Contaminant Fate and Transport

Modeling of Groundwater Contaminant Fate and Transport

Groundwater can become contaminated from a wide variety of natural and anthropogenic activities. Using Visual MODFLOW, and a combination of MODFLOW and MT3DMS, or RT3D, or PHT3D, you can simulate the movement of contaminants in the groundwater.

MT3D models dissolved solutes in groundwater including the following common problems:

  • dissolved plumes
  • simple reactive transport
  • injection wells
  • waste lagoon, landfills, contaminant spills
  • non-point source pollution

Simulating contaminant transport requires an understanding of three concepts:

  1. Principles of natural attenuation: the physical processes within the hydrogeologic environment that affect solute concentration along flowpaths through the system
  2. Principles of modeling solute transport: how MT3D and RT3D implement each of these principles
  3. Solution techniques for the transport equation: techniques for solving the mathematical equation that is defined within MT3D/RT3D; for example, UFD, MOC, TVD, …

Once you have simulated the historical movement of contaminants to present-day, you may be interested in evaluating various remediation alternatives. Learn more about how Visual MODFLOW can be used for assessing a wide variety of groundwater remediation techniques.
