Even though the nuclear reaction chamber was removed when Camp Century was decommissioned in 1967, an estimated 53,000 gallons of diesel fuel, 63,400 gallons of waste water (including radioactive coolant), and an infrastructure containing toxic polychlorinated biphenyls (PCBs) remains. Unfortunately, a clean-up initiative would be too costly to undergo until a significant amount of the ice melts. This gives the U.S. and Greenland time to figure out who is responsible for the job.
