What is High Resolution Site Characterization (HRSC)?
HRSC provides a more complete understanding of contaminants in the subsurface than can be achieved with traditional site characterization methods, and provides these results in a single mobilization. These technologies provide accurate delineation of the source zones and plumes for use in initial site characterization efforts, risk assessments, and remediation planning.
HRSC is also useful for monitoring during and after remediation. It allows for real-time adjustments to optimize the remedy and ensure remediation goals are achieved through distribution verification of amendment distribution, and short and long term contaminant mass reduction from baseline or pre-remediation conditions.
Cascade provides the site characterization help you require. When you need a high level of confidence in your site characterization, we can assist with high resolution methods, dynamic work strategies, and the latest technologies.
We combine HRSC technologies, expert investigation program design and data interpretation, and three-dimensional (3D) data visualization to help you build accurate conceptual site models (CSMs) you can trust. Our services include:
- HRSC tool selection and program design assistance
- Confirmation soil and groundwater sampling
- Data and results interpretation
- 3D data visualization
- Specific integration with our injected remedies team to provide
- Targeted remediation design support
- Design optimization testing (DOT) for injected remedies
- Tight timelines – The speed and higher degree of certainty result in getting to the correct answers sooner
- Risk assessment – Reduced uncertainty reduces the size of built-in safety factors. Better risk assessments may open up land use scenarios that were not previously feasible
- Remediation feasibility studies – HRSC methods and tools provide the best quality and density of data to increase the accuracy of remedy selection. May identify complexities that could lead to Technical Infeasibility waivers, or avoid remediation through other administrative mechanisms
- Remediation design – Reduced uncertainty and ability to target data gaps directly result in a more appropriately sized and successful remediation program, saving money and time
- Site complexity – Multiple plumes, heterogeneous soils, etc. will require better data to navigate the matrix of administrative and engineering challenges toward a positive outcome
- Litigation support – Higher quality data and a lower level of uncertainty combine to meet the onerous demands placed upon site investigations that become the subject of litigation
