EPA Superfund Case Study
Leadville Lake County Community Park

For over 140 years, Leadville, Colorado was home to silver, gold, copper, zinc, manganese, and lead mining and smelting. When operations ceased in the late 1980s, the area was left with significant amounts of mine waste, contaminated soil, and acid mine drainage.
Eventually declared a Superfund Site, the area was redeveloped into a community park and the 11.6-mile Mineral Belt Trail featuring preserved historic mining structures. The paved trail also serves to cap and contain onsite the contaminated soil from the former mining activities. The containment process left the contaminated soil in place, shaped it into a platform for the future trail, covered it with six inches of gravel, and then capped it with three inches of asphalt. The park includes a synthetic turf field, restrooms, and a playground.
