Description of Services: The Cost of Remedial Action (CORA) Model is a computerized expert advisor used to recommend remedial actions for Superfund hazardous waste sites and estimate their costs. The stand-alone PC-based system may also be used for RCRA corrective action sites. The model is designed for both current site-specific estimates and for program budgeting and planning. The system provides recommendations for remedial action technologies on a site-specific basis, and provides a method to estimate remedial action costs in the pre-feasibility stage of analysis.
Data: The CORA Model is comprised of two independent subsystems:

Expert System allows a user to enter site information generally accessible at the remedial investigation stage and recommends a range of remedial response actions from among 44 technology descriptions contained in the system. It includes descriptions of innovative treatment technologies:

  • Soil vapor extraction
  • Solidification
  • Soil slurry bioreactor
  • Pressure filtration
  • Soil flushing
  • In situ biodegradation
  • In situ stabilization

Cost System develops order of magnitude (+50/-30%) cost estimates for the technologies selected and may be used to independently assess remedy recommendations from other sources.

Access: The model is available from the contact below for a cost of $280, which includes a run-time version of the system and 1 hour of technical assistance.
Hardware/Software: The CORA Model is a stand-alone application, not designed for LAN use. The following are the hardware specifications:
