The metal comes from the former Callahan copper mine. Tuesday night, residents heard what officials have concluded about the potential hazards.
The mine was closed down more than thirty years ago, but the contamination in the environment is still a concern in Brooksville. The Maine Department of Transportation and the federal Environmental Protection Agency have done a study to determine how much damage has been done. The study precedes a clean up that the D.O.T. is committed to do.
Some residents are concerned about the elevated level of metals, others say the dangers are overblown.
The investigation will conclude in September of 2008. Then the clean up will begin.
