London Mill Water Treatment Plant

In 1996, GSHI began operating the London Mill Water Treatment Plant under an earlier agreement the EPA. The lime plant treats water pumped from the McPherson Mine, the Isabella Collapse and upper Burra-Burra Creek. Pumping from the mines prevents gravity discharges to the stream. The treated effluent from the lime plant was relocated in 2002 from Burra-Burra Creek to McPherson Branch upstream of the wetland outlet.

Ruins of the London Mill flotation plant and adjacent waste areas dominate the stream banks of Burra-Burra Creek upstream and downstream of the retention pond where runoff is collected. Upstream of the mine ruins, Burra-Burra Creek exhibits good water quality, including water impounded on the 120 hectares (300 acres) of tailings located on the the north-western corner of the site. The tailings were the site of soils and revegetation studies by University of Tennessee - Knoxville and were recently revegetated with warm and cool season grasses and several thousand tree and shrub stems.
