The United States Interstate Technology and Regulatory Council (ITRC) recently published their newest guidance document, Implementing Advanced Site Characterization Tools. Advanced site characterization tools (ASCTs) are capable of rapid implementation and data generation and can be used to provide data for a more precise and accurate conceptual site model. Although these tools have been available for several years, they often are not used because users perceive them to be expensive and unavailable, or do not understand how ASCTs work and how to interpret the acquired data.
Over the past two years, a team of environmental experts worked together to create this comprehensive guidance to assist stakeholders with the selection and application of ASCTs, as well as the interpretation of data gathered by ASCTs to evaluate the best cleanup options for a project. The guidance divides ASCTs into four categories: Direct Sensing, Borehole Geophysical, Surface Geophysical, and Remote Sensing.
To support the selection and use of ASCTs, this free guidance includes:
- An ASCT Selection Tool that provides an interactive dataset to identify appropriate tools for collecting geologic, hydrologic, and chemical data,
- Summary Tables that provide additional information to evaluate the applicability of each tool,
- Case Studies that provide examples of the use of tools at a site,
- Checklists that provide information to be considered when planning to use a tool, describe typical content of a report, and identify appropriate quality control checks, and
- Training Videos that provide an overview of the ASCT document and examples of the application of select tools.
