In Situ Remediation - B. Rakewich

The site evaluation process is of the utmost importance when it comes to designing an in situ remedial program.  Outside of identifying your contaminants of concern, having a thorough understanding of plume dynamics, soil lithology, groundwater chemistry, hydraulic conductivity, and site infrastructure are key components that need to be considered during the evaluation process.

A thorough site evaluation will help narrow down your amendment selection, which should almost always be vetted through a bench and/or pilot study.  Once you have confidence that your site is a solid candidate for in situ remediation, the remedial program can be tailor-made specifically to the site.  Multiple amendment delivery technologies (which can be applied simultaneously) should always be considered as part of the design phase, which will ultimately help reach the remedial end points established for a site.  Lastly, real-time monitoring needs to be in place during amendment delivery to document the radius of influence and reactivity of an amendment – and a well thought-out monitoring/sampling program after amendment delivery will provide you with the opportunity to evaluate the effectiveness of the in situ remedial program.  We all want to have successful project completion, so why wouldn’t we take the time to properly evaluate our site and design an in situ remedial program that will give us the best possible outcome?
