SVEET2: Development of a Decision Support Tool for Vadose Zone Remediation of Volatile Contaminants
Abstract
A volatile organic compound (VOC) contamination source in the vadose zone presents a potential threat to underlying groundwater and/or to nearby structures through vapor intrusion. Soil vapor extraction (SVE) is a commonly applied remediation technology to address VOC contamination in the unsaturated zone. SVE performance assessment guidance provides a structured approach to evaluate whether the SVE system should be terminated, optimized, supplemented, or transitioned to an alternative remedial approach. The ability to quantify impacts of the remaining source area on groundwater and soil gas are critical to a performance assessment in support of such remedial decisions. The SVE Endstate Tool version 2 (SVEET2) is an updated version of the SVEET spreadsheet software for estimating contaminant concentrations in groundwater and soil gas that are caused by a vadose zone contaminant source. SVEET2 has a rigorous basis from numerical model simulations for a generalized conceptual model that cover a set of parameters and contaminants that are relevant to a wider variety of sites than SVEET version 1.0. The software update includes results from over 5500 numerical simulations to provide these expanded options for site applicability.
