Abstract: A cartridge sampler for collecting a target species from an environment for subsequent chemical analysis includes removable collection media having at least one molecule sensor thereon. The cartridge sampler includes a means for tagging a geospatial location and time that the fluid samples are provided to the collection media such that the location and time that the fluid samples are provided to the collection media can be later determined. Also disclosed are systems and methods for collecting species from various environments including a subsurface formation, a pipeline, and gaseous, soil or sub-slab, and aqueous environments. The cartridge sampler is fitted on or within a device designed for moving within each environment.

Abstract: A method of waste treatment includes treating partially-dewatered matrix with a first electron-beam radiation dose. The treated partially-dewatered matrix is transferred to a digester where the treated partially-dewatered matrix is subjected to anaerobic digestion. Biogas is recovered from the treated partially-dewatered matrix during the anaerobic digestion. The treated partially-dewatered matrix is dried and subjected to a second electron-beam radiation dose.
