zinc mining contaminated

Picher, Oklahoma Wikipedia

This was a major national center of lead and zinc mining at the heart of the Tri-State Mining District. More than a century of unrestricted subsurface excavation dangerously undermined most of Picher's town buildings and left giant piles of toxic metal-contaminated mine tailings (known as chat) heaped throughout the area.

Zinc speciation in mining and smelter

The Zn concentration ranges from 3200 to 69,000 mg/kg. Contamination undoubtedly results from the past mining and smelting activities because the overbank sediments at 5 km upstream of La Calamine contain less than 400 mg/kg (data not shown). The LC profile is the most contaminated in zinc, with Zn concentrations above 10,000 mg/kg.
