Contamination and Remediation: Scaling Novel Technologies | Marlaina Auger

The STAR technology was applied as the primary remedy to achieve regulatory closure at a 37-acre former industrial facility in Newark, NJ. Both a surficial fill unit (ground surface to ~10 ft bgs) and an alluvial sand unit (~10-40 ft bgs), impacted with residual and free-phases of coal tar from the historic operations at the site, were remediated via smoldering combustion. STAR was applied at the site using three independent treatment systems operating ‘cells’ consisting of multiple ignition points (IPs), vapor extraction wells, and interstitial thermocouples. Ignition points (i.e. standard two-inch steel wells) were installed within impacted zones and connected to an air supply to support the combustion reaction, while removable in-well 9 kilowatt (kW) heaters were deployed as the ignition source for the combustion process. Vapor extraction wells were installed within the cell to capture vapors for treatment using conventional above ground means (i.e., thermal oxidizer). Interstitial thermocouples were installed to monitor temperatures in the subsurface during operations. Cell cycle times were short (days) and following treatment the equipment was removed and reused in another treatment area at the site. Drilling, STAR operations, and remedy verification activities took place concurrently to accelerate the remediation process and facilitate the rapid transfer of the property to the new site owner.
