Remediation Support Services - System Audit

Process

Our technical and programmatic audits accurately assess a system’s level of performance and effectiveness, determining whether a remedial approach is still valid, both technologically and financially.

The data is inputted into numerical and analytical models that evaluate remedial timelines, financial, and technical risk, and provide a measure of probability of success for the current technology to reach the remedial goal for the site.

The process typically takes three to four weeks to complete.

 

 

Details

In conjunction with our internationally recognized experts, IRSL combines historical performance data and the Conceptual Site Model (CSM) to evaluate the historical and current performance of the existing remedial system.

Depending on the approach being audited, IRSL will develop a matrix of performance factors, including:

  • Run time
  • Mass removal
  • Mass removal rate versus time
  • O&M cost with time
  • Areas of influence and capture
  • Monitoring data
  • Etc.
