Trace metals in surface water and stream sediments of Healy and Lignite Creek Basins, Alaska
Coal has been strip-mined in the Healy and Lignite Creek basins of the Nenana coal field. Trace metals concentrations are low in Healy Creek, but are higher in the Lignite Creek basin. Concentrations of trace metals increase as Healy Creek and Sanderson Creek (in the Lignite basin) flow past mined areas, but effects of coal mining cannot be distinguished from those due to a change in lithology or coal outcrop burning. Metals are typically concentrated on the suspended sediment. The source of the trace metals on sediment and in the water is probably the fine-grained Tertiary rock of the coal-bearing group. Local coals do not contain high levels of trace metals. Concentrations of dissolved and suspended trace metals in water and total-recoverable trace metals in the bed material do not present an environmental hazard in the Healy and Lignite Creek basins at this time. Mining does not appear to have had any appreciable effect on the quality of ground water in the basins. 14 references, 8 tables.
