| Description | This study summarizes results from the eighth year of sampling lead in suspended particulate matter (SPM) as part of the PBT trend monitoring program. The Department of Ecology analyzed a total of 28 SPM samples from seven monitoring sites in 2015. Lead concentrations ranged from below detection limits to 770 mg/kg, with a median of 177 mg/kg. The highest levels were found in the Spokane River, followed by urban streams and the Upper Columbia River. A small sediment trap pilot study initiated in 2015 will be discontinued. Other recommendations include increasing sampling frequency and adding more small streams to the monitoring site list. |
