The key to cost savings at corrective actions sites is reducing the scope of costly remediation through the implementation of sound risk assessment principles.  Regulatory agencies have recognized risk assessment as a viable alternative to site remediation, though the manner and degree to which risk-based techniques are permitted to be applied to a site varies from agency to agency.  Our staff has been at the forefront of the implementation of risk-based corrective actions, and has provided regulator education and assisted governmental agencies in the development of risk-based programs in Ohio, Argentina, Brazil, and Puerto Rico.

Among the risk assessment principles in which we specialize are:

  • Groundwater flow modeling
  • Contaminant transport modeling
  • Predicted contaminant loading
  • Plume migration
  • Chemical natural attenuation
  • Geochemical fingerprinting
  • Leaching studies
  • Indoor air modeling
  • Soil contaminant leaching modeling
  • Data validation and management
