The Interstate Technology & Regulatory Council Implementing Advanced Site Characterization Tools Team, Report No. ASCT-1, 328 pp, 2019

This document helps state regulators and other practitioners understand, evaluate, and select advanced sited characterization tools (ASCTs) to develop and refine site conceptual site models. It describes site characterization tools that can quickly deliver semi-quantitative or qualitative data to identify locations and depths where quantitative data should be collected and aid in visualizing and understanding the physical and environmental characteristics of a site. ASCTs in this document are divided into four general categories: direct sensing tools, downhole geophysical tools, surface geophysical tools, and remote sensing tools. An interactive ASCTs Selection Tool helps identify appropriate tools and information for collecting geologic, hydrologic, and chemical data. Once one or more prospective tools have been identified, more detailed information about a tool can be obtained by reviewing the description of the tool in the web-based document and the Tool Summary Tables, Case Studies, and Checklists.
