Contaminated Soil Remediation
DECARB2™'s Extraordinary Soil Solution: This “green” chemistry introduces a proprietary catalytic reagent treatment directly into the contaminated soil to trigger the reaction. Organic contaminants & pathogens are degraded & sterilized; dissolved metals form stable, insoluble metal silicates in the same reaction — at ambient temperature & pressure, with no added energy & no off-gassing.
The treatment is non-toxic and non-hazardous & the resulting treated material are increasingly non-toxic and non-hazardous until they reach an inert state.
Remediate the Material. Reduce the Need to Relocate It.
More than 10,000 tons of hazardous, toxic contaminated soil have been treated using the catalyzed reagent technology with remediation tested as successful and certified with approved for safe return to the environment.
Proven Track Record: Successfully remediated over 20,000,000 pounds of soil contaminated with the following:

Why It's Extraordinary
Standard practice is to excavate-and-landfill a contaminated site, which relocates liability at heavy cost; PCB contaminated soil otherwise requires incineration. Certified on-site conversion to non-hazardous soil eliminates transport, disposal fees, and long-tail liability. Remediation cost is the binding constraint on Brownfield redevelopment and mine reclamation; rather than relying solely on excavation, transportation and off-site disposal, DECARB2 is designed to make successful on-site treatment possible, reducing transportation, disposal requirements and long-term management costs.
On-site remediation of contaminated soil — at a fraction of the cost of conventional methods.

Proof of Performance — Commercial-Scale Field & Lab Data: The soil remediation & recycling facility (Buckeye, AZ) has run this catalytic reagent process in commercial scale, totaling more than 10,000 tons of petroleum-hydrocarbon-contaminated soil, reducing TPH from as high as 55,000 mg/kg to almost entirely below 100 mg/kg, several down to non-detectable. In addition, to commercial scale remediation projects, DECARB2 is independently lab-certified and proven tests are available (EPA Method 418.1, Del Mar Analytical and Analytical Technologies, Inc.). Also, third-party lab testing data is available to confirm measurable single-reaction PCB degradation (up to 51% by weight in 30 days, Associated Laboratories); and field application at the Stringfellow Acid Pits Superfund site (Riverside County, CA) achieved a greater than 20-fold reduction in chromium, independently verified by Brown & Caldwell Laboratories.
