New In Situ Remediation Mapping Technique Studied by Leading Academics in Sweden Shows Promise

Four leading remediation professionals from Sweden’s academic community have published findings about a new subsurface mapping technique. Their paper investigates the ability to map in situ treatment of chlorinated solvents within the subsurface, using direct current resistivity and time-domain induced polarization tomography (DCIP). The study was completed on a contaminated site in Sweden, where a 3-D Microemulsion® pilot trial had been completed. The results show the extent of the treatment achieved and suggest that this is a promising method for verification of treatment zones.

Long-Term, Low-Cost Remediation of Chlorinated Solvents

3-D Microemulsion is an injectable electron donor optimized for low-cost, long-lasting in situ remediation of chlorinated solvents. Its engineered, wide-area, subsurface distribution significantly reduces the number of injection points and events required, resulting in time and cost savings. A viable, long-term source of staged-release hydrogen on the order of 2-4 years from a single application, this technology is faster and often lower cost than lengthy natural attenuation approaches.
