Superfund Record of Decision (EPA Region 9): Iron Mountain Mine, Redding, California, October 1986. Final report

Technical Report · Fri Oct 03 04:00:00 EDT 1986

OSTI ID:6174394

Iron Mountain Mine (IMM) was periodically mined for iron, silver, gold, copper, zinc, and pyrite. Rainfall, infiltrating into the underground mine workings mixes with ground water and the ore zone to produce sulfuric acid and high concentrations of zinc, cadmium, and copper. The resulting heavy metal-laden acidic waters, referred to as acid mine drainage (AMD), was eventually discharged through mine adits or ground water seepage into the Spring Creek watershed streams, Spring Creek Reservoir, and the Sacramento River. The primary contaminants of concern include: AMD, copper, cadmium, and zinc. The desired remedial action for this site was not selected due to excessive cost. Alternatives were proposed and are detailed in the report.
