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!
