Ecology's Environmental Assessment Program Toxics Studies Unit monitors toxic chemicals in Washington's environment. These scientific studies provide the foundation for decisions made by governing agencies to reduce the risk from these toxic chemicals of concern.
Targeted Toxics Studies are short-term focused studies including Total Maximum Daily Load (TMDL) assessments, water cleanup plans, stormwater studies, emerging contaminants, and other specific toxics projects in support of agency-wide initiatives.
Pesticides in Salmon Streams is a collaboration between the Departments of Ecology and Agriculture to study pesticide concentrations in salmon streams during the pesticide-use season. This data has been collected since 2003 to help regulators assess the potential effects of pesticides on endangered salmon species. The program will transfer to the Washington State Department of Agriculture in 2014.
Freshwater Fish Contaminant Monitoring Program samples fish and water across Washington to characterize levels of toxic contaminants and determine changes in levels over time. This project supports a range of agency activities, such as water-cleanup plans, by monitoring a broad range of toxic substances.
Persistent Bioaccumulative Toxics (PBT) Monitoring program conducts long-term studies to evaluate trends of environmental PBT levels over time. Ecology scientists analyze fish tissue, sediment cores, and suspended particulate matter for PBTs such as mercury, lead, and PAHs. This work supports agency Chemical Action Plans.All data for these projects are available through the Environmental Information Management (EIM) database.
NOTICE: The Pesticides in Salmon Streams program will transfer to the Washington State Department of Agriculture on January 1, 2014. The website, including the 2012 Results report, will no longer be available. Contact us for more information.
