CVI2D Toolkit (2018)
A chlorinated vapor intrusion screening tool for 2-D soil gas concentration profiles in heterogeneous soils
This excel spreadsheet tool can be used to estimate two-dimensional soil contaminant gas concentration profiles in heterogeneous soils, such as are encountered in layered soil scenarios or those in which vertical soil moisture content variations are important.replicate.

PVI2D Toolkit (2021)
A new petroleum vapor intrusion screening tool for 2-D soil gas concentration profiles
This excel spreadsheet tool can replicate two dimensional soil gas profiles of hydrocarbons and oxygen as Abreu and Johnson 3-D numerical model, and can provide very similar predictions of indoor air concentration as the numerical model. A senitivity analysis and a simplified Monte Carlo sensitivity analysis is also included in the spreadsheet.
