What it is
PCBs (polychlorinated biphenyls) are chlorinated oils that were once used in transformers and capacitors. They are banned and persistent, and they build up in the food chain.
How MuniRem® treats it
MuniRem lists PCBs among compounds it treats. Its case studies booklet says the reagent degrades PCBs and explosives into nitrogen gas, formate and non-hazardous trace elements. No PCB-specific test data was found.
- MuniRem arrives as a dry powder. Crews mix it into contaminated soil or sludge, or dissolve it in water to spray, pour or soak surfaces.
- Adding water starts the reaction. The reagent releases sulfoxyl free radicals, a short-lived reactive form of sulfur.
- The reagent's reducing chemistry strips chlorine from oxidized organic compounds such as chlorinated solvents.
- An EPA-certified laboratory tests the treated material before any disposal decision.
This material is evaluated case by case with a treatability study before any full-scale work.
What it becomes
Chloride (general), Non-hazardous trace elements.
Where it's found
Old electrical equipment sites and mixed-contaminant soils.
