dc.description.abstract | Assesses mine site consisting of a large collapsed adit and approximately 700cy of wasterock material adjacent to Granite Creek, with numerous trenches stemming from hydraulic mining and possible historic dredging operations. A Niton XLt unit found that most metals at the site exceeded screening criteria for birds, invertebrates, and plants, but only arsenic (79 mg/kg) exceeded EPA Region goals. The site has been given a High Priority. | en |
