Title: Site Evaluation and Design Considerations for In-Situ Remediation Success!

B. Rakewich and K. Jackson, Nichols Environmental (Canada) Ltd.

So you are managing a contaminated site and are considering an in-situ approach as opposed to more traditional remedial technologies, but you are not entirely sure your site is a good fit.  You are in luck!  This presentation will provide guidance on how to thoroughly evaluate a site’s potential as an in-situ remediation candidate and how to properly design your in-situ remediation program.

A review of site evaluation considerations will be provided including historical assessments, soil and groundwater chemistry, site infrastructure, buried facilities, soil lithology, hydraulic conductivity, data gaps, health and safety requirements, and the need for a bench scale evaluation.  Once you have the confidence that your site has a high potential for success utilizing in-situ remediation techniques, we will take a closer look at how to design your project for success.

Design considerations will be provided including amendment selection (chemical oxidation vs. in-situ chemical reduction), application techniques and technologies, real-time monitoring, post-remediation monitoring, and verification sampling.  A brief overview will be provided of the various amendment products currently on the market and their effectiveness in remediating specific contaminants.  We will also provide a detailed discussion on the various amendment application techniques including low pressure vs high-pressure injections, direct push injections, injection well installation, and infiltration galleries.  Finally, we will discuss real-time monitoring during the in-situ remediation program and provide some considerations for post-remediation monitoring and verification sampling.
