URS & Dow

"URS’ Dow Business Unit was tasked with performing Dense Non-Aqueous Phase Liquid remediation at a former chemical plant.
The scope of work included collecting soil and groundwater samples, and completing pilot testing in advance of In-Situ Chemical Reduction and Oxidation for mass reduction of the constituents of concern. The team used air-rotary drilling to clear underground obstructions, resulting in 2,072 injection points. This set the stage for ground treatment. Each injection point was then treated with Cool-Ox®, a calcium peroxide-based agent that was injected into the remediation target zone of subsurface soil. During these field activities, an unmarked underground storage tank was discovered and remediated. The Cool-Ox® treatment removed ~311,000 lbs. of COCs (67%). The project team was acknowledged for working safely for 9,020 hours over five months—one of the coldest periods in Philadelphia’s history. The Remediation Leader formally recognized the exemplary safety effort: “Thank you all for your hard work and attention to safety during this major project at the Philadelphia plant. We were all committed to making this project a very safe and productive one [and] we succeeded because of the close cooperation of Deep Earth Technologies, Inc."
