Abstract: Remediation materials are stored and treated within remediation cells constructed within a pond. The remediation materials originate from a variety of sources including the pond in which the remediation cells are constructed. The volume of the remediation cells is relatively small compared to the total volume of the pond and thus, the total active volume of the pond to handle stormwater flood events is not significantly diminished. Remediation of the remediation materials in the cells is accomplished through a variety of processes, including dewatering and/or by bioremediation therein. The water level in the remediation cells during normal operation outside flood events is maintained at levels which support the remediation processes. When the remediation cells are filled over time, remediated material can be removed for use in constructing other remediation cells, wetlands or marshes in the same or other ponds or can be located to areas remote from the pond.

Abstract: A temporary berm or bin system, easily transported, erected without tools, and easily dismantled. A set of panels or planks is joined with sliding clips to form a bin having vertical or near vertical sides. The bin is lined with an impervious sheet of geocloth to form a containment berm for use in controlling the dispersal of hazardous material spilled from storage or work facilities. Spring loaded clamps hold the geocloth securely to the uppermost plank without nailing, sewing, or other labor consuming and/or tear prone methods. The berm is particularly suited to protect oil well drilling sites in environmentally sensitive environments such as arctic tundra. No excavation or other disturbance of the soil is required to erect the protective berm. The berm is secured to the ground by spiking through triangular support gussets. In the arctic, securing may be accomplished by freezing ice or mud as an “ice mortar” over the gusset feet and along the lower edge of the planking.
