In September 2014, EPA and the U.S. Fish and Wildlife Service released an initial assessment of contamination at Tern Island, a remote island in the chain of Northwestern Hawaiian Islands (NWHI). The results show that there have been releases of hazardous substances such as polychlorinated biphenyls (PCBs) and lead from military wastes buried on the island between World War II and 1979, and further action is warranted.You may need a PDF reader to view files on this page.
