XDD, LLC PROVIDES STRATEGIC ISCO ADVICE IN FMC'S FIELD APPLICATION WEBINAR
August 26, 2009

In-situ chemical oxidation (ISCO) has emerged in recent years as a useful tool in remediating a wide range of contaminants under a variety of site conditions. However, there are many methodologies available to design, apply and monitor ISCO with different potentials for success, dependent on site-specific conditions. To help further understanding of ISCO as a remedial option, Brant Smith, Ph.D., P.E. of XDD discussed basic field application strategies during a webinar entitled "Design and Applicaton Strategies for Klozur® Activated Persulfate." The free webinar was part of a series being produced by FMC Corporation, the makers of Klozur® Activated Persulfate. Individuals who could not attend the 8/26 webinar can view a copy of XDD's presentation here.

Dr. Smith's presentation began with an overview of remedial goals, contaminant distribution and site characteristics which impact ISCO strategy selection, and then proceeded to discuss the various methods involved in designing, implementing and monitoring ISCO systems. Specific topics addressed include:

Establishing contact
  • Site-specific geology / hydrogeology
  • Contaminant mass and distribution
  • Injection strategies
    • Direct injection
      • Flow down designs
    • Recirculation systems
    • Pull-Push techniques
  • Other design basics
Monitoring progress / success
  • Site-specific geology / hydrogeology
  • Monitoring objectives
  • Expectations and remedial goals
  • Soil vs. groundwater sampling
  • Sampling strategies
    • Grab
    • Composite

Site owners or project managers who are interested in learning more about ISCO design and application issues are encouraged to contact either Dr. Brant Smith (smith@xdd-llc.com) or Mike Marley (marley@xdd-llc.com) for more information.
