At sites impacted by volatile organic compounds (VOCs), vapor intrusion (VI) is the pathway
with the greatest potential to result in actual human exposure. Since sites with VI were first …

Vapour intrusion (VI) is the phenomenon by which volatile organic compounds (VOCs)
migrate from the subsurface source through the soil and enter into the overlying buildings …

This paper presents a simplified approach for the soil gas gradient method for estimating
natural source zone depletion (NSZD) rates of specific contaminants of concern (COCs) at …

Appropriate characterization of site soils is essential for accurate risk assessment of soil
vapor intrusion (VI). In this study, we develop a data assimilation method based on deep …

Benzene, as the representative compound in volatile organic chemicals (VOCs), widely
exists in contaminated sites. Adsorption performance of clay minerals can retard the …

In this study we present an analytical solution of a two‐dimensional petroleum vapor
intrusion model, which incorporates a steady‐state diffusion‐dominated vapor transport in a …

This study investigates the influence of density-driven transport on chlorinated vapor
intrusion through modeling and experiments. Density-driven transport involves downward …

The study of the variability of soil gas concentrations is crucial for defining effective
monitoring and remediation strategies and for the risk assessment related to the emission of …

Vapor intrusion from volatile subsurface contaminants can be mitigated by aerobic
biodegradation. Laboratory column studies with contaminant sources of chlorobenzene and …

In this work, we introduce a screening method for the evaluation of the natural attenuation
rates in the subsurface at sites contaminated by petroleum hydrocarbons. The method is …
