annapolis lead mine

EAST SIDE OF IRON COUNTY ROAD 138

The Annapolis Lead Mine (the site) site is located approximately one mile east-northeast of Annapolis, Missouri. The site is arranged into three operable units for administrative efficiency in conducting environmental cleanups. Operable Unit-1 is defined as the Sutton Branch Creek flood plain and the historical mining areas. The northern portion of Operable Unit-1 is located along Iron County Road number 138 north of State Highway 49 and extends south along the Sutton Branch Creek flood plain to Highway 49. That portion of the site lies on either side of the county road. Runoff from the mine works and waste piles entered Sutton Branch Creek which runs near the western boundary of the site. The western boundary of this portion of the site is the western edge of the Sutton Branch flood plain. The southern portion of Operable Unit-1 begins south of Highway 49 and follows the Sutton Branch Creek flood plain south into Big Creek. Operable Unit-2 is defined as Big Creek from the mouth of Sutton Branch Creek downstream to the confluence with the St. Francois River. Operable Unit-2 is approximately 20 miles in length. Operable Unit-3 is defined as the soil in the town of Annapolis, Missouri. Residences north of Operable Unit-1 were also included in the Remedial Investigation of Operable Unit-3. The majority of the work at the site has focused on Operable Unit-1 (the source area). The site property boundary is roughly rectangular in shape. It is bordered to the east and west by wooded uplands. A residential plot lies to the north and Big Creek is the southern boundary. The dominant features at the site include a 10 acre tailings pile, building foundations that are remnants of the former mining operations and Sutton Branch, including its flood plain. The tailings pile has in the past been severely eroded due to surface runoff. Rough estimates of the amount of tailings that have migrated or have been hauled offsite could easily be in the hundreds of thousands of tons. There is coarser-grained mining refuse, ranging from sand/granule size up to cobbles and boulders, around the remains of the former mining operations. The above mentioned materials have been consolidated into the tailings piles and contained with a cover. This is the result of an EPA lead removal action. The mine area and the tailings piles no longer represent a threat or source of contaminated sediment for the downgradient bodies of water.
