Soil and Groundwater Remediation
When excavation and disposal isn't a viable or cost-effective alternative, in-situ remediation methods can destroy or contain the contaminants of concern, depending on the technology deployed. In some cases, 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. Amendments can be deployed for solidification/stabilization applications and for use as permeable reactive barriers.
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. Organoclay has high adsorption capacity for oil and grease as well as low molecular weight organic compounds. Commonly deployed for use on manufactured gas plant (MGP) sites or sites contaminated with creosote. Click to learn more about Organoclay.
REACTIVE CORE MAT
Reactive Core Mat (RCM) consists of the selected media needle punch reinforced between two geotextiles for ease of deployment and even distribution of media. Common media within an RCM are organoclay, activated carbon, FLUORO-SORB, or apatite, depending on the application.
RCM can be deployed at a surface to groundwater interface to prevent or limit the migration of contaminants from one zone to the other.
