Project Highlight - Pneumatic Fracturing and Chemical Oxidation at a Site in Huntsville, AL

The site, a former drum storage area, contained TCE soil and groundwater concentrations ranging up to hundreds of thousands of ppb, with suspected presence of product phase in the subsurface. Cascade completed a field-scale chemical oxidation pilot test at an active government facility in Huntsville, Alabama. The project scope consisted of integrating Pneumatic Fracturing and the injection of Fenton’s reagent to address dense non-aqueous phase liquid (DNAPL) source contamination within both the unsaturated and saturated zone at the site.
