When excavation and disposal isn't a viable/cost effective alternative, insitu remediation methods can destroy or contain the contaminants of concern, depending on the technology deployed. In some cases, a contaminated soil that is otherwise considered hazardous can be amended to bind the contaminants and keep them from leaching from the soil, allowing the soil to be disposed of as a non-hazardous waste.
Vadose Remediation offers amendments that can be deployed in solidification/stabilization applications and permeable reactive barriers.
Contaminants treated include hydrocarbons, chlorinated solvents, and metals.
Organoclay is an effective way to attract and hold organic compounds found in contaminated groundwater and sediment. Moreover, Organoclay is an effective stabilization agent that allows Portland cement to cure properly. Click to learn more about Organoclay.
Zero Valent Iron (ZVI)
ZVI is capable of reducing chlorinated solvents to harmless components. Additional contaminants degraded by ZVI include heavy metals and metalloids and nitroaromatic compounds.
