    Abstract: Reactive geocomposite mats, and their method of manufacture, for treating contaminants in soil or water that allow the passage of essentially non-contaminated water therethrough. The geocomposite mat includes a pre-formed woven or non-woven geotextile, having a thickness of about 6 mm to about 200 mm, and having, a porosity sufficient to receive a powdered or granular contaminant-reactive material, contaminant-sorptive material, or a contaminant-neutralizing material (hereinafter collectively referred to as “contaminant-reactant material” or “contaminant-reactive material”) throughout its thickness, or in any portion of the thickness across its entire major surface(s). The powdered or granular contaminant-reactive material is disposed within the pores of the previously formed, high loft geotextile mat to surround the fibers, e.g., by vacuum or vibrating the high loft mat while in contact with the contaminant-reactive material to allow the powdered or granular contaminant-reactive material to flow by gravity into the pores of the previously formed geotextile and vibrational forces. Liquid-permeable cover sheets are adhered to the upper and lower major surfaces of the filled geotextile to prevent the powdered or granular material from escaping from the geotextile during transportation and installation.

    Abstract: Un material de cubrimiento subacuático para cubrir sedimento contaminado, que comprende una pluralidad de partículas compactadas de un material sólido reactivo mezclado homogéneamente con un coadyuvante de dispersión y que se han compactado a una presión manométrica de al menos 1,03 MPa (150 psig), cuyas partículas compactadas tienen un peso específico mayor que 1,0, y un tamaño de partícula en el intervalo de 1,25 mm a 2,54 cm (1/16 pulgada a 1 pulgada), y cuyo tiempo de desintegración para que al menos 50% de las partículas se desintegren a su tamaño de partícula previo a la compactación, una vez que han entrado en contacto con el agua, es de 5 horas o menos; en donde el coadyuvante de dispersión incluye copolímeros acrílicos; polisacáridos, preferiblemente almidón; poliésteres de ácido láctico; una combinación de ácido cítrico y bicarbonato de sodio; proteína de soja; o combinaciones de los mismos; o lignosulfonato; aminas; acrilatos solubles en agua; poli(alcohol vinílico); o polietilenglicol; y en donde el material sólido reactivo es químicamente y/o biológicamente activo para reducir o eliminar la migración de contaminantes del sedimento contaminado.

    Abstract: Reactive geocomposite mats, and their method of manufacture, for treating contaminants in sediment, soil or water that allow the passage of essentially non-contaminated water therethrough. The geocomposite mat includes a pre-formed woven or non-woven geotextile, that is needlepunched to an outer geotextile sheet layer to provide a high loft, structurally secured, pre-formed geotextile having a thickness of about 6 mm to about 200 mm, and having, a porosity sufficient to receive a powdered or granular contaminant-reactive material, contaminant-sorptive material, or a contaminant-neutralizing material (hereinafter collectively referred to as "contaminant-reactant material" or "contaminant-reactive material") throughout its thickness, or in any portion of the thickness across its entire major surface(s). The powdered or granular contaminant-reactive material is disposed within the pores of the previously formed, high loft geotextile mat to surround the fibers, e.g., by vacuum or vibrating the high loft mat while in contact with the contaminant-reactive material to allow the powdered or granular contaminant-reactive material to flow by gravity into the pores of the previously formed, needlepunched geotextile. A liquid-permeable outer geotextile sheet then is secured to the filled geotextile, preferably by heating upwardly extending fibers of the pre-formed geotextile mat to prevent the powdered or granular material from escaping from the geotextile during transportation and installation.

    Abstract: Reactive gabion/geocomposite articles, and their methods of manufacture, fo r controlling contaminants in soil, sediment or water that allow the passage o f essentially non-contaminated water therethrough. The articles and methods described here in utilize gabions, which are box shaped cages or grids (see Fig. 2) made of either ste el wire mesh or plastic. In one embodiment, the reactive geotextile mats are lined on the to p major surface with a gabion cage or grid. In other embodiments, the cages or grids surroun d a geocomposite containing reactive material. The gabion/geocomposite articles can be constructed in-situ (at the site of deployment) or remotely (on land or barg e) and set in place. They are typically placed side-by-side and, in a preferred embodiment, are configured to cover a target sediment area, underwater. The gabion/geocomposite articles m ay be filled with clean sediment, silt, sand and/or concrete block or rock to hold the reactive geocomposite in place and for armoring.
