In Michigan, the Allied Paper/Portage Creek superfund site had soil contaminated with polychlorinated biphenyls (PCBs) across papermill properties, riverbanks, and floodplains. During EQM’s involvement with this project in coordination with the USEPA, activities included:
Excavation, dewatering, and transportation and disposal of 24,000 cubic yards of PCB-contaminated soil.
Backfill and capping excavations.
Placement of river rock along creek banks to enhance fish habitat, restored creek bottom, and used coir logs to reestablish vegetation.
Removal of invasive vegetative species and installed native aquatic and upland species of grasses, bushes, and trees.
