Superfund Site Profile
The Callahan Mining Corp site is located about 1,000 feet east-southeast of Harborside Village in Brooksville, Hancock County, Maine. The site is the former location of a zinc/copper open-pit mine that operated from the 1880s to 1972. The mining operations were next to and beneath Goose Pond, a tidal estuary. Mining operations contaminated soil, sediment and groundwater with metals and polychlorinated biphenyls (PCBs). Site investigations and long-term cleanup are ongoing.
