Potential environmental issues consist of heavy
metal, petroleum and solvent impacts to soil and groundwater as
a result of historic disposal activities prior to construction of
the EAF Dust Landfill. Additional environmental issues may be associated
with heavy metals from the dust contained within the open EAF dust
disposal cell. Heavy metal concentrations in leachate samples collected
from the landfill leachate collection system meet the SYSCO effluent
Blast furnace slag was widely used as a fill material in this area.
Various heavy metals are known to be present in blast furnace slag,
but often in a highly immobile state. An important part of future
environmental testing at this site will be the appropriate evaluation
of heavy metal impacts in relations to their environmental risk.
