Description | A laboratory test was conducted to simulate potential release of metals and cyanide during placer dredging for gold in the Similkameen River. Results indicated state water quality standards may be exceeded for copper and lead. Given the size of the river, metals concentrations downstream of the small-scale recreational dredger would be rapidly diluted. No cyanide was detected in the test sediments. | ||||
