New insight into advection of organic contaminate plume at drain outlet areas

• Provide insight to optimize organic contaminants treatment at the drain outlet areas due to the discharge from the industrial plants.
• Study 56 kinds of organic chemicals regarding their properties.
• Study the general transport equation (GTE) regarding the mass balance for the steady-state analysis of the accumulation of a chemical over time by the plume advection.
• Higher organic carbon-water partitioning coefficient of the chemical will make it easier to stay at the drain outlet area.

To provide insight to optimize organic contaminants treatment at the drain outlet areas due to the discharge from the industrial plants, the fate and transport of variety kinds of organic contaminants were investigated. By taking the chemical properties (molecular weight (MW), Henry’s law constant (H), vapor pressure (Pv), organic carbon normalized soil-water partition coefficient for organic compounds (Koc), water solubility (S), air diffusivity (Da), and water diffusivity (Dw)) of 56 kinds of organic chemical into account, we studied the general transport equation (GTE) regarding the mass balance for the steady-state analysis of the accumulation of a chemical over time by the plume advection. We found that Koc has significant relationship with S and MW of the chemicals. Furthermore, higher organic carbon-water partitioning coefficient of the chemical will make it easier to stay at the drain outlet area, which gives us hints for next research of nanoscale particles for in situ remediation.
