In Situ Chemical Oxidation Treatability Studies

ISCO treatability studies are bench-scale laboratory tests that determine whether selected chemical oxidants can degrade particular compounds of concern.

ISCO studies can help you answer the following questions: 

  • Will the compounds of concern that I’m targeting degrade using a specific oxidant dose? 

  • Which oxidant will work best at my site? 

  • Which activation chemistry should I choose? 

  • How much oxidant will I need? And what concentration should I use? 

  • How quickly will compounds of concern degrade under my remediation plan? 

  • Could mobilization of metals or gas generation occur? And if so, how likely is that? 

Under the right conditions, in situ chemical oxidation (ISCO) can help to rapidly degrade difficult compounds of concern at a site. Before deciding whether and how to use ISCO, you need to know how effective the method is likely to be at your site and for the specific contaminants you are addressing.

ISCO treatability studies are bench-scale laboratory tests that measure oxidant demand and determine whether selected chemical oxidants can degrade particular compounds of concern. Using soil, sediment, rock, or groundwater from your site, our batch reactor and column studies monitor compound of concern degradation under different conditions and test treatment variations to meet the needs of your site.

Customized Studies with Dependable Results 

SiREM’s experts can conduct ISCO treatability studies in small batch reactors, flow-through columns, and custom set-ups to understand how treatment is likely to work at your site.  

Our studies can help you accomplish the following: 

  • Evaluate which oxidant will likely work best.  

  • Fine-tune oxidant type and dosing. 

  • Optimize your remedy with low-risk, on-thefly changes in the lab. 

  • Incrementally identify and manage risk from the lab scale to pilot studies to full scale treatment. 

  • Reassure stakeholders early on that your selected approach is feasible. 

In addition to fully scoped ISCO treatability studies evaluating contaminant destruction, SiREM performs base demand and natural oxidant demand (NOD) tests following standard published methods.

Our tests routinely address the following oxidants, methods, and technologies: 

  • Permanganate 

  • Activated persulfate (including matrix, heat, alkaline, peroxide, permanganate, and iron activation) 

  • Hydrogen peroxide/Fenton’s chemistry 

  • Ozone 

  • Combined technologies with ISCO, including bioremediation or surfactant washing 

  • Electrokinetic studies to evaluate enhanced distribution of oxidants 

All studies are replicated, controlled experiments that provide a high level of data integrity and interpretability. You’ll receive reports that summarize data and place results in the context of your remediation project so that you can select and optimize a remedy for your site.
