  • Patent number: 8049056
    Abstract: A method and system for the reduction of contamination in soil and groundwater is provided. A clathrate of ozone and a cyclic oligosaccharide can provide for an extended zone of influence due to, for instance, the improved stability of the ozone. The clathrate can include cyclodextrin and ozone and can improve the oxidative destruction of organic and inorganic contaminants.

  • Patent number: 7667087
    Abstract: Disclosed is a method, apparatus and system for the remediation of contaminated soils, groundwater and water. A combination of reagents such as persulfate and ozone or persulfate, ozone and hydrogen peroxide may be used to enhance destruction of organic contaminants. Reagents may be injected into the smear zone to trap and destroy volatile compounds that may otherwise escape treatment.

  • Patent number: 7659123
    Abstract: In general, the purpose of the probe system is to provide improved rapid field methods using re-designed direct push technology (DPT) and “push-pull testing” concepts to evaluate in situ chemical, biochemical, surfactant, adsorptive media, and leaching and fixation remediation technologies for hazardous subsurface contaminant(s). The probe system and methods described here when applied to a hazardous waste site being considered for in situ remediation of contaminants (organic or inorganic) by the listed treatment technologies will yield information that greatly reduces the uncertainty with regards to treatment effectiveness for the in situ soil, groundwater, and contaminant(s) conditions affecting dosage requirements and reaction rate(s) for various reactants.
