IAI provided water treatment services for this mechanical dredging project. The overall project involved excavating impacted sediments from service water ditches at an industrial facility in Michigan. IAI was responsible for treating after the remaining water after the ditches were drained to within one foot of the sediment, as well as any water that … [Read more...]
Dredging Water Treatment
IAI provides water treatment services for environmental dredging, contaminated sediment remediation and coal ash projects. We design, build and operate systems to treat up to 4,000 gpm of water flow, and have successfully treated 1.5 billion gallons of water produced by dredging. Below are some examples of projects where we've provided water treatment services, including Superfund, Superfund Alternative Sites, and Great Lakes Legacy Act clean ups.
This remedial action project utilized hydraulic dredging to remove 145,377 cubic yards of contaminated sediment from the Grand Calumet River. IAI was responsible for the sediment dewatering and water treatment portions of work. The sediment dewatering pad was installed over a brownfield site in East Chicago, where the contaminated sediment was … [Read more...]
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 … [Read more...]
IAI was the General Contractor for all landside operations on the Ottawa River Remediation Project, which was conducted over the course of the 2010 construction and dredging seasons. The project involved hydraulic dredging of 242,000 cubic yards of contaminated sediment from the Ottawa River near Toledo, Ohio. The dredged sediment was pumped by the … [Read more...]
Summary During this project, 14,000 cubic yards of contaminated sediment was hydraulically dredged from a former borrow pit and dewatered in geotextile tubes. An existing asphalt parking lot was converted into a geotextile tube laydown area with the installation of temporary sand berms and a high density polyethylene (HDPE) liner. Eighty foot … [Read more...]
