Disclosed are a process and a system for treating contaminated soil. The process includes introducing a contaminated soil to an agitation unit. Ozone is supplied to the agitation unit thereby forming a soil-gas mixture, and the soil-gas mixture is agitated for sufficient time for the ozone to contact the contaminants thereby forming an ozone-treated soil and a residual gas-particulates mixture. The ozone-treated soil and the residual gas-particulates mixture are removed from the agitation unit. If necessary, remaining ozone is then flushed from the soil. The process occurs under negative pressure to prevent ozone from being released to the atmosphere.

A method for the treatment of waste by plasma treating the waste to destroy the hazardous organic components and to yield a slag and an off-gas by plasma treating the waste in the presence of added oxygen gas in a transferred-arc plasma treatment unit, followed by directing off-gas from the plasma treatment unit to a thermal oxidizer combustion chamber.

An apparatus for extracting contaminants from a contaminated material, such as contaminated soil and animal manure, includes an extraction tank having an interior, a heating element that is adapted heat the contaminated material to a temperature where contaminants in the contaminated material are released therefrom to the interior of the extraction tank, and an agitator that is adapted to agitate the contaminated material as it is being heated by the heating element. The apparatus also includes an air pump that generates a series of positive pressure air pulses at an outlet thereof and a series of negative pressure air pulses at the inlet thereof. The apparatus further includes one or more contaminant retaining mechanisms, such as a sediment holding tank, a fluid holding tank, and a gas filter. The interior of the extraction tank, the air pump, and the contaminant retaining mechanisms are connected in a closed loop air circulation system such that the contaminants that are released from the contaminated material are stored in the contaminant retaining mechanisms.

Systems and methods for performing bioremediation using the Geobacillus sp. bacterial strain are provided which are capable of effectively degrading Benzo[a]pyrene (BaP) and efficiently degrading other ring-based organic contaminants. The exemplary bioremediation methods include steps for administering an effective, degrading amount of the bacteria to soil containing excess amounts of BaP and incubating the bacteria administered to the soil at a given temperature and for a duration that are suitable for promoting incubation and reducing and the concentration of BaP below a maximum concentration, as might be specified by a regulatory body.

Apparatus and methods for removing, measuring, and/or mapping per- and polyfluoroalkyl substances (PFAS) present in porous media such as soils, sludges, and colloids by employing both direct and indirect heating methods to transfer thermal energy to the media undergoing treatment. The contaminated media is placed within a media treatment enclosure that incorporates a thermal jacket, and radiatively heated by circulating a heated gas through the thermal jacket. The contaminated media is directly heated by injecting heated treatment gas into the media treatment enclosure. The heated treatment gas is drawn over and/or through the contaminated media to mobilize contaminants from the media and into the treatment gas, which is then collected and processed to recover the contaminant.
