Successful remediation decisions at contaminated sites depend on the quality of the collected data, accuracy of data analysis, and interpretation of that data during site assessment and characterization. This webinar presents various case studies, which demonstrate how to apply HRSC strategies using direct sensing tools advanced using direct push technologies (DPT) and interpretive techniques to support and improve remediation decisions at sites. Examples of direct sensing tools include: hydraulic profiling tools (HPT), membrane interface probe (MIP), flame ionization detector (FID), photoionization detector (PID), and electrical conductivity.

High resolution site characterization strategies and techniques involve a flexible, scalable, and phased approach to site characterization and remediation, and they reduce uncertainty by identifying site characteristics such as:

  • type and behavior of contaminants;
  • vertical and horizontal extent of contaminate distribution;
  • media affected;
  • sources (mass);
  • pathways (transport zones); and
  • storage zones controlling contaminate movement (dependent on lithology, stratigraphy, permeability).

The HRSC systematic approach results in a detailed conceptual site model that is continuously refined over the life of the project and can be used to make successful remediation decisions, which result in faster and more effective site cleanups.
