Webinar Description: 

This 2-hour webinar is designed to take LSPs beyond the traditional qualitative Conceptual Site Model (CSM) by adding an overlay of quantitative information that sharpens decisions and provides documented support that can be important to an LSP’s practice. The Quantitative Conceptual Site Model (QCSM) approach provides the professional with a functional version of the CSM that can be used to guide investigations, assist in remedial design or test the effectiveness of a remedy, and can provide a documented, science-based tool for sound decision making.

The CSM has long been used by investigators, and described in regulatory guidance, as an integral part of environmental site investigation and remediation activities; providing site investigators, regulators, and other interested stakeholders with a tool to better understand site conditions, identify data needs, and make decisions regarding site cleanup planning and implementation. But the traditional CSM is typically qualitative in nature, consisting of narrative and/or pictorial descriptions of contamination sources and subsurface conditions at a contaminated site. The Quantitative Conceptual Model (QCSM) approach, which involves the merging of quantitative analysis results with the framework of a sound site conceptual model, provides a functional tool for sound decision making.

The workshop will provide an overview of CSM guidance from a variety of sources (including documents developed by Interstate Technology and Regulatory Counsel (ITRC), and United States Army Corps of Engineers (USACE)), and a discussion of how the conceptual models developed in accordance with these documents benefit from the incorporation of quantitative analyses at all stages of a project. Instructors will discuss the QCSM approach, and will describe quantitative analysis tools and techniques that can be applied in any project, ranging from simple calculations, to more complex analyses, including spatial data analysis methods, 3-D Data visualization techniques, and groundwater flow and contaminant transport analyses that can range from "back of the envelope" calculations to more complex computer models. The course will also discuss the importance of adequate data resolution and data quality during field investigations to facilitate QCSM development.

Additionally, a QCSM case study will also be presented. Finally, attendees will receive copies of select spreadsheet calculators and modeling software (along with simple examples to work through independently) that can be utilized to add a quantitative component to their CSMs.
