XDD's Focus on Innovative Technologies:

• Aerobic / Anaerobic Bioremediation / Natural Attenuation
• In-Situ Chemical Oxidation (ISCO)
• In-Situ Chemical Reduction (ISCR)
• Metals Stabilization
• Thermal Treatment
• Experience with Traditional Technologies:
• Groundwater Extraction & Ex-Situ Treatment
• Air Sparging / Soil Vapor Extraction
• Multi-Phase Extraction

XDD specializes in remediation of recalcitrant contaminants including chlorinated solvents, petroleum hydrocarbons, manufactured gas plant (MGP) residuals, wood preserving wastes, PCBs and heavy metals such as arsenic, chromium and lead.

State of the Art versus State of the Practice
XDD's philosophy is to optimize the application of each and every technology we use - new or old - to provide state-of-the-art remediation systems as opposed to relying on generic state-of-the-practice approaches. Our aptitude with state-of-the-art technology is rooted in a thorough understanding how a technology works, what its limitations are, and what level of treatment can reasonably be expected with any particular application.

Over the past 25 years, XDD staff has developed an extensive toolbox of remediation techniques by embracing new technologies and advancing existing ones. XDD has led the rapidly advancing field of ISCO for the past 10 years by taking permanganate, activated persulfate, and catalyzed hydrogen peroxide oxidation chemistry from R&D to commercial application. A prime example is our X-Ox Process™ (patent pending) that took several years to develop and remains the most effective iron-chelate activated persulfate oxidation technology on the market.

XDD is equally committed to optimizing the use of existing technology as evidenced by our recent successful demonstration of the U.S. Navy-designed Adjustable Depth Air Sparging (ADAS) technology.
