes and profile existing remediation systems. These include:

  • Membrane Interface Probe with Electrical Conductivity (MIP/EC),
    a multipurpose tool for mapping soil and groundwater contamination, specifically volatile organic compounds (VOCs), such as halogenated solvents and petroleum compounds, and for measuring soil electrical conductivity (EC).
  • Laser Induced Fluorescence (LIF),
    a Non-Aqueous Phase Liquid (NAPL) mapping tool used to delineate the depth and lateral extent of free product and residual phase petroleum contamination.
  • Hydraulic Profiling Tool (HPT),
    provides direct pressure response measurements of hydraulic permeability and flow to determine migration pathways, remediation injection regions, and placements for groundwater monitoring wells.
  • Membrane Interface Probe-Hydraulic Profiling Tool (MiHpt),
    a combined MIP-HPT probe for mapping soil and groundwater contamination, specifically VOCs, along with measurements of soil EC and HPT injection pressure – all in the same push!
  • Cordless Cone-Penetrometer Testing (CPT), a direct push tool combines the efficiency of lightweight, mobile technology with cordless CPT technology to determine the subsurface stratigraphy in situ (in place) and to estimate geotechnical parameters of the materials present. These cordless CPT probes can be used from a variety of push platforms to provide continuous data, repeatable penetration results, and cost savings over more traditional boring and sampling methods.
