A reagent system for treating heavy metal-contaminated materials is provided and includes an oxidizer, a soluble phosphate, and an alkaline hydroxide source, such as a caustic soda or lime. A method of treating mine waste bearing one or more heavy metals is also provided and includes the step of admixing a reagent system with heavy metal-containing material to preferentially reduce the leachability of heavy metals and form precipitates and complexes of low metal solubility that remain stable within the host solid matrix for long durations in acidic and abrasive conditions.

Materials for binding per- and polyfluoroalkyl substances (PFAS) are disclosed. A fluidic device comprising the materials for detection and quantification of PFAS in a sample is disclosed. The fluidic device may be configured for multiplexed analyses. Also disclosed are methods for sorbing and remediating PFAS in a sample. The sample may be groundwater containing, or suspected of containing, one or more PFAS.

An ozone cleaning system includes a decontamination chamber, a utility chamber coupled to the decontamination chamber, and a utility assembly disposed within the utility chamber. The utility assembly is configured to decontaminate at least one of contaminated gear and contaminated equipment positioned in the decontamination chamber by treating organic carcinogens. The utility assembly includes an ozone generator configured to provide ozone to the decontamination chamber, a humidifying unit configured to provide humidity to the decontamination chamber, and a vacuum blower configured to at least one of (i) generate a vacuum within the decontamination chamber and (ii) pull the ozone from the decontamination chamber following a decontamination process.
