Soil and Ash Results

The department has collected soil and ash samples, which are being analyzed at the state laboratory, operated by the Tennessee Department of Health.  Results are being posted to this page as analysis is completed.  Both soil and ash samples are being analyzed for total metals, TCLP metals (which helps to determine how likely metals are to leach from the material), radioactivity and polynuclear aromatic hydrocarbons.

Soil and ash samples were collected from residential locations, from the landfill itself and soil samples were collected near Roane County Park (link to map titled 'background samples') away from the spill to determine background levels present in unaffected soils for comparison purposes.
