Webinar | Fractured Bedrock Characterization: A Case Study Implementation of Parsons Bedrock Matrix Tool

Overview

Join us on January 17, 2024 for a technical webinar regarding Fractured Bedrock Characterization: A Case Study Implementation of Parsons Bedrock Matrix Tool.

Presentation Description

Background/Objectives

Characterizing environmental contamination in fractured bedrock is challenging due to the inherent nature of the complicated hydrodynamic system, especially when compared to the better understood characteristics in unconsolidated soil and groundwater systems. Oftentimes stakeholders lack the knowledge base for evaluating remedial investigations and remedial actions in bedrock. Parsons was tasked with developing an evaluation “tool,” using a variety of published referenced documents, to help regulatory agencies at these challenging sites.

Approach/Activities

Parsons developed a Bedrock Matrix Tool, an investigation reference guide, to help investigation teams and regulators evaluate work plans and conceptual site models for thoroughness and detail, focusing on a robust understanding of geology, hydrology, and chemistry of the fractured rock system. During a phased site investigation, aspects of the tool were implemented, such as rock coring and on-site laboratory analyses, downhole geophysics, packer testing, and borehole fluid replacement tracer testing.

Results/Lessons Learned

A case study demonstrating the use of the Bedrock Matrix Tool and advanced geological/hydrogeological analyses for a remedial investigation at a fractured bedrock chlorinated solvent site in New York State will be presented. The key to successful fractured rock site characterization is using multiple tools for multiple lines of evidence and employing highresolution
data collection methods. The presenters will demonstrate the use of a variety of tools and techniques for development of a discrete fracture network approach to hydrostratigraphic
unit development and show applicability to the Bedrock Matrix Tool.

Presenters: Jim Schuetz, PG and Tayler Schweigel
