The Milltown Superfund Recap

In 1908 a massive flood washed millions of cubic yards of toxic mine wastes into the Clark Fork River system. Generations later, in 1983, the Milltown Reservoir was listed by the Environmental Protection Agency as a Superfund site after the discovery that several million cubic yards of heavy metal contaminated sediments had piled up behind the dam, polluting the groundwater beneath with high concentrations of arsenic.

The Three R's of the Milltown Reservoir Superfund Project

thumb_dam-news-08-small The project now underway at the Milltown Reservoir is one of the nation's most challenging and ambitious environmental cleanups. It is an effort that integrates what's known as the Three Rs, remediation, restoration and redevelopment.

The Other End of the Dam Project

As of June 2009, more than 1.9 million cubic yards had been shipped from the Milltown site to the BP ARCO waste repository at the Anaconda Superfund site. More than two million cubic yards will shipped in total. At the repository, roughly 80,000 cubic yards of reservoir sediments are scooped daily from one train with 45 rail cars. The daily process of unloading, spreading, and seeding sediments will continue through late 2009. All in all, the material from Milltown will cover less than a quarter of the waste repository, or about 800 out of 4,000 total acres.
