Contaminants in Puget Sound

The Ecotoxicology Program has been actively engaged in research addressing impacts to Puget Sound fauna resulting from contaminant exposure for more than four decades. Puget Sound is a complex estuary with several relatively pristine areas and many that are contaminated as a result of wastewater treatment plants, industrial activity, runoff from impervious surfaces and other modified areas (e.g., farms, ranches, and logging), and chemical spills. The list of contaminants is diverse and includes a large number of persistent organic pollutants (POPs), industrial chemicals, metals, pesticides, polycyclic aromatic hydrocarbons (PAHs), and other difficult to classify chemicals.

Recent work involves studies on contaminants of emerging concern (CEC), which are chemicals with very little data on environmental occurrence and toxic effects. A further focus of our work is the monitoring of fish health prior and subsequent to various types of remediation efforts conducted at sites in Puget Sound (e.g. a Superfund site at Eagle Harbor near Winslow, WA). This research supports Endangered Species Act (ESA) consultations, Natural Resources Damage Assessments (NRDA), and other risk assessments.
