If all input parameters are identical, the spreadsheet and the web calculator should give the same results. The web calculator is linked to the Regional Screening Level databases of toxicity and chemical parameters to provide continuity between the two tools for determining air screening levels and risks. The web calculator is an expansion of the previously provided VISL Spreadsheet for Modeling Subsurface Vapor Intrusion capabilities. VISLs assist Agency staff with making a vapor intrusion determination based on limited, initial data. VISLs are screening level concentrations for groundwater, soil gas (target sub-slab and near-source), and indoor air.
