Location of RECs for the foundry portion of the site.

detected in groundwater included low levels of LNAPL VOCs, PAHs, and SVOCs, with
none requiring remediation except for several areas with PAH-free product. Contaminants
requiring remediation in soil included PAHs, PCBs, lead, and mercury.
Figure 14.23 shows most of the RECs are associated with the foundry located along the
river on the west-northwest portion of the site. Within and near the foundry, the sources of
contamination included sumps, pits, trenches, floor drains, and outdoor storage of waste
materials where accidental spills had occurred.
