Kennecott/RioTinto’s Lies

The Flambeau Mine pit was dug to within 150 feet of the Flambeau River. During the permitting process, people were worried that groundwater polluted with heavy metals from the mining operation would get into the river. Rio Tinto/Kennecott responded by telling the people that there was nothing to worry about because the bedrock between the mine pit and the Flambeau River was like the “Hoover Dam.” The plaque pictured below was actually posted at the mine site:



Rio Tinto/Kennecott also stated the following in a 1991 brochure about the Flambeau Mine:  “The [mine pit] will be located near the Flambeau River and will be separated, at its nearest point, by a 140-foot-wide rock pillar that has the strength of solid concrete and provides a barrier stronger than the Hoover Dam which holds back the Colorado River.”

Only later did the public learn that Rio Tinto/Kennecott had lied. A 2003 open records request of the Wisconsin Department of Natural Resources produced a document (Flambeau Mine Permit Application, Appendix L, page 30/L32 ) revealing that Rio Tinto/Kennecott knew in 1987, before the mine was built, that the rock between the pit and the river was “fractured” and that the contaminated groundwater leaving the mine pit would “flow directly into the bed of the Flambeau River.” That includes the water contaminated with manganese, iron, copper and sulfate shown in graphs elsewhere on this website.

But there is even more to the story. In April 2015 mining engineer/geologist Jack Parker (Jack Parker and Associates, Baltic, MI) reviewed and offered comment on various claims made by Rio Tinto and others with regard to groundwater contamination at the Flambeau Mine site. He also suggested a plan to investigate the extent and degree of groundwater contamination at the site. Please see below.
