Description Iron, zinc, copper, cadmium, lead, other metals, and cyanide were analyzed in drainage from the abandoned Holden mine, tailings pile leachate, and Railroad Creek water and sediment collected above and below the mine. Creek samples were subjected to toxicity tests with Ceriodaphnia dubia, Hyalella azteca, and Microtoxâ. The health of Railroad Creek’s benthic invertebrate community was quantitatively assessed.
