    摘要： Composite particles contain a natural stone or aggregate core and a coating of two or more sorbent layers collectively containing at least two distinct kinds of sorbent materials effective for sorbing two distinct contaminants. One or both sorbent layers may be mixed with a water-absorbent, swellable clay that, upon contact with water, causes spalling or disintegration of the coating layer to release the sorptive material into a body of water such as a pond, ditch, stream, or riverbed. Additional swellable or protective layers may also be present. The composite particles are deployed into a pond, ditch, river, or streambed where the core of natural stone remains in the riverbed. The sorptive materials of the two different sorbent layers sorb and fix a wide range of contaminants, including both the heavy and light-weight hydrocarbons, from the water, and settle as a fine sediment. The sediment with sorbed contaminants is then removed by means such as hydraulic collectors or dredging.

    摘要： Contaminated sediment is re-mediated using a self-regenerating reactive sedimentation capping system comprising a system of composite particles having a core and a coating. The coating of at least some particles further include a complexing or sorptive reactive material, such as activated carbon, appatite, a clay or organoclay, or a synthetic sorptive such as Sorbster™. The same or different particles contain a composition of dormant microbes capable of utilizing various contaminants as a food source. The same or other particles may also contain nutrients, micronutrients, vitamins, cofactors, buffers or other adjunctive compounds to sustain the microbes. The microbes feed on and degrade the contaminant compounds complexed, absorbed or adsorbed by the reactive material, thereby regenerating the reactive material for re-use.

    摘要： The invention relates to a low-permeability geotechnical barrier material including a blend of approximately equal parts of: aggregate particles, sand-size particles and manufactured composite particles that include a hydratable sealant material composed of naturally-occurring clay minerals and/or polymer-enhanced clay minerals, such that the actual percentage of clay mineral component is less than 10% by weight in the blended material. In a particular embodiment, the construction of a low-permeability geotechnical barrier using predominantly coarse grain materials by conventional compaction efforts is rarely attempted due to the difficulty of maintaining a uniform mix of well-graded sand and aggregate blends necessary to achieve low permeability. The regularly achievable permeability offered by this material blend when installed with specific proscribed techniques using conventional equipment can be 5×10−8 cm/sec or lower.

    摘要： Reactive treatment cells (RTCs) are described in combination with sediment capping systems as a means for environmental remediation. RTCs include an impermeable housing defining an interior, a permeable ceiling and floor typically including filtration materials such as geotextiles, and at least one interior compartment for treatment reagents. One RTC includes a gabion-like cage structure retaining a geomembrane-supported geosynthetic clay liner (GM-GCL) housing, while a second embodiment includes a hard, cylindrical shell as a replaceable reagent cartridge. RTCs may be employed in initial capping system installations or retrofitted into existing capping systems. RTCs may include optional baffles, flow restrictors, floating discs, sensor probes, and two or more serial reagent zones or compartments.

    摘要： Composite particles of a hard core coated by a layer of hydratable, swellable clay such as bentonite are useful for constructing, modifying and/or supporting lifeline structure such as dams, berms and levees, and/or pipelines or conduits for oil, gas, sewage, water, or cables or wires for transmission of electrical power or data information. The method involves placing the composite particles in a location within, below, or about the lifeline structure, and hydrating them to cause them to swell and fill and seal the voids around the structure to form a resilient support having a high damping ratio and low hydraulic conductivity that is maintained after exposure to strain forces. The composite particles are advantageous in damping seismic waves and reducing the potential damage from an earthquake, explosion, tremor, fatigue loading, or similar seismic event.
