Leadville's mining past includes a Superfund cleanup site

A long mining history leaves more than old buildings. Around Leadville, decades of mining and smelting left heavy metals in some soils and water, and that led to a federal cleanup. The area is known as the California Gulch Superfund site, and it covers part of central Lake County, including land in and around the city.

This is not a reason to panic, and it is not a verdict on any one property. A Superfund listing is how the EPA organizes a long, careful cleanup. Over the years that work has included removing contaminated soil from some residential yards and treating contaminated surface water and groundwater. The EPA’s site profile describes which parts of that work are finished and which are still going.

For a buyer, the practical step is to ask questions rather than assume. Whether a specific parcel falls inside the site, whether any past soil work was done there, and what the current status is are all things to check against official records, not rumor. A calm, informed look beats either ignoring it or fearing it.
