In Situ Remediation Technologies and Site Reuse

why innovate
Why Innovate?
  • Key drivers in contaminated site restoration:
    • Cost
    • Uncertainty
  • Still a relatively young industry experiencing change in several areas, mainly:
    • Technology innovation
    • Advances in project management
    • Shifting market drivers
  • This presentation touches on each of these areas
    • Snap shot of the drivers for innovation
    • The Triad: Synthesizing practitioner experience in smart project management to reduce cost and uncertainty
    • Technology innovation: Demand and supply side information
    • Brownfield Technology & Redevelopment Support Center

real time analytical and sampling technologies
Real-Time Analytical and Sampling Technologies
  • Field analytical, rapid sampling, mobile labs, quick turnaround off-site all allow real-time or near real time analysis
  • Rapid turnaround results support dynamic decision making
  • Lower costs of field methods support increased density (address sampling uncertainty)
  • Field results guide confirmation (address analytical uncertainty)
  • Decision support software can help organize and process data, plan field activities

Subsurface CSM from high density data (DP-MIP sensing)

Groundwater Remedies

We’ve broken the P&T “monopoly”

  • In situ remedies are more mature, diverse and specific
    • In 1991, 5% in situ GW remedies; in 2002, 24%
  • Time, experience, and technology are allowing us to optimize the pumping, treating, and monitoring components of long term P&T systems.
  • As with source control, we are using a “rich” mix of remedies, with a more robust tool box to address each scenario
