Our Goal is to Reduce Contaminant Concentrations

DeepEarth Technologies, Inc. (DTI) is an environmental restoration company specializing in providing Cool-Ox® technology for cleaning up contaminated soils and groundwater. Cool-Ox® has been awarded eleven (11) patents in the US, Canada, Europe and Australia.


The Cool-Ox® process is designed to eliminate a wide variety of contaminants including petroleum hydrocarbons, chlorinated organics (PCP, PCB, DDT, Dioxins), nitrate explosives (TNT, DNT) and brine. It is especially effective at destroying vapor phase contaminants (HC-VOC, CVOC) impacting various types of soils including clay (ChemHydro-Infusion™). While Cool-Ox® is tough on contaminants, it is gentle on vegetation. Because the mechanisms are different, Cool-Ox® can eliminate pollutants while actually promoting plant growth.

"I want to thank you for an excellent job on the RS project. The crew did excellent work each day and worked efficiently.  The equipment functions well and the operation of it is very efficient. James is an excellent crew chief and showed excellent leadership and excellent communication with us.  I appreciate his careful decisions and recommendations. There was good reactivity with the Cool-Ox® and after two years of groundwater monitoring, there has been no rebound."


"There are many factors in how well this project was conducted and this  is a very brief summary of the high points. Again I am impressed with the effectiveness of Cool-Ox® and believe I have a deeper understanding of that after working on this project.

DTI provided excellent leadership for the project with his technical knowledge of the product and its delivery, practical problem solving, excellent organization and planning, effective and serious emphasis on safety, schedule management, and careful and precise communication. I appreciate the willingness to proceed ahead in the face of the approaching Hurricane Harvey while keeping safety as the top priority. The crew all did an excellent job in every part of their work. I am very impressed with the cross training you have achieved to allow the crew to take on each task and they all contributed constantly and consistently. The weather made difficult challenges to the schedule, but the crew exceeded all expectations and completed the project on schedule.

I also am very impressed with your company’s equipment. You have invested in quality equipment capable of doing the job. I have worked with several injection contractors in the last 15 years and common issues are equipment breakdowns and under-sized equipment (especially pumps). Those problems caused large delays and left us unable to perform the work as planned on several projects. Your equipment is up to the task and well maintained.

URS and 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."
