// Strategic Significance
The Anaconda Smelter in Deer Lodge County Montana is one of the largest Superfund sites in the US covering 300 square miles. Over 100 years of copper smelting deposited arsenic lead and other heavy metals across a massive area. The 585-foot smelter stack is the tallest masonry structure in the world and is preserved as a state park landmark.
// Civilian Impact Assessment
Anaconda and Deer Lodge County residents live in one of the most heavily contaminated regions in the US with arsenic in soil at levels far exceeding safety standards. Residential soil replacement has been conducted for hundreds of properties.
// Evacuation & Shelter Guidance
Deer Lodge County residents should follow EPA and MDEQ guidance on soil contact restrictions. Residential soil in Anaconda continues to be tested and replaced in the most contaminated areas.
