Assessments undertaken to determine the risks to the subsurface environment frequently adopt quantitative contaminant fate and transport models. These models are often used in predicting the outcome of both subsurface contamination and surface contamination distribution.

What is the benefit?

Models may be used to determine the risks to receptors from land, groundwater or airborne contamination or from specific activities, such as landfilling. Outputs are flexible and may include predictions of travel times to receptors and concentrations of contamination to reach receptors. The models can also be used to design or test remediation strategies once an unacceptable risk to the environment or other receptors has been identified.

Why CRA?

The CRA family of companies has specialist expertise in air, soil and waterborne contaminant fate modelling. Services provided include:

  • Data interpretation;
  • Derivation of remedial targets;
  • Groundwater flow modelling using 2D and 3D packages;
  • Contaminant fate and transport modelling using 2D deterministic and probabilistic packages;
  • 3D modelling of contaminant fate and transport;
  • Assessment of contaminant degradation and daughter products; and
  • Design and assessment of the efficacy of remedial solutions.
