Tar Creek Superfund Site - Ottawa County, OK

    Tar Creek Oklahoma

    Background Information

    The Tar Creek Superfund site is located in far northeastern Oklahoma (Ottawa County), near the Oklahoma/Kansas state line (Figure 1). The site comprises a 40-square mile area and includes the communities of Picher, Cardin, Quapaw, North Miami, and Commerce. From the early 1900s through the late 1970s, northeastern Oklahoma was mined extensively for lead and zinc ore. The milling process for lead and zinc ore produced waste mine tailings, known locally as “chat.” Over the years miners disposed of the chat by accumulating it in large, aboveground piles, and by dumping it into flotation or tailing ponds.
