| Description | The Department of Ecology detected several instances of elevated mercury concentrations at the mouth of Leach Creek in Tacoma during water quality monitoring in 2007-08. During 2009-10, Ecology conducted a follow-up study to better characterize mercury levels in the creek and assess specific reaches as sources. Copper concentrations were also analyzed. Water quality violations were detected for mercury and copper in Leach Creek. Sources appear to lie towards the upstream end of Leach Creek. It is recommended that Leach Creek be placed in Category 5 (303(d) list) of the state Water Quality Assessment as being water quality limited for mercury and copper. |
