The Neihart Tailings source is comprised of approximately 23,100 cubic yards of uncovered tailings located in two piles. Carpenter Creek is the primary drainage basin at the site and eventually flows into Belt Creek. Snow Creek is also a tributary of Carpenter Creek where several mines, tailings piles, and mills are located. Copper, lead, manganese, and zinc are present in total metals analysis of surface water release samples. In sediment release samples, arsenic, barium, cadmium, copper, lead, manganese, and zinc.
Belt Creek is classified as a fishery and is subject to actual contamination.
Surface water release samples contained copper, lead, manganese, and zinc at concentrations three times background concentrations that were attributable to the site. Sediment release samples contained arsenic, barium, cadmium, copper, lead, manganese, and zinc at concentrations three times background concentrations that were attributable to the site. The description may change as additional information is gathered on the sources and extent of contamination.
