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.

Abstract: A method and system for the reduction of contamination in soil and groundwater is provided. Cyclic oligosaccharides can be used, for example, to carry oxidants, carry activators, solubilize organic contaminants and promote biodegradation.

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.

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.

The multi-purpose single probe system can to measure the relative permeability of the subsurface soil and groundwater to a liquid or gas ejectant and recover soil gas, soil, or groundwater samples for contaminant analyses, and can measure the chemical dosage and reaction, dissolution, adsorption, desorption, leaching, or fixation rate of a reactant such as a chemical or biochemical oxidant, metallic or bimetallic dehalogenating agent, surfactant or emulsifier solution, adsorbent media regenerant, leaching or fixation reagent that is injected and withdrawn during a push-pull test.
