Description This report provides upper-bound upland background concentrations for 18 metals across 11 state-designated watersheds in northeast Washington State. Determinations and analyses use existing data from multiple regional soil and tributary assessments. Comprehensive exploratory analyses are performed to select data and determination comparability. Advanced statistical analyses inform the selection of 90th percentile background concentration ranges for applications within the study area.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
