The Soil Vapor Extraction Endstate Tool (SVEET) is a spreadsheet that allows users to easily enter information and obtain the estimated groundwater concentration results that are calculated for one or more scenarios conforming to the generalized conceptual model. PNNL has updated SVEET as part of the ESTCP Project, "Development of a Decision Support Tool for Vadose Zone Remediation of Volatile Contaminants." The update to SVEET2 permits an expanded range of input parameter values, thereby enhancing the applicability of the tool for DoD and other sites.
