Influence of groundwater table fluctuation on the non-equilibrium transport of volatile organic contaminants in the vadose zone

The migration of volatile organic compounds (VOCs) from groundwater is an environmental concern because of the risk of vapor intrusion. In coastal aquifers or areas under the influence of systematic pumping, groundwater table fluctuations may be significant, which may affect VOC flux. This study developed a one-dimensional numerical model to simulate VOC mass transfer from groundwater to the vadose zone to the atmosphere, which was validated...
