Potential environmental issues associated with the
existing building and structures include asbestos containing material,
lubricants, lead-based paint, PCB-containing equipment, ozone-depleting
substances, mercury-containing equipment and lighting, and petroleum
and chemical storage.
Potential environmental issues related to soil and groundwater
consist of petroleum hydrocarbons, heavy metal, and solvent impacts
as a result of historic on-site activities, as well as possible
infiltration of Tar Ponds contamination such as heavy metals, PAHs,
PCBs, and HNCs. Coal tar-impacted sediment may lie beneath the fill
used to create that land .
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.
