Soil Decontamination and Remediation

Site Capping

Solutions to managing contaminated soil and former landfill sites can involve capping of the site with clean fill or specific designed liner systems. IES have significant experience in the capping and construction of liner systems at contaminated sites.

Permeable Reactive Barriers (PRBs)

Where groundwater contamination is present on a site at a relatively shallow depth, a technology that has gained acceptance is the installation of a permeable reactive barrier. Permeable Reactive Barriers are designed to treat contaminated groundwater as it flows through the barrier. IES have installed bentonite cement walls with funnels of zero valent iron for groundwater treatment. IES are able to install PRBs comprising zero valent iron, activated carbon, compost or other reactive substrates as specified.
