St Marys River cleanup continuesEnvironmental Issues // October 18, 2006
Associated Press (AP) reports that an US$8 million clean-up of contaminated sediments from the St Marys River in Michigan in the US is beginning its second month.
The clean-up of contamination from a former leather tannery is a co-operative venture of the US Environmental Protection Agency, the Michigan Department of Environmental Quality and Phelps-Dodge, present owner of the property.
AP said dredging will continue on a 15-acre site just offshore of the old tannery property until late November.
If the work isn’t finished by then, it will be delayed until next spring.
The clean-up plan calls for removal, separation and treatment of 40,000 cubic yards of material which eventually will go to a landfill.
The EPA estimates about 500,000 pounds of chromium and 25 pounds of mercury were dumped by the leather tannery during its 60-year operation.
The company closed after a fire in 1958.
