The DEQ is the designated state agency to carry out investigation and remediation of Oklahoma Superfund sites. The largest and most challenging of the Oklahoma sites is Tar Creek.
The Oklahoma portion of the former Tri-State Mining District encompasses more than 40 square miles, five towns, and an entire watershed in far northeastern Oklahoma. Extensive lead and zinc mining and ore processing left tons of mine waste (chat) in huge piles and flotation ponds that contain high concentrations of heavy metals. After mining ceased in the 1970’s the underground mines filled with groundwater which eventually lead to seeps of metal laden, sometimes acidic mine water contaminating streams and shallow groundwater.
Actions at the site have included: groundwater and surface water work, residential property remediation to limit lead exposure in children, mine and smelter waste remediation, investigation of creek sediments, and a voluntary buyout of citizens in the affected area. The following documents and web links cover a multitude of documents and other sources of information that have been produced or are currently available.
