IAI provided design-build-operate geotextile tube dewatering and water treatment services for this Remedial Action project. TSCA and Non-TSCA regulated sediments were processed separately in the same dewatering facility, at a flow rate of 3,000 gpm. The water treatment facility met the non-detect PCBs discharge limit throughout the project.
PCBs Remediation
The most common sediment contaminant that IAI has encountered in our sediment remediation and environmental dredging projects is polychlorinated biphenyls or PCBs. PCBs may also be referred to as Arcolors, the historical trade name of this group of synthetic chemicals. Below is a list of projects where IAI has performed remediation work, and PCBs were a contaminant of concern.
East Branch Grand Calumet River Remedial Action
IAI provided geotextile tube dewatering and water treatment services on this project, processing 145,000 cubic yards of PCB contaminated sediments and successfully treating and discharging 196 million gallons of water under an NPDES discharge permit.
River Raisin PCB Dredging Water Treatment
IAI provided water treatment services for the River Raisin PCB Dredging project. The overall project involved hotspot mechanical dredging of sediment containing concentrations of polychlorinated biphenyls (PCBs) in excess of the 50 mg/kg limit regulated by the Toxic Substances Control Act (TSCA) from deposits adjacent to the U.S. Army Corps of Engineers (USACE) navigation channel […]
Ottawa River Remediation
IAI was the General Contractor for all landside operations on the Ottawa River Remediation Project (2010). The project involved hydraulic dredging of 242,000 cubic yards of contaminated sediment from the Ottawa River near Toledo, OH. IAI was responsible for geotextile tube dewatering in place, water treatment operations, and maintaining separation of TSCA and Non-TSCA regulated material during processing.
Borrow Pit Remediation
IAI provided geotextile tube dewatering and water treatment services for this project, dewatering 14,000 cubic yards of PCBs contaminated sediment and treating up to 1,000 gpm of water flow.
Conner Creek CSO Dredging Project
IAI dredged 180,000 cubic yards of in-situ material from Conner Creek to create capacity for a new combined sewage overflow treatment facility. The project involved the removal of approximately 100,000 cubic yards of contaminated sediments utilizing an 8 inch diameter swinging ladder dredge and an 8 inch diameter auger dredge. A specially designed header system, […]
