Superfund Site Profile
The Pike Hill Copper Mine site is an abandoned copper mine in the town of Corinth in Orange County, Vermont. Two mines, eventually designated as the Pike Hill Mines, operated on an intermittent basis from 1847 until 1919, when mining operations ceased. Between 1863 and 1918, the mines yielded about nine million pounds of copper. The site’s mine tailings are rich in metals and sulfides. As water passes over and through the tailings, sulfuric acid is produced and the metals within the tailings are dissolved and mobilized. This results in acid mine drainage. Site investigations and cleanup planning are ongoing.
