Presentation Overview:

The overall objective of this series of webinars is to explore and provide experience using publicly-available simulation and data analysis tools that can be used individually or in combination, to support remediation decisions and strategy development for sites contaminated by chlorinated solvents, petroleum hydrocarbons, or other constituents. The webinars will focus on questions such as:

  • Will source remediation meet site goals?
  • What will happen if no action is taken?
  • Should I combine source and plume remediation?
  • What is the remediation timeframe?
  • What are achievable and reasonable remediation objectives?

The discussion will focus on the unique features of selected models and how those features can support strategy development and effective remediation decisions. Emphasis will be on REMChlor and REMFuel, recent simulation tools developed for the U.S. EPA and DoD. These tools simulate both source and plume behavior and remediation options. By providing the ability to simulate sites where conditions change in space and time, REMChlor and REMFuel can provide information "equivalent" to the types of output from more sophisticated numerical models and can assist environmental professionals in rapidly and efficiently developing and optimizing strategies for cleaning up sites.

This first of five modules will introduce the concept of mass balance based screening level models for supporting remediation efforts at sites contaminated by chlorinated solvents, hydrocarbon fuels, and other contaminants. The key questions related to remediation decision making will be discussed, and the EPA REMChlor and REMFuel computer models introduced. The contaminant source model (DNAPL or LNAPL) used in the REMChlor and REMFuel models will be described in detail.
