(Authors' abstract). Water quality was investigated in 20 streams and 6 mineralized seeps in the Kantishna Hills mining district in Denali National Park from 17 June to 1 September, 1983. Water quality testing and heavy metal analyses were conducted on stream water. Arctic grayling tissues were analyzed for histopathological change and heavy metal concentrations. Preliminary findings indicate that settleable solids, turbidity, and certain heavy metals significantly impact the water quality and fish habitat of several mined streams in the Kantishna Hills. Unmined control streams supported fish populations and presented acceptable water quality. Management and research recommendations are made in light of 1983 summer field investigations.
