Natural attenuation of acid mine drainage (AMD) was investigated at Davis mine, a long-abandoned pyrite mine in Western Massachusetts. Studies at both flask and field scales included monitoring of groundwater hydrology and chemistry, microbial community analysis and flask microcosm studies. The results showed that mixing of contaminated groundwater with water from higher topographies and dissolution of silicate minerals restricts the contamination to a narrow region of the site. Microbial Fe(III) reduction appears to be widely distributed throughout the site, while sulfate reduction is observed in higher pH zones, peripheral to areas of highest contamination.
