Abstract
Assesses mine site consisting of a large collapsed adit and approximately 500cy of wasterock material adjacent to Granite Creek, with numerous trenches and apparent hydraulic mining. A Niton XLt unit found that most metals at the site exceeded screening criteria for birds, invertebrates, and plants, but only arsenic (59.7 mg/kg) exceeded EPA Region goals. Since the wasterock forms a part of the embankment for Granite Creek, the site has been given a High Priority for further site assessment.
