Monitoring the efficiency of ISCO treatments, typically involves measuring concentrations of contaminants, and persulfate or its byproduct (sulfate). However, sole reliance on concentration data presents several limitations.
For this, researchers from MAiMA (Stable isotopes and mineralogy), research group from the University of Barcelona with more than 25 years in isotope geochemistry have developed IscoTracer. This is a stable isotope analysis, consisting of a multi-isotopic toolbox supported by cutting-edge technology. scientific excellence and analytical quality assurance.
Potential benefits
This new methodology provides several benefits such as:
Key information for ISCO monitoring:
- Oxidant: influence area and remaining reactivity.
- Contaminants: extent of degradation of each contaminant.
Optimization of oxidant further injections: Better dose calculation, better planning of spatial and temporal distribution of injections. Decision-making support tool: whether the ISCO treatment needs adjustment.
Time and cost savings: More efficient ISCO application.
Stage of development
The team has tested their development at laboratory-scale, with field-scale validation undergoing in 2 sites.
MAiMA is looking for feedback about the industry’s needs, which will enable further development of the technology. The team is open to collaboration with organizations interested in adopting or supporting the implementation of this technology.
