Mining and wildfires are both landscape disturbances that pose elevated substantial hazards to water supplies ecosystems due increased erosion transport of sediment, metals, debris downstream waters. The risk may be amplified when these occur in the same watershed. This work describes mechanisms by which intersection mining wildfire lead metal concentrations waters: (1) conveyance metal-rich ash soil surface waters, (2) dissolution dissolved metals direct contact precipitation with mine waste, (3) sediment from (4) remobilization previously deposited metal-contaminated floodplain higher postfire flood flows, (5) underground workings. Predicted increases size, frequency, burn severity, together ongoing need for resources, indicate improved mapping, monitoring, modeling, mitigation techniques needed manage geochemical hazard implications availability.
