| Short Description |
This screening-level study is designed to characterize water and sediments in streams in the vicinity of selected inactive or abandoned metals mines or mining districts. Drainage from a few selected mines may also be opportunistically sampled to compare to the adjacent stream chemistry. The study will be conducted by staff from the Department of Ecology′s Environmental Assessment and Water Quality Programs along with the Department of Natural Resources Division of Geology and Earth Resources. This study is similar in design to two previous studies conducted by the same staff in 1997 and 2000. (Also see abstract below) | |||

| Abstract | Long Description |
This screening-level study is designed to characterize water and sediments in streams in the vicinity of selected inactive or abandoned metals mines or mining districts. Drainage from a few selected mines may also be opportunistically sampled to compare to the adjacent stream chemistry. The study will be conducted by staff from the Department of Ecology′s Environmental Assessment and Water Quality Programs along with the Department of Natural Resources Division of Geology and Earth Resources. This study is similar in design to two previous studies conducted by the same staff in 1997 and 2000. Candidate mining districts were screened based on information in a database of inactive and abandoned mines created and maintained by the Washington Department of Natural Resources. Districts were selected based on the size of the mines or dominant mine in the district, variations in geologic host rock among districts, presence of tailings in or adjacent to a stream, the primary and secondary minerals in the ore deposit, geographic distribution of districts around the state, and a consideration for including some high elevation sample sites. The water quality emphasis for this study is the EPA ultra-clean sampling and low-level analysis methods for metals in surface water. General chemistry and field parameters will be obtained concurrently with the metals and sediment samples. Water and sediment samples will be collected upstream and downstream of each mining district during fall 2002 for low flow conditions and water samples will be collected during spring 2003. Results will be compared upstream to downstream, seasonally, and to state surface water quality standards and sediment quality guidelines. |
