Effective remedial strategies based on fractured bedrock characterization

Hydrogeologic Evaluations of Fractured Bedrock Systems

Fractured bedrock is a common component of hydrogeologic systems and can pose unique environmental and engineering challenges that are less common in more homogeneous porous media systems. Fractures and other forms of secondary porosity (e.g., dissolution cavities) typically control the hydraulic properties of the rock and are the primary means of fluid flow and mass transport in bedrock. Understanding the interconnectivity of the fractures and the connection between the fractures and overlying geologic units is essential for development of robust conceptual models of these groundwater systems. Those conceptual models help stakeholders select effective remediation strategies for adversely affected sites with fractured bedrock.

Numerous methods and techniques are available to improve the characterization of fractured bedrock. These methods can be used to estimate hydraulic parameters, map the connectivity of fracture systems, and obtain information about the overall conditions of a groundwater system. Techniques range from low-effort, low-cost methods, such as hydrograph analyses, to more involved options, such as large-scale pumping tests. These techniques can often be conducted in tandem to provide more robust evaluations of fractured bedrock systems. Applying these methods and techniques while also understanding their limitations and potential difficulties can improve the evaluation of fractured bedrock systems and save stakeholders time and money when developing effective remedial strategies.
