Disclosed are novel solutions in which a preexisting sediment capping system is integrated with improvements such as a cap ingredient processing and delivery apparatus, cap processing method and novel compositional cap product, whereby a hazardous site is remediated by delivering at least one novel cap composition layer over the contaminated subaqueous waterway or terrestrial substrate floor. One embodiment includes a powdered activated carbon (PAC) based cap layer produced by the system and methodology disclosed, the cap layer ingredients comprising predetermined ratio amounts of dry PAC and dry powdered 2-Hydroxypropyl guar gum (HGG) used as a safe and effective delivery ingredient, blended in a cap processing and delivering apparatus with a dewatered sand semi-slurry, the processed resulting capping composition being delivered in a manner such that a novel PAC cap layer is provided to a cap placement area in need of remediation.

A tufted geotextile for covering and closing land surfaces with shear resistance to hydraulic and dry-flow displacement of infill, having a backing sheet tufted with first yarns to form a plurality of first tufts that extend a first length as simulated grass blades and tufted with second yarns different from the first yarn for a plurality of second tufts extend a second length as simulated understory grass blades, said second tufts having distal ends that splay to form nexts of discrete fibers extending into interstices between the first and second tufts, and an infill received within the interstices, which next restrict hydraulic and dry-flow displacement of the infill. A method of tufting a geotextile for understory tufts and nests is disclosed. A method of covering outdoor land sites for increased resistance to high shear hydraulic and dry-flow events is disclosed.

A method for on-site aerial dissemination of Oxidatively Converted particles of contamination with substantial atmospheric disposal, commonly known as aerosolization, of the water component of all untreated or partially treated leachates and all untreated or partially treated wastewaters. These leachates and wastewaters (defined as water containing 2 or more detectable and known contaminants) are collected on site and the defined leachate or defined wastewater, having multiple defined and known contaminating suspended and perhaps precipitated solids therein, and aerially disseminating or aerially oxidizing or commonly known aerosolizing said contaminants over a chosen contaminant collections area (defined as 1-300 meters from the nozzles) and disposing of the water component of the leachate or wastewater through atmospheric disposal and lastly evaporation on the site of the leachate or wastewaters' generation. The commercial process can be known as AerosoliZLD leachate or wastewater disposal under the intent of Federal Zero Liquid Discharge (ZLD) regulations.

This method improves and controls ex-situ or in-situ, aerobic or anaerobic digestion of organic materials and toxic or damaging compounds through increased control of multiple chemical and biological settings and conditions. The ability to control flow, natural processes, and biological activity, while adjusting to individual site conditions, offer many opportunities to modify results. Large quantities of modified or adjusted organisms are developed and utilized. Identification and strategic manipulation of the multiple elements of the system result in performance modifications. Energy is utilized to manipulate characteristics of a natural degradation system.

A method and system for on-site aerial dissemination of oxidatively converted particles with substantial atmospheric disposal of the water component of all regulated and defined leachates and regulated and defined wastewaters. These leachates and wastewaters (defined as water containing 2 or more detectable regulated, defined and known contaminants) may include collecting the leachate or wastewater, having multiple contaminating suspended and perhaps precipitated solids therein, and aerially disseminating and disposing of said leachate or wastewater on the site of its generation. The defined leachate or wastewater is directed to an Integrated Mobile Aerosolization System (IMAS) having a turbine and being fully integrated and mobile. Thereafter, the mixture is directed from the IMAS and the contaminants aerially disseminated and disposed of over a defined and designated area on the site where the defined leachate or wastewater is created.

The invention relates to a MSW landfill barrier system capable of prolonging breakthrough time of leachate and a manufacturing method thereof. The system comprises a leachate collection and removal layer, a first HDPE (high-density polyethylene) geomembrane infiltration proof layer (2), a clay liner (5) and a groundwater collection and removal layer (6) which are sequentially stacked from top to bottom. The clay liner (5) is composed of a lower clay liner (51), a middle clay liner (52) and an upper clay liner (53) which are sequentially arranged, wherein the middle clay liner (52) is filled with a medium-fine sand layer (7) laid with sands of particle sizes ranging from 0.1 mm to 0.5 mm and of water content 3%, wherein the saturated hydraulic conductivity of the medium-fine sand layer (7) varies from 110.sup.5 to 110.sup.3. A method of manufacturing the MSW landfill barrier system capable of prolonging breakthrough time of leachate is also provided.

A substrate and a slurry for erosion control and/or hydroseeding are disclosed. The substrate includes mulch and a cover composition including bentonite clay and cellulosic water dispersible polymer or starch. Other desired optional ingredients may also be included. Methods of controlling or reducing erosion control are also disclosed.

A manufactured composite comprising synthetic turf and impermeable geomembrane is used in a single-layer capping system as the single layer to provide permanent, impermeable and functional aesthetic cover for land reclamation. During installation of composite pieces at a job site, an edge portion of a tufted section of a second composite piece is overlaid onto an edge untufted section of the first composite piece already laid and anchored over foundation soil to form a reinforced overlapping seam, through which the two composite pieces are physically and permanently joined together. As composite pieces are joined together, the continuity of synthetic grass and the continuity of impermeability are extended and realized over the entire site to form permanent, impermeable and functional aesthetic cover for land reclamation.

A reinforced wall system comprising fill material, a plurality of facing baskets, a plurality of reinforcing members at least partially disposed within the fill material, and an impermeable membrane at least partially encapsulating at least a portion of the fill material and one or more of the reinforcing members. Each of the plurality of reinforcing members is associated with a corresponding facing basket. An outer end of each reinforcing member is above a substantially horizontal portion of the corresponding facing basket. The facing baskets and the reinforcing members are positioned in a plurality of layers, with each layer comprising one facing basket and one corresponding reinforcing member. The impermeable membrane is positioned to span two or more layers of the plurality of layers. At one or more layers of the plurality of layers, a portion of the impermeable membrane is positioned around an outer end of the corresponding reinforcing member.

A system for the controlled distribution of capping material and the capture of dust and particulates includes an enclosure having a top wall and a continuous perimetrical side wall with an open bottom end. A cyclone inside the enclosure separates the air, dust, and particulates from solid materials. The air, dust, and particulates are exhausted from the enclosure to a filtering system. The solid capping material passes from the cyclone to a hopper and then to a spreader for the controlled distribution of the capping material through the open bottom end of the enclosure.
