Potential environmental issues consist of heavy
metal, petroleum, PAH, PCB, and solvent impacts to soil and groundwater
as a result of impacts from the adjacent High Dump or Tank Farm
areas, as well as historic disposal activities within SCU 34.
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.
