High Resolution Site Characterization

Welcome to our comprehensive portfolio of High Resolution Site Characterization (HRSC) and subsurface imaging services. Our state-of-the-art techniques and innovative tools are designed to provide unparalleled insights into subsurface conditions, enabling more informed decision-making, efficient project execution, and sustainable environmental management.

At the core of our services is High Resolution Site Characterization (HRSC), a suite of direct sensing tools utilized with Direct Push Technology (DPT) drilling rigs. Our HRSC toolkit includes the Hydraulic Profiling Tool (HPT), Electrical Conductivity (EC), Optical Image Profiler (OIP), and Membrane Interface Probes (MIP). These advanced tools offer a detailed and accurate understanding of subsurface conditions, surpassing traditional boring and monitoring methods.

HRSC and Subsurface Imaging Toolbox

  • Hydraulic Profiling Tool/Electrical Conductivity (HPT/EC)
    • Measures pressure, flow, and permeability through water injection.
    • Evaluates bulk soil conductivity and groundwater Specific Electrical Conductance (SEC).
  • Optical Imaging Profiler (OIP)
    • Utilizes three different light sources to induce petroleum fluorescence, captured by a CMOS camera or photometer.
    • When combined with HPT/EC, provides detailed hydrostratigraphic data in a single log run.
  • Membrane Interface Probe (MIP)
    • Heats soil to release volatile organic compounds (VOCs), which are then analyzed by three detectors.
    • Operates in standard or ultra-sensitive low-level modes.
  • Groundwater Profiling Tools (HPT-GWP, HPT-GWS)
    • Logs injection pressure and flow, and collects discrete groundwater samples at six-inch intervals.
  • Cone Penetrometer Testing (CPT)
    • Measures geotechnical soil parameters, including tip resistance, sleeve friction, and piezometric pressure.
  • Pneumatic Slug Testing (PST)
    • Conducts high-resolution slug tests in small diameter wells or Geoprobe Discrete Screen-Point samplers.
  • Real-Time Data & Subsurface Imaging Reports

Real-time Reporting 

Our HRSC and Subsurface Imaging Tools are boltstered by real-time comprehensive reporting services which include:
  • Real-Time Data Review: Data from our tools are processed and viewed as boring logs in real-time on our data acquisition computer. Logs are printed into readable PDFs, locations are posted on a live Google Earth Map, and data is uploaded to a cloud site for immediate review and decision-making.
  • Post Processing and Basic Reports: Our Basic Final Report includes a summary of field activities, log-run summary table, QA/QC review, color graphic logs, contoured sensor value maps, and optional data exports.
  • Advanced Interpretive & 3D CSM Visualization Reports: Our Advanced Report offers scaled log plots, fence diagrams, 3D model diagrams, integration of laboratory results, and advanced QA/QC data review.

The HRSC Advantage

A recent study sponsored by the U.S. Environmental Protection Agency (USEPA) titled “High Resolution Site Characterization at Petroleum Underground Storage Tank Release Sites – Applicability, Benefits, and Costs” highlights the significant advantages of HRSC:
  • Enhanced Geological and Contaminant Understanding: HRSC provides a comprehensive view of site geology and contaminant distribution, leading to better-informed corrective action decisions.
  • Accelerated Project Timelines: By improving the accuracy of site assessments, HRSC helps achieve “No Further Action” status more quickly, saving 3 to 8 years in project time.
  • Cost Efficiency: HRSC reduces overall project costs by 9% to 19% through decreased monitoring expenses and more targeted remedial activities.
