Stormwater Awareness Week

While stormwater might seem like a small part of the larger environmental picture, its impact is far-reaching. How we manage, protect, treat, and discharge stormwater plays a crucial role in safeguarding and restoring our environment.

Whether you're a municipality striving to keep stormwater clean, a construction site managing erosion and sediment control, an industrial facility improving housekeeping practices to meet stormwater sampling goals, or simply someone passionate about environmental protection, we invite you to join us for this year’s Stormwater Awareness Week.

Stormwater Awareness Week Events

All events are FREE


November 12th


  • IDDE/Spill Control Workshop 8:00 – 11:30 AM

Location: Virtual/Online

Since 2002, the TAPE program has provided a way to evaluate the pollutant removal efficiency of stormwater treatment technologies. The TAPE Guidance Document has been updated 5 times over the years, with the most recent update being completed last month. This recent update has focused on providing a better way to assess the maintenance requirements of these technologies – both the maintenance frequency and the level of maintenance necessary to ensure the effective operation of these technologies. This presentation will provide an overview of the recent TAPE updates and highlight the importance of factoring maintenance when selecting and sizing stormwater treatment technologies.

  • Gaining Traction: A Tire Story of Where We Started, Where We Are Now, and Where We Are Going 12:00 PM – 1:00 PM

Location: Virtual/Online

In 2020, a collaborative group of researchers with the Washington Stormwater Center identified 6PPD-quinone (6PPDQ), a novel chemical leaching from vehicle tires, as the primary causal toxicant of pre-spawn mortality in coho salmon (Oncorhynchus kisutch) in the Pacific Northwest. Since its discovery, 6PPDQ has been shown to be toxic to several species of fish at environmentally relevant concentrations. The ubiquitous presence of tires worldwide presents a unique problem as this contaminant is present in nearly all locations that have been sampled. The urgency of this issue has led to rapid developments in the research surrounding 6PPDQ and other tire-related contaminants. This presentation will cover how researchers linked stormwater and tire chemicals to coho mortality, what we have learned about 6PPDQ since its discovery, and provide an overview of current research being performed in the aquatic ecotoxicology lab at Washington State University’s Puyallup Research and Extension Center.

Melissa is a Postdoctoral Research Associate under Dr. John Stark and Dr. Jenifer McIntyre at the Puyallup Research and Extension Center for Washington State University. After earning her BS in Zoology from Miami University in 2007, she headed north to the University of Saskatchewan to complete her M.Sc. and Ph.D. Her Master’s work was part of an extensive assessment of mining and milling effluents on the aquatic health of a northern lake system. Her collaborative work using field-based mesocosms and laboratory-based studies helped establish the transformation pathways of selenium through a complex ecosystem. She began her Ph.D. research in 2012, which focused on evaluating the impacts of complex mixtures on aquatic species using a combination of mesocosms, tissue cultures, and molecular techniques. Melissa’s current research is focused on understanding how chemical exposures (e.g., 6PPD-Q, rodenticides, PCBs) impair salmon health as well as aquatic invertebrates from both an organismal level and an ecosystem-health based perspective.
