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.
An improved remedial capping system, comprising an integrated ingredient processing and delivery apparatus, said apparatus capable of on-site processing of a cap layer composition further comprising a powdered activated carbon (“PAC”) absorbent ingredient, hydroxypropyl guar gum powder (“HGG”) delivery ingredient, dewatered sand carrier ingredient, the said composition being processed in a manner such that the cap layer composition is delivered to a subaqueous area in need of remediation partially through the use of said integrated apparatus.
A cap layer processing and delivery apparatus, comprising one or more capping layer ingredients added therein in a manner such that the resultant blended composition is capable of remediating a hazardous site.
A cap layer produced by the system, the layer comprising a powdered activated carbon (“PAC”), a powdered 2-Hydroxypropyl guar gum (“HGG”) used as a safe and effective delivery ingredient, the cap layer being processed and combined on the vessel using water and sand in slurry form, and in a manner such that a novel GPAC cap layer is processed by the blending apparatus, and further delivered in a manner to provide a cap layer over a capping area in need of remediation.
An integrated apparatus for processing capping ingredients and delivering a capping composition, comprising;
An improved integrated apparatus that allows for the blending and delivery of a plurality of capping ingredients in a manner such that the resultant blended composition is a PAC cap layer covering a subaqueous waterway bottom substrate.
