The prevention measures from harmful sediment flowing into the Flathead River from the closed down Columbia Falls Aluminium Company have been commenced. This is the first remediation project to take place at the Columbia Falls Aluminium Company Superfund site.
John Stroiazzo, CFAC Project Manager said: “The Flathead River is slowly eroding the banks of two ponds used by the now-defunct aluminium company. The ponds contain harmful sediment.”
"We don’t think that these ponds will last another two years."
This has been the major reason; the U.S. Environmental Protection Agency approved the work ahead of schedule. The two-year project, which will begin this fall, also incorporates the removal of dams that will return the Flathead River to its original channel.
Various researches have determined the level of contamination and upon that remedial action needs to be taken in the remaining units of the superfund site which are still on process.
Stroiazzo added: “Work to remove contaminants in those units could begin in about three years.”
