1 Clean-up of Tank Battery Impoundments & Well Head Areas is Now a Reality William L. Lundy,, Principal DeepEarth Technologies, Inc.

2 Site Background Tank Battery Site - 1,000 cubic feet of crude oil impacted soil, heavily saturated Release occurred approximately 5 years ago Site underlain with a hard clay layer at 6 Well Head Approx. 20 sq ft. of aspaltines around well head where ground was impacted by hydrocarbons over time

3 Work Scope

5 Challenges: Persistent Small Leaks Smelly and Unsightly Weathered crude oil takes on characteristics of asphalt paving

6 Plan of Action: Kill the strong odors at the site Jump start the remediation process at the weathered site Demonstrate the Cool-Ox Technology to: - Kill Odors upon contact - emulsify crudes and allow them to be separated from the soil mass to be recovered or simply disposed of in a fuel program.

7 Application: DTI s Field Crew applied approximately 175 gallons of Cool-Ox reagent to each site DTI s Hydro-Dart Tooling mixed the soils and applied the reagent to penetrate the depth of contamination

13 How Does it Work? Cool-Ox generates hydrogen peroxide from solid peroxygens that are injected into the soil or groundwater in an aqueous suspension. Once in place, the peroxygens react with the water to produce hydrogen peroxide. The low solubility of the peroxygens allows them to be distributed throughout the sub-surface prior to reaction and increases the probability of contact with the contaminant!

14 Results

15 What Happened? Saw good results after treatment but A second release occurred on the site

16 Additional Sites Soil samples treated with Cool-Ox from Natural Gas Production Facilities in Colorado. Please note the great reduction in the SAR levels!
