Every time it rains, water washing off roads and highways carries pollutants into nearby streams, rivers, and estuaries. One of the most concerning pollutants is 6PPD-quinone (6PPDQ), a chemical byproduct of a common tire rubber additive that is among the most toxic substances known to aquatic life. This podcast introduces 6PPDQ to planners and technical staff who may be encountering it for the first time and shows what communities can do about it. Speakers from Washington State DOT, Herrera Inc, and Stewardship Partners will share lessons learned from using green stormwater infrastructure as a solution and discuss how municipalities, transportation agencies, and nonprofits can work together to deploy solutions, engage their communities, and access funding.
Speakers:
- Tony Bush, Stormwater Branch Manager, Washington Department of Transportation (WSDOT)
- Dylan Ahearn, Principal Scientist, Herrera Inc
- Soumi Gaddameedi, Grants & Development Manager, Stewardship Partners
- Katie Harris, Greenprint Partners (moderator)
